Timex Ironman GPS Global Trainer In Depth Review

When the Timex Global Trainer was announced earlier this year, most folks were quite excited to see a new entrant into the triathlon watch/device scene.  With the watches ANT+ capabilities and full waterproofing it would make ideal training partner for any triathlete, as well as runner or cyclist.  And because it was GPS based, it would also work with the myriad of other activities that people like you and I dream up.  Finally, it actually looked like a normal Timex watch – a huge plus in many triathletes minds.

I went out and purchased the Timex Ironman GPS Global Trainer (just like any other athlete) in early June and after writing my First Look Review then, I’ve been using it constantly since.  During this time I’ve quite simply beat the crap out of it, and picked every little detail apart.

I’m also had the opportunity to sit down with the full Global Trainer development team at Timex, as well as the folks at Training Peaks.  During my discussion with them I grilled them for over an hour on everything and anything I could think of, and their answers in turn made there way into this in depth review.  As a result, I’m fairly confident that if you have a question about the device…the answer is probably in here. 😉

Lastly, before we get to the grand un-boxing, note that I’m just an athlete like you.  I look for the best device for my money, and this review is simply a way to detail out what I think of what I’ve purchased.  If you’ve read my in depth reviews before, you’ll know that I’m pretty in depth – perhaps overly so.  But that’s just my way of doing things.  Think of them more like a reference manual than a simple ‘Should I buy this’ type of review.  If you find something that doesn’t quite jive – feel free to let me know and I’ll double-check and get it all sorted out.  Thanks again for reading!


When you first get the unit, it’ll look something like this:

After you go ahead and unwrap all the components, you’ll be left with the following pile of goodies:

Let me go ahead and label them:

And let’s go step by step through each one.  First up, is the watch itself:

Tucked away as a clever piece of packing, is actually the bike mount – which I missed when I first took the initial unboxing pictures, but thankfully didn’t throw away:

And finally, last but not least, is the nifty paper quick start guide:

Size Comparisons:

When the watch was first announced, most (like myself) were pretty excited to see a GPS watch in a semi-normal looking wrist form factor.  However, when I finally got a hold of my Global Trainer, I realized that while it looked normal…it was actually just about the same size as all the other large GPS watches out there today.

Timex Global Trainer Review Mode

But…you probably wouldn’t notice that unless you put it next to a normal wrist watch:

Timex Global Trainer with Garmin FR60

Of course – in order to compare it against something in the same class of features and functionality…there’s only one solution: The kitchen rolling pin.  This technological advancement has allowed me to easily compare half a dozen GPS watches at a time.  And thus – I present my masterpiece:

Timex Global Trainer Size Comparison

(Left to right: Garmin Forerunner 110, Garmin Forerunner 405, Garmin Forerunner 305, Garmin Forerunner 310XT, Timex Global Trainer)

Timex Global Trainer Size Comparison

As you can see, the Forerunner 310XT and Timex Global Trainer are virtually identical in both thickness, and in size.  It’s only when you compare it against less capable GPS watches (such as the Forerunner 110 or Forerunner 405) that you’d notice the larger size.

Timex Global Trainer Size Comparison

However, like all GPS watches I use – in general I find that you just simply don’t notice the size beyond the first few seconds of running with it.  Yes, it looks funny at first, but realistically, if you want four data fields that are actually human readable, that’s pretty much the size the screen will have to be.

That said – the most common question I usually get regarding size is ‘I have small wrists…’.  So I present you with my girlfriend, who at just over 5’, also has small wrists.  While we had to ratchet down the strap all the way, it does fit.

Basic Operation/Modes:

Before we get into all the detail on all the different modes, let’s get into a basic primer of the watch.  First up – turning it on.

To turn it on, you’ll simply hold down the left center ‘Pwr’ button for a few seconds, which will change it from standby mode (which has the time shown) to full blown sports watch.  Once you do that, you’ll be in the default Performance mode:

Timex Global Trainer Performance Mode

This is the mode where you’ll do most of your activities. The watch has the following modes:

– Performance Mode (default activity mode)
– Multisport Mode (for triathlons)
– Navigate Mode (to use for basic GPS/compass navigation)
– Review Mode (to review historical data)
– Configure Mode (to change configuration options)
– PC Sync Mode (when you want to download activities & settings to computer)

So with that, let’s get into using the watch…

On the run:

The first activity you’ll probably partake in with the TGT is running, mostly because that’s the easiest to get up and start with.  As noted above, after turning on the watch, you’ll be put into ‘Performance’ mode, which is simply a fancy word for ‘Go mode’.

Performance mode is one of a number of the modes I listed earlier that the TGT uses, and is the primary mode that you’ll use for most training and racing activities (save for multisport mode).  Performance mode has five screens (called views) that you can customize with up to four data fields you’d like to display – such as ‘Time’, ‘Distance’, ‘Speed’, etc…  I’ll talk more about that later on in the software configuration piece.

But first…let’s get running.  Assuming you’ve powered the watch on, and satellites have been acquired, simply press the big button on the bottom to start.

Timex Global Trainer Running

Now that we’ve started the watch – we should start running too.

Timex Global Trainer While Running

As you run you’ll notice that the screens continuously update with the information you’ve selected.  You’ll see the pace fluctuate gradually while you run, though much less pronounced than on many other GPS watches.  The folks at Timex have brilliantly put a smoothing factor in the run paces of about 5-7 seconds averaging, which removes much of the highly erratic paces folks sometimes see with GPS watches, by simply averaging the pace over the last 5-7 seconds.

You can switch to any of the other screens (views) that you’ve defined if you want to see other information.  You’re able to configure up to four pieces of information per screen (though you can have less and make the size larger like below).  To rotate through the screens, simply press the up/down buttons on the left side.

Timex Global Trainer While Running Alt Display

The side buttons are pretty sensitive, and as such, I find it useful in certain situations to lock them (such as if you were wearing a heavy jacket in the winter, or if you just tend to bump into stuff).  To lock the buttons, just hold down the Enter key for a few seconds, and the screen will lock.  Do the same again, to unlock.

Timex Global Trainer Locking

Probably the most common item that folks want to know is how fast they just ran that ‘last mile’ (or ‘last kilometer’ for all you non-US folk).  You can of course just do the simple math via distance divided by time…but it’s much easier if you use Auto-Split.  This feature will automatically demark a lap at any interval you choose.  For example, every 1 mile, or even every 1.87 miles (seriously, anything).

Timex Global Trainer Auto Split

On top of that, you can also auto-split at any time interval as well.  This is useful if you’re doing workouts based on time sets (such as 5 minutes easy, 5 minute shard).  You can change the auto-lap settings directly on the watch (like above), or also using the Training Peaks software (like below).

Timex Global Trainer Configuration Settings

While running, once a lap has been triggered, it will automatically display summary information for that lap, such as heart rate, pace and speed.

Timex Global Trainer Lap Summary

Laps are a useful way to record smaller groups of information, as they then show up within Training Peaks online, allowing you to analyze just that lap – as well as the run/ride in whole.  I use laps to break apart my workouts, for example, if I’m doing a 10 minute warm up first, I’ll press lap at the end of that, and then again at the end of me next set.  This allows me to easily analyze the important parts of the workout, without having warm-up (or cool-down) data skew the results.

Another popular feature is the ability to create alerts.  Alerts are different from laps in that they don’t actually demark anything in your activity file.  Instead, they simply alert you to information while using the device.  Basically, it’s like someone screaming a reminder at you.

You can configure alerts for many different areas, such as Distance, Heart Rate, Power, Speed/Pace, Cadence, and Altitude.  Though interestingly missing is ‘time’.  For example, the ability to create a recurring time alert every 10 minutes reminding you to drink water.

That said, I use alerts quite a bit during races – to help me focus on staying within a given heart rate or power zone.  By using this same functionality on the Timex Global Trainer, I can be reminded if I stray out of zone – helping me to better pace a race.  Alerts can be both visual, as well as audible.  There are no vibrating alerts in the Timex Global Trainer.  When I asked the engineering team why – they explained it helped to keep the cost down, and thus one of the reasons why it’s $50 cheaper than its primary competitor.

Timex Global Trainer Configuration Options

You can configure alerts both on the watch, as well as within the software.  Trust me, it’s a heck of a lot easier to do in the software:

Timex Global Trainer Alert Options

The watch itself is super-easy to handle while running.  Unlike some running watches where you have to press really hard to get the buttons to press (or have to use a touch-bezel), the TGT buttons easily depress.  This won’t be a hard watch to operate once winter rolls around and you have thick gloves on.

Also, the watch is water-proof, so it’s resistant to sweat – and I find it’s super easy to wipe any sweat off the display if you sweat like a sprinkler system.  I’ll talk more about waterproofing in the swim section though.

Finally, I want to cover the ‘Performance Pacer’ functionality – which is similar to what the competition calls their ‘Virtual Partner’.  The Performance Pacer functionality allows you to set a defined target distance and time, and it’ll automatically help pace you during that effort.  Think of it as having a computerized friend.  It’ll tell you how far ahead/behind you are on that goal.  This is great for races where you want to hit an exact time, but don’t want to go out too hard (or too slow).

You configure the feature via the watch or the software:

Timex Global Trainer Performance Pacer

So, with running out of the the way…let’s get onto the bike.

On the bike:

The Timex Global Trainer includes a bike mount, so the first think you’ll want to decide is whether or not to wear the watch on your wrist, or use the included bike mount:

Timex Global Trainer Bike Mount

Once you make that decision – it’s time to get it (or you) on the bike.  The watch simply wraps around the mount, which in turn wraps around your handlebar:

Timex Global Trainer Bike Mount on Road Bike

If you have a tri-bike (aka Time Trial bike), then you’ll need to decide where exactly you want to put it.  On my bike, it only fit on the side of the aeropads.  Functional, yes.  Ideal, no.  Ideally they would have included some sort of quick-mount system so I could put it wherever I’d like (such as up on the bars).  Nonetheless, here ya go:

Timex Global Trainer Bike Mount on Tri BikeTimex Global Trainer Bike Mount on Tri Bike

Ok, so with all the mountage out of the way, let’s get to using the device.  Like run mode, you can customize any of the give views to be bike-specific.  In fact, there’s nothing stopping you from making five bike views if all you want to do is bike.

Specific to the bike views are fields such as cadence, power, and speed (instead of pace).

Timex Global Trainer Bike Mode

Once you get started on the bike, you can change views just as you would with running, by pressing the up/down buttons.  This is probably a good point to mention that the TGT doesn’t have a specific ‘Bike mode’, or ‘Run mode’, but rather just ‘Performance mode’ – and everything you view data wise is just controlled by the display views you’re using at that time.

Timex Global Trainer Bike ModeTimex Global Trainer while Cycling

If you have an ANT+ speed/cadence sensor, you’re able to scan for those ANT+ sensors and add the data being streamed from them.  The ANT+ speed/cadence sensors allow you to pickup cadence – how many times per minute you rotate the crank (where your pedal attaches), and the speed portion of the sensor allows you to get speed while indoors on a bike trainer, or if in a location where satellite coverage is spotty.  Also, some folks explicitly use the speed sensor to get a very exact speed (since it’s simply wheel circumference calculations).

Timex Global Trainer while Cycling

Regardless of why you use the sensor, to configure it, you’ll switch over to Configure Mode, via the mode button, and then scroll down to sensors.

Timex Global Trainer Sensor Scanning

From there you’ll tell it to scan for the sensor type you have.  Note that Timex has only in the last few days made the Timex Speed/Cadence sensor available and only via calling customer service.  For most everyone else out there, you’ll probably be using any ANT+ compliant sensor, and most likely just using the Garmin GSC-10 speed/cadence sensor (sorta the mainstay of cyclists everywhere).  This $35 speed/cadence accessory is money well spent, and it’s what I use on all my bikes.  Since Timex didn’t have the speed/cadence sensor available yet, I’m using the GSC-10 instead in this review.

Timex Global Trainer Speed/Cadence Sensor

Once paired, you’ll see the sensor display cadence information on the screen using the data fields I’ve chosen.

We’ll talk about some of the other ANT+ sensor types in a moment, specifically, power meters.

But first, let’s cover auto-resume.

I’m sure you know the feeling of city riding where you’re constantly pressing stop or start as you hit stop lights…only to realize about 2 miles later that you forgot to hit resume/start at one of the lights.

Well, auto-resume is here to solve that.  This feature allows you to configure a trigger speed where if you go below it, it will automatically pause the watch.  And once you go above that speed, it will automatically resume it.

You can configure this view on the watch itself, or via the software settings.

Timex Global Trainer Auto Start/Resume

Once configured and you’ve started your ride it’ll automatically pause and resume when you cross the threshold.  Note that this function works not only in cycling, but also running (or anything else you happen to use the watch for).

The watch also supports the ability to show ascent/descent using the GPS-based altimeter that’s included within it.  You can configure these settings on the watch or via the software, and display them in your data fields.

Finally, you can customize up to five bikes on your Global Trainer.  Each bike includes separate weights, as well as wheel sizes (used to compute distance indoors), and also can have unique names:

Timex Global Trainer Bike Configuration

With the basics on the bike set – let’s get onto more advanced topics – like Power Meter support.

Power Meter Support:

The Timex Global Trainer includes basic power meter support for ANT+ power meters.  If you’re unfamiliar with Power Meters, I’d suggest checking out my Power Meter Primer Post.  In short, power meters measure how much energy or effort you’re putting into your bike ride.  Unlike metrics pace or speed, which can vary based on terrain – power is an absolute.  Many competitive cyclists and triathletes use power to help pace based on a known threshold.

The Timex Global Trainer supports any ANT+ Power Meter, such as the PowerTap, Quarq Cinqo or SRM.

Quarq Cinqo Power Meter

To pair the power meter, you’ll go back into the same menu system that you configured the speed/cadence sensors within:

Scanning for ANT+ sensors

Once the power meter is scanned, it will automatically display the power information on your Global Trainer.

The Global Trainer displays four power related fields: Power, Power (Avg), Power (Peak), and Power (Zone).  Power is the current power, albeit slightly smoothed at about 6-8s.  This makes it a bit easier to pace by power.  Power (Avg) is actually Lap Average Power, and not ride average power.  This topic came up during my call with the engineering team, where I was a bit confused as to why average wasn’t correctly correlating with my average.  Once they explained that anywhere the watch says ‘avg’, it actually means ‘Lap avg’, then things made sense.  Though, I still maintained they should simply say ‘Lap avg’.

The one piece of functionality that advanced users will note is missing is the ability to calibrate their power meter from the Global Trainer.  When I asked why, the engineering team explained that they felt it was a slippery slope of having potentially having customers believe a given calibration issue lie in Timex’s camp to resolve, versus the manufacturer.  I’d point out that that doesn’t seem to stop any other head unit (actually, all of them), from offering calibration options.  I’d also point out that without said calibration option, it effectively renders the power meter functionality unreliable, as power meter calibration easily fluctuates with something as simple as bringing it outside or indoors.

Finally, I asked about recording interval.  If you look at the Timex Global Trainer files today, you’ll notice that they record at 2-second intervals (listed under Timeoffset, 3rd column from right):

Two Second Recording Rate

However, the default/gold standard for any power meter device is 1-second intervals, which is due to the amount of data lost if you use any higher interval, which in turn creates incorrect numbers for functions like normalized power.  To understand all the implications, read this post by the godfather of power meter analysis (may require joining Wattage Google Group), thus here’s the snippet from Dr. Coggan himself.

Effects on normalized power

The Timex folks responded by saying the limiter to 1s recording was storage space on the unit, which was roughly 20-hours with 2s recording, and thus with 1s recording wouldn’t be enough to finish an Ironman.  This is unfortunate, though not a huge deal killer as you can see above.

On the bright side, during my engineering call, they noted that they are currently planning on adding something akin to TSS to the device, which will be useful.

On the swim:

The Timex Global Trainer is fully waterproofed to 50 meters.  And while I didn’t have any scuba trips planned, I instead went to the bottom of the pool and validated it didn’t die.  It didn’t (nor did I).  Though, I’d suggest that you not routinely go to the bottom of the deep end in races, as it probably won’t help your time any.

Timex Global Trainer in pool

The Global Trainer will record your time information, but if worn on your wrist, will not record your distance during the swim.  This is because like virtually all other GPS devices on the market today, the GPS signal will drop out about 2” below the surface.  As such, it makes tracking rather difficult.

Timex Global Trainer underwater

Of course, you might point out that there’s time during the stroke recovery that the watch is above the surface.  But, the accuracy of those data points is in question, as the watch hasn’t yet re-established, thus no track points are made.  Unlike the Garmin 310XT, Timex has not yet introduced any form of openwater swim mode (which was just recently added in June for the 310XT), though Timex notes they are evaluating their options.

Also note that because it uses 2.4Ghz ANT+ signals between the heart rate strap and the watch, those too don’t work underwater (just like all Garmin Fitness units), only the Polar T-31 coded straps with Polar units will work underwater.  You lose HR signal on the Global Trainer less than 1” away from the HR strap, roughly in line with the Garmin units.

Timex Global Trainer no ANT+ HR

Now, there’s no reason why you still can’t get swim data…if you simply put it in your swim cap. This is what I do to get good distance data about my swims, and it works great.  Just see my detailed post on where to position it.

Timex Global Trainer in Swimcap

Once there, simply hit the start button (big and easy to find), and then be sure to lock the watch (via the enter button for a few seconds).  This will ensure that the cap won’t start pressing buttons.  After which, just swim.

When back on dry land, you’ll find the Global Trainer will make some very nice pretty pictures:

Timex Global Trainer in Swimcap Route

And finally, as a sport watch or timer, it works just fine too in the water, so you can use it to record splits if need be in any wet environment.  Also, one positive aspect to having no quick release system, is there is no fear at all that the watch will fall off.  Once strapped to your wrist, the single-molded-unit is not going to go anywhere.

Timex Global Trainer after a swim

Multi-sport mode:

Multisport mode is utilized when you want to string a series of sports together – such as in a triathlon, where you start in the swim, and then move to bike and run.  This enables you to record each sport individually, but without having to actually stop and reset the watch in between each sport.

Timex Global Trainer Multisport Mode

To get into multisport mode, simply press mode until you see Multisport mode.  It’s easiest to setup multisport mode though via the Computer, which allows you to configure the different views up front, as well as how exactly you want to parse the different activities:

Timex Global Trainer Multisport Config

Once in multisport mode, you utilize the Stop button to advance to the next sport.  This is actually really cool, as it allows you to still utilize the Lap button if you want to mark laps – something the 310XT doesn’t allow.

Once in multisport mode and actually…well..sporting, it will show you the title of the sport on the upper portion of the screen.

After the workout, it’ll automatically splice the three different sports apart (if you choose that way), and display them individually in Training Peaks.

The only challenge with multisport mode is that physically speaking, the watch isn’t designed to easily transition from sport to sport.  Because there is no quick release kit, you have to actually wrap the watch around the bike in transition (or while riding), just like you would around your wrist.  Just something to be aware of.  If you plan to wear it on your wrist the entire event, than this isn’t an issue of course.

Timex Global Trainer in Transition

Review Mode:

Review mode enables you to look back at your history holistically, as well as on a per activity basis.

Timex Global Trainer Review Mode

You can drill down into each individual activity you’ve completed, and get a lap summary, as well as a ride summary:

Timex Global Trainer Activity Review Mode

Even cooler is that you can then go through four pages of summary and average information about either each lap/split – or each activity.

Timex Global Trainer Lap Review ModeTimex Global Trainer Lap Review Mode

Pretty cool on-device historical information, especially if you’ve just finished a ride or run and want to know how things went.

Navigation mode allows you to utilize the Global Trainer for basic navigational functions.  I say ‘basic’, because this isn’t your little car-based Tom-Tom here.  This is pretty much just a digital compass, with a memory on where you’ve been, and where you should be going…all done via Etcha-a-sketch style (like all other competitor devices I should point out).

Timex Global Trainer Navigation Mode

What is cool is that you can drill down into the map view to see exactly where you’ve been:

Timex Global Trainer Map Drawing

And if you’re really lost you can break out the digital compass as well:

Timex Global Trainer Digital Compass

You can also use the ‘Back track’ functionality  to retrace your steps back to the start. And, if you set given waypoints, you can have the device get you back to those as well.

Timex Global Trainer Waypoint Setting

The Global Trainer also supports the ability to create courses using a string of GPS coordinates, but it’s honestly a bit of a pain in the butt to do right now…so I’d wait for that function to get refined a bit more.


When training indoors with the Timex Global Trainer, I’d recommend turning the satellite off.  You can do this via the configure menu.

The reason for this is that while the default Training Peaks software easily handles the fact that you’re actually stationary, some 3rd party suites don’t.  This means that while you may be using a speed sensor on a trainer, your actual GPS speed is still zero – and thus some 3rd party software will incorrectly parse it.

That said, the Global Trainer works great while on a trainer and indoors.  There were some earlier kinks that caused me some data issues in the First Look Review, but those have been resolved with new software updates.

I use the TGT indoors when on a trainer, and combined with the ANT+ speed/cadence sensor, it’ll automatically tell me my distance, speed and cadence.

Timex Global Trainer indoors

Note though that the Global Trainer does NOT support a running footpod – nor any of the ANT+ foot pods available today.  When I asked why (given this is a pretty big item for the winter, or just folks wanting to track running cadence like myself), they explained that when the project first started there were some legal issues with accessing the footpod data stream, and those were only resolved recently.  Unfortunately they were resolved after launch, and thus the following:

“At the time the Global Trainer development began, there were licensing issues that prohibited the use of the foot pod by Timex.  In the last two years, those issues have been resolved, but we could not change the scope of the GT’s sensor capability for launch.”

I still don’t have a good concrete answer as to whether or not this means it’ll never support the sensors.  I’ve traded a bunch of e-mails on the topic with them, and at the moment they’re saying they don’t plan to support foot pods going forward.  Personally, if they don’t have this on the radar to support, this a deal-killer for me and treadmill running.

ANT+ Footpod(Here’s an ANT+ foot pod sensor)

Given the entire point of ANT+ sensors is the ability to pickup data types exactly like this, this seems like a pretty big ‘oops’.

Night Use:

The watch includes a basic backlight, the same Indiglo backlight found on all other Timex branded watches.  While I understand this is the staple of Timex’s watch lineup, it’s also nowhere near as crisp or clear as many of the device high contrast backlights found in other GPS watches today:

Timex Global Trainer backlight

Thus, I’d recommend they look at either ‘refreshing’ the Indiglo…or ditching it.

Using it for other things:

Of course, because it’s a GPS device, it can pretty much record anything, and therefore you can use it for just about everything.  Making it even better is that it’s a simple wrist watch (though slightly large), and completely waterproof.

But sometimes, it is just as simple taking it for a hike, or a wander around the block.  The Global Trainer will happily create maps and routes showing how long, how fast, and how far – as well as wear.

But…it’s always more fun if you go somewhere far away.  Take for example, a few recent flights I did.  In this case, I let it stay on and just record my flight path:

Timex Global Trainer Flight Path Mode

Pretty cool, ehh?  And, on the unit itself, you’ll see the actual speed:

Timex Global Trainer speed while in flight

Of course, you’re imagination at activities is really the limiter here.  In the past, I’ve used GPS devices for Kayaking in the South Pacific, trekking across Egypt, and wandering through Africa.

Battery Life & GPS Reception:

Two areas that have been heavily commented on since my initial First Look review were battery life, and GPS satellite reception.

First up – battery life.  Getting a clear handle on battery life is an incredibly complex subject.  Why?  Well, everything from how many sensors are feeding data into the watch, to how much data is being recorded, to how long it’s been on.  Finally, unless you go out and do a 15-hour activity, you’re likely downloading data in between, thus resulting in at a minimum a small charge.

In my testing I found that the battery charging indicator itself was very inconsistent.  Meaning, one second it would tell me it was at 20%, and then I charge it for 5-10 seconds and now it’s at 40%.  I also found that when using a USB charger, it would never go beyond 90%, whereas with a wall charge it would go to 100%.

Also, the watch supports two ‘standby’ modes, one which displays time – and one which displays nothing.  I generally kept it on display time, because it also displayed battery status.

However, I could never got a solid handle on battery.  Even when I thought it was fully charged, I had it die out on some flights that were just 5 hours.  Yet other times, I was able to leave it recording significantly longer.  I’ve been told that the latest firmware about to be released does include some corrections to the battery meter, so I’ll update this section once I get more detail on that.

Next – Satellite reception and dropouts.  In my initial review, both myself and many others commented on continued satellite reception issues such as inability to get an initial lock on satellites, as well as dropouts during the middle of an activity.

Timex Global Trainer Satellite View

Given the GPS chip in the Timex Global Trainer is the exact same GPS chip as in the Forerunner 310XT – I was curious why the huge difference in reception.  I asked Timex where the chip is located, and they noted directly below the split/start button – which seems like a good location.

I went back to the engineering team on these issues and over the last week they sent over an updated firmware file for the watch, which, based on all my testing thus far – seems to have completely resolved my satellite lock/reception issues.  The satellites lock almost instantly upon turning it on, and they stay locked for my entire activity.

I’ve been told by Timex this updated firmware will be released within the next 3 weeks.

Finally, one last item that continues to be ‘interesting’ is that the Timex Global Trainer seems to be registering about 2.5% ‘short’ for all activities I do, in comparison to the Garmin.  I don’t have a good explanation here – but it’s happening for a number of folks, and in both my case, and theirs, it’s occurring on well measured courses/routes.  As a result, this means that my paces/speeds are actually reporting slower than they really are, which is sorta a bummer.

Timex Engineering doesn’t really have a good answer here yet on this one.  They’ve noted that this is within the ‘acceptable range’ of GPS accuracy – which is indeed true.  But what doesn’t quite jive is how precise it is on every activity I get with being 2.5% short.  Typical GPS inaccuracies would see some activities long, some short, and by varying amounts.  2.5% is too ‘computerized’ a number to be just due to occasional drift.  Hopefully, like the other earlier satellite issues – they’ll work this one out too.


The Timex Global Trainer doesn’t have a wide number of accessories developed by Timex itself for it.  However, because it’s part of the ANT+ ecosystem, there are tons of 3rd party accessories – some ironically enough developed by it’s primary competitor: Garmin.

Timex ANT+ Speed/Cadence Sensor:

As of this writing, this speed/cadence sensor wasn’t available.  It’s apparently just come out in the past few days, and can be bought via customer service for $59.95.  Sorry, I don’t have any further information on it at this time, but I’ve been told it should start trickling out into the normal retail channel over the coming weeks.

Timex ANT+ Heart Rate Strap:

Depending on which bundle you’ve selected, the package will either come with a heart rate strap – or it will require separate purchase.  No worries though, any of the numerous ANT+ heart rate straps on the market today work just fine with the Timex Global Trainer.  Or, you can pickup the Timex branded one (which is identical to others).

Timex Global Trainer ANT+ Heart Rate Strap

This is in theory available from Timex Customer Service also, for $50.

ANT+ Speed/Cadence Sensor:

You can instead (or in the meantime) pickup the standard Garmin GSC-10 Speed/Cadence sensor, which works just fine with it, and is what I used with the bike and Global Trainer.

ANT+ Speed/Cadence Sensor

Instead of costing $60, this is available on Amazon for $35…a much better deal in my opinion.

ANT+ Heart Rate Strap:

In addition to the Timex ANT+ heart rate strap, you can also pickup cheaper variants from Garmin.

The two pictured above are the soft-strap (upper) and classic heart rate straps (lower), available for $40 and $60 from Amazon respectively.

ANT+ Power Meter:

Lastly, for serious cyclists/triathletes, you can purchase an ANT+ power meter from any one of the different power meter vendors out there today, they are:

Saris PowerTap
Quarq Cinqo


The Timex Global Trainer leverages Training Peaks as the core backbone of the analysis software.  This is split into two key different components:

– The device agent installed on your PC
– The website based on Training Peaks

First up though is signing up for an account.  This is completely free, and allows you upload data from your watch to a site for both storage and analysis.  Sign-up only takes a second and is easy and painless.

Timex Training Peaks New Account Creation

Once signed up, you’ll go ahead and install the device agent.  At the moment, it’s only available for PC – but the folks at Training Peaks are very close to getting a version for the Mac as well.  I’m told by the September launch it should be there for general consumption.

Timex Training Peaks Device Agent Install

Once you’ve got the device agent installed, it’s time to get syncing…

Uploading/Syncing Data (device agent):

In order to get data to/from the watch, you’ll need to press mode and change it to PC Sync mode:

Timex Global Trainer PC Sync

From there, the watch is ready to both receive and transmit data.  So, we’ll want to open the device agent:

Timex Global Trainer Device Agent

At this point, you need only to select ‘Download from device’ in order to start the sync process. Once it’s completed downloading the files, it’ll automatically list each activity in the list below:

Timex Global Trainer Device Agent Download

Note that it doesn’t erase the files from the device unless you press the erase button.  This is important because if you fill up the watch (about 20 hours worth of data), then you may get into a situation where you can’t record a new activity.  Though, you can always delete data while on the watch itself in review mode.

The last step is selecting to ‘Save’ the files to the Training Peaks website, which uploads them to your Training Peaks account.  Note that if you already have a Training Peaks account (like I do), you can simply select which account you want from the dropdown, and upload to that account.

Also, it’s from the device agent where you can drill into and change any of the settings pages I’ve discussed throughout the review.  I’ve covered many of them earlier in the post, but for those that I didn’t cover, I’ve created a gallery with every single settings page screenshoted – which you can view here, separated out by tabs and pages in order:

Now that we’ve got the data in Training Peaks, let’s dig into that a bit:

Training Peaks Overview

Training Peaks has long been the standard for online management of sports activity files, in particular, for cycling and running.  Over the past few years they’ve expanded out the number of sports, devices and baseline fitness functions they support.  Thus, when you look at all the options Timex had, leveraging an existing company to provide the underpinnings of the services not only makes a lot of sense for them, but also for us users as well.

Finally, Training Peaks is a great way to collaborate with a coach or team.  This is the primary mechanism I use to upload and receive feedback on workouts that I complete, to my coach.

I’ll walk through each of the main TrainingPeaks.com areas that you’re likely to use.  First up, is the Dashboard.  The Dashboard is where you monitor and manage your day to day existence in Training Peaks.  You can customize any of the different ‘pods’, to best fit what you want to see when you login:

Training Peaks Dashboard

The only slight bummer here is that many of the cooler pods are only available in the Premium version, which has a cost associated with it.  For example, I normally use the Premium version – and you can see the pretty big difference:

Training Peaks Dashboard (Premium)

Next up is the calendar tab.  This is the area I actually use most, as it helps me to track all the workouts I complete.  I can customize how each workout appears in the calendar.  Below it the default view:

Training Peaks Calendar

And here’s the view I use in my primary Training Peaks account that I’ve had for years:

Training Peaks Calendar

Now we’ll drill into a given activity, such as a recent bike ride I had.  As you can see, on the main page I have information that’s summary in nature, with the again customizable pods to easily change and breakout information dependent on what I want to see:

Training Peaks Activity View

Next, if you click on the Maps and Graphs area, you can see a map of the activity, as well as a graph of my actual workout with the different ANT+ data streams charted (Power, Cadence, Heart Rate and then GPS provided Speed/Distance/Elevation).  Also, you’re able to hide any metrics you’d like along the top bar:

Training Peaks Activity Map-Graph View

Now, Training Peaks uses MayQuest maps by default…which..aren’t necessarily the best out on there whole wide internets.  So they’ve handily provided the ability to simply view your track in Google Maps as well via a quick dropdown menu:

Training Peaks Export Activity

Google Earth Activity View

Finally – my favorite feature in Training Peaks is the ability to see ‘Bests’ divided up by different time chunks.  For example, my best power output, or my best pace:

Training Peaks Bests Graph/Split Mode

But Training Peaks isn’t just about looking at any given activity – it’s also about analyzing how you as an individual may be fairing.  For example, via the Withings WiFi Scale I can automatically import weight measurements straight into Training Peaks.  You can also modify these values, along with the others in the box below, manually.

Training Peaks Daily Metrics

Also, I can go ahead manage a daily food log with a pretty big database of foods, occasionally I do this if I want to lose a few pounds…

Training Peaks Food Library

Recently (just last week) they added TSS/IF and PMC functionality.  TSS is Training Stress Score, and is a way to visualize and manage your training load, and is a great way to try and nail the perfect taper before a big race.  You can read in depth about these functions here.  Though this isn’t available in the free Timex version, you can see some of the options available in the subscription Training Peaks version.

Training Peaks PMC PodTraining Peaks TSS/IF Pod

Finally, some folks will note that Training Peaks is freely accessible to any user – without buying a Global Trainer – and that’s absolutely correct.  In fact, there are two levels of Training Peaks access.  The first is the free level, which includes basic functionality.  And the second level is the Premium version, which includes advanced functionality primarily targeted at more advanced users.  Here’s a little chart showing the differences. The Timex variant fits in the middle a bit, which contains specific enhancements not available in the basic version.

Also, note that if you already have a Training Peaks account, you can just download the updated device agent software and link it to your existing Training Peaks account – which is what I do for my day to day training log.  Works great!

And same goes if you have other training devices from other vendors – they all seamlessly integrate into TP.  For me, it’s my one-stop-shop training log.

If you’d like to look around at exactly what’s offered – I’ve shared a few workouts from within Training Peaks for you to play with.  Which…reminds me – that’s yet another cool feature of TP – the ability to share workouts!

– Swim
– Bike Ride
– Run

Here’s how you can share them across a variety of mediums:

Training Peaks Social Networking Sharing

Updating the Firmware

Through the Training Peaks device agent software, you can fairly easily update the firmware on the Timex Global Trainer.  This is important as new updates come out and you want to get either new functionality, or bug fixes for the TGT.

Timex Global Trainer Firmware Update Part ITimex Global Trainer Firmware Update Part IIITimex Global Trainer Firmware Update Part IV

The whole firmware update process only takes a minute or two at most, and best of all – you can export and save all of your configuration settings, so you’ll be quickly back up and running – something that Garmin doesn’t provide for with their watches during some firmware updates.

3rd Party Software:

At this time, there are no 3rd parties that support the Timex Global Trainer.  The good news though is that the Timex Global Trainer creates simple XML-based files within the Training Peaks folder structure, which could easily be parsed by 3rd parties:

Timex Global Trainer PWX Files

For fun though, here’s a quick look inside the file structure:

Timex Global Trainer PWX Files Insides

I’ve talked with the founder and lead developer of Sport Tracks and he’s looking into what it will take to add Global Trainer support to Sport Tracks 3.0 (which is just entering beta).  If you’re interested in having Global Trainer support, please let him/them know via their forums.


In summary, I think the Timex Global Trainer is a great new entrant to the market.  Even though the product is a first generation device for Timex, I think they’ve hit the mark in almost every category.  Based on my in depth discussions with the development/engineering team – I think they understand the areas they need to address – and can largely do so with simple firmware updates.  Between the Timex team and the Training Peaks team they are one of the most receptive athletic watch companies I’ve talked about new features with.

Further, based on the private firmware updates I was provided over the previous weekend, I think they are indeed making good on fixing some of the issues that were outstanding, and those updates should be making their way to your hot little hands in the next three weeks – just in time for the full retail availability launch in September.

Here’s a quick breakdown of what I see as the Pro’s and Con’s of the Global Trainer are:

Things I like:

– Highly customizable, everything is tweakable…everything.
– Leverages TrainingPeaks.com as data repository
– Ability to export/import all settings to a simple savable file on your computer
– Fully waterproof to 50 meters
– Multisport mode allows one to still utilize ‘Lap’ functionality (small, I know, but really nice!)
– Smoothing of run paces helps to minimize typical GPS speed fluctuations
– Same form and size as all other multisport GPS watches
– Only one unit – no separate GPS dongle/attachment required

Things that could use some improvement:

– No footpod support is a huge bummer for treadmill users
– Lack of power meter calibration makes it less than ideal for power meter users
– Backlight isn’t as bright as most competitors
– Some of the user interface could be smoothed out a bit

Review LinkLinkLinkLinkLinkLink

Finally…I take a lot of pictures during the review process.  I took over 500 pictures for this review.  It seems to me it’d be a shame to let them sit forever on my little home server, thus, I’ve picked out a fair ton of them and put them all in an album for you to browse through.

One last thing…if you’re looking for all the official information links – here they are (all PDF files):

Quick Start Guide
Full Manual (Other languages here)
Marketing Leaflet
Spec Sheet
FAQ Sheet
Bike Sensor Manual (actual product not available yet)

Finally, if you found this review useful – you can support future reviews by simply using the links below to pickup the Global Trainer.  Given pretty much everything is cheapest on Amazon or one of their sub-vendors anyway, it’s what I usually use.  By doing so, I get a small credit back for anything ya pickup there – which helps find purchasing new devices and device giveaways.

The reviews generally take 20-40 hours to put together, so it’s a fair bit of work (and labor of love).  Also, as you probably noticed by looking below, I take time to answer all the questions posted in the comments – and there’s a lot of details in there as well.  So if you found this review helpful in your purchasing decision, you can support future reviews like this by using any of the Amazon links (accessories or the units themselves).   As noted earlier, there are two versions available of the Timex Global Trainer– one without the HR strap, and one with the Premium HR strap.

As you’ve seen throughout the review there are numerous compatible accessories for the unit. I’ve consolidated them all into the below chart, with additional information (full posts) available on some of the accessories to the far right. Also, everything here is verified by me – so if it’s on the list, you’ll know it’ll work. And as you can see, I mix and match accessories based on compatibility – so if a compatible accessory is available at a lower price below, you can grab that instead.

  1. i guess Timex did a great entry with that one, except that Garmin Forerunner 310xt gives much more, i guess ill stick to garmin (i’ve lost my gf305 battery failure only)

    thanks man!

  2. It’s finally here!! Skimming it now, can’t wait to read the whole thing. I just bought a Polar RS800CX, but am now having 2nd thoughts because of it’s problematic interaction with SportTracks.

  3. I’m disappointed. I really wish Timex nailed the basics like battery life and distance accuracy before releasing this watch.

    I guess I’ll buy a Garmin and see what Timex has in a few years.

    Thank you so much for the review.

  4. 1 – No footpod for treadmill running. HUGE oversight IMO and a deal killer for me.

    2 – Maybe I missed it but it appears there is no ‘quick release’ style kit to go from a wrist mount to a bike mount. Definitely would be a step back to not have this.

    Seems nice but I’m still a little disppointed overall.

  5. excellent review (as usual). i am still undecided and may wait for garmin’s next revision to the 310xt.

  6. Awesome Review. I purchased the watch last week. So far i’m liking it. 2 things i’ve encountered.

    1- watch shuts off after inactivity of 30mins. I like to get my gps signal way in advance before a race so its something I don’t have to think about. Found about the ‘auto shut off’ at the start of my race..

    2-watch went totally dead on me. it was non responsive to charging. I ended up pressing all buttons at same time and ended up turning back on – nothing noted in manual about reseting the watch

  7. Great job on the review. You are truly a resource that I consult before a purchase and recommend to friends. Keep up the great work.

  8. great review… i too was a little disappointed not to see a footpod, or a quick release kit… id hate to have to strap it on to my bike and then off of my bike during transitions… garmin still seems to have a leg-up on them.

  9. Awesome review! I’ve been thinking about getting a GPS-based watch and this would give me something to think about, provided that they do come out with a Mac version later this year.

  10. Does any buddy know if the training peaks software allows you to track your shoes? That is the one think that I like to keep track of.



  11. Excellent Review Ray! If only you were running Garmin or Timex the Tri word could probably have the perfect watch!

    If you don’t mind I am going to post this link over at my blog — Just a great review!

  12. Ok, I am skimming this post only because too much technology causes my brain to seize up and all I can think about then is puppies and Hello Kitty.

    Question: (probably answered in the post) Is the Timex only good with Windows or will it work with a Mac?

  13. Anonymous

    There were no references in the review to calorie burning estimates.

    Does the unit estimate calories burned and can it be programmed with your specific energy output at different heart rate zones without investment in a New Leaf profile or the like?

  14. Timmy P

    Ray – top notch review – im beginning to take these for granted as I know whats coming – FULL BLOWN REVIEW. 310 XT is still King in my books – next update to it in the Spring 2011? one can only hope for a new Race season.

  15. Hi Cavin-

    RE: Shutting off after inactivity time

    Yes, that’s a good point and painfully annoying – especially if in transition.

    RE: Reset buttons

    Interesting, I haven’t seen that yet – but good to know about the ‘Hold everything and hope it works’ solution. 🙂


    RE: Mac Version

    It’s close…very very close. 🙂 By September at latest.

    Hi Anon-

    RE: Calories

    You can set calorie burn levels based on a few bulk categoires – but you can’t pull in any new leaf profiles. Page 6 on the full manual has a bit more information about it as well.

    Thanks all!

  16. Your review is thorough as always.

    Forgive me if I missed this in all the great stuff you wrote, but can I set intervals with specific speeds or HR based on time or distance? Some workouts require that I use time, and others have me using distance when running.

    Also, I use WKO+ and it has been updated to accept Global Trainer data.

  17. Anonymous

    Do you know of any way to show split/lap distance in-workout? This seems to be a huge oversight. Obviously it tracks distance per lap since it shows up in the workout review, but I haven’t found a display window to show current distance per lap.

  18. Shawn

    Do you think that adding footpod compatibility could come down the road as a firmware update?

    I really like everything else about this watch, but I run a lot on the treadmill and never having that support could sway me to purchasing the Garmin 310XT instead.

    Thanks for such an in-depth review!

    How does the battery last in the the Day-to-day watch mode?
    Can you use, say, a regular countdown timer (as a kitchen timer) when it’s like that? Or would a 20-hour timer blow out the battery?

  20. Great review! I’ve used almost every watch on your rolling pin and returned them all except for this one….although I’m considering it based on the fact that for 2 days in a row now, standing outside at 5:50am in the pitch black dark, just standing there — for at least 5 mintues each time, I could never lock on a Satellite and eventually started my daily 5 mile run without it. Of course when I stopped at a red light with .5 mile to go, it locked and recorded my last little bit. I am a female with VERY TINY wrists (much like your girlfriend) and while the watch does look like a bit of a joke on a woman’s wrist, I like it way better than any of the Garmin models (that is when it actually locks on a satellite).

    So when will the firmware be released with the update? I’m afraid to turn my watch off right now for fear of losing connection to a satellite. 5 mintues to wait to connect, and then still not connecting, is just not okay. Especially before 6:00am.

  21. Hey there,

    Cavin again… noticed a few other things..

    -its been working out great in the water on my wrist.. calculating the distance which is nice.

    -the downside to having it on your wrist during swim is you have to be careful when taking off wetsuit you aren’t accidentally pushing any buttons…somehow after my open water swim yesterday(in performance mode)while i was taking off my wetsuit it switched into ‘multisport’ mode…so now I have a bunch of useless 3sec laps.
    called timex tech support no way to delete these laps on the watch or in trainingpeaks. Hope this will come down in an update.

  22. I do a lot of trail running and was wondering what/if any testing you did with this watch on trails.



  23. Anonymous

    Very nice reviews, stories and tips. I am new to multisport competition and your reviews helped my pick out the GPS watch that fit my style. I have bookmarked your site and visit often. Thank you for such a great page.

    3 entries: Coment, Facebook, twitter.



  24. I’m confused as to what to buy whether the Polar rs800cx or the garmin310xt because everytime I open your blog dc rainmaker I’m always convinced by your Gamin 310xt!

  25. I know that’s not the main use of the watch – still, can you give any more details on the day-to-day watch mode?
    is it possible to set alarms there (wake-up), can you use a time/stop-watch function without fully powering up the watch?
    and what about battery running time in “normal” watch mode?
    and, last but not least – when in wathc mode, the GT doesn’t switch itself off after 30minutes, right?

  26. Hey Ray,

    Great review and for the 310XT. I wanted your personal opinion. So I recently bought the TGT and unforuately after updating it with the firmware. I have had problems where it seems to consistanly under report my miles by 0.2 only when I bike. I suspect it may be losing signal alot, which is odd since it works well when I run. Anyways I did return to REI and I either can get a replacement or go with the 310XT. I think from a aesthetic viewpoint, the TGT is nice but means nothing if it can’t perform. I have read your review on the 310XT. If you had to choice one or the other what would you go with and why. Any input would be great!


  27. Wow! Thanks for all the information!! You are the BEST!!

  28. Hi Al-

    RE: Intervals

    I need to double check on this one when I get back home, as I don’t have the watch with me on this trip at the moment. Sorry!

    Hi Anon-

    RE: Lap/Split distnace in workout

    This is actually an item I brought to the development team as I want it as well. I’ve been told it’s something they’re looking at.

    Hi Shawn-

    RE: Footpod compatibility

    The Timex folks can absolutely add it via firmware, it’s just a matter of them doing it (they’d be wise to though as it’s one of the major items keeping me from fully recommending the watch over the 310XT).

    Hi Anon-

    RE: Battery during day to day mode

    For me it lasted quite a while, the manual says 12 days though in standby mode.

    Hi Alex-

    RE: Firmware update

    I’ve been told no more than three weeks from when I published, so I suspect within the next 7 days. Good news indeed!

    Hi Cavin-

    Good points!

    Hi Jeremy-

    RE: Trails/offroads

    Yup, I did a fair bit on local trails and offroad while running mostly and had no issues. It uses the same GPS chipset at the 310XT and I’ve used that all over creation in the woods without problem.

    Hi Kip-


    Hi Runner-

    Go with the 310XT (or TGT) over the Polar, just having everything in one device is worth it.

    Hi Stetre-

    RE: Day to day mod

    Yup, you can set alarms for waking up, and also use a simple stop watch mode if you’d like. As well as setting time based alarm. Battery time in normal ‘watch’ mode is 12 days. And yes, when not in watch mode it does switch itself off after a period of time (I think it’s 10 minutes, but I haven’t quite timed it). It’s quite annoying thoug, so I’m hoping that change/fix that in an update.

    Hi David-

    RE: 310XT or TGT

    At the moment, I’d go with the 310XT – due to the lack of foot pod support primarily, and the lesser power meter features. Those can all change via firmware and I’m optimistic that they will.

    Hi Sara-


  29. Hi Ray,
    thanks for re-commenting/answering.

    “And yes, when not in watch mode it does switch itself off after a period of time (I think it’s 10 minutes, but I haven’t quite timed it). It’s quite annoying thoug, so I’m hoping that change/fix that in an update.”

    yes this can be annoying, but I guess it only switches itself off if there’s no data coming > so when you’re not running, swimming, cycling,hiking,…

    it’s still annoying, but it probably helps keeping the battery alive for just a bit longer.

    I had a Suunto X10 (GPS watch, but not really for training, more hiking) and there you had the problem that the watch didn’t switch itself off when you weren’t doing anything > you were on y summit, taking a break and the GPS module/watch kept on running, not really getting any data > battery drain…

    just waiting for the official overseas release of the TGT, shouldn’t be long…

    I am searching for a good multi-functional watch.

    I am not an athlete however, but an avid traveller, walking long distances nas well as riding in a car. My needs therefore are somewhat different, but it seems this watch (Timex) maybe good for me?

    Functions I need: time (prefferably multi-timezone), date, weekday, compass (prefferably one working not only when watch moves), GPS, thermometer, barometer, speedometer, distance meter, GPS coordinates output, prefferably history (e.g. 24 hours) of important meters (pressure, GPS-based positions), alarm, stop time, long battery life (I’d be using is it as my prime watch).

    Less important though useful functions include calory-burning meter, heart rate monitor, internet-based outside weather and othe rthings a traveller would need to know better where he travels and about the current location.

    However, battery life kind of puts me down. Right now I use Casio Protrek which has thermometer, barometer, altimiter (which is unfortunately working only on air pressure), compass, 5 alarms, stoptime, watch, date, weekday functions, as well as showing 12 hour history of pressure. It uses 4 batteries with lifetime of 1,5 years, therefore recharging is not an issue. It would be good if something similar would be with new watch as I plan to use the watch constantly as my main watch (as I do use Casio now). Or is the battery life longer if you don’t constantly use various functions?

    What watch could you suggest me?

  31. Reost – I haven’t tested the TGT yet, as it’s not yet available in Europe, but from what you write I would go with the Suunto X10.

    It has everything you ask for and is, in my eys, better suited for you as you don’t need all the training features the TGT offers.

    Also, if i am not completely mistaken, the TGT doesn’t have the barometer feature but gives you altitude (and speed, distance,…) only via GPS.

    battery time of the X10 is pretty good, when used as watch and even if you use the GPS you can still get 15-20hrs.

    Very informational review.

    I have been using the TGT for around 3 weeks now and i have a couple points for your consideration.

    When you review the alerts you mention the lack of a time alert.

    Quote: “You can configure alerts for many different areas, such as Distance, Heart Rate, Power, Speed/Pace, Cadence, and Altitude. Though interestingly missing is ‘time’. For example, the ability to create a recurring time alert every 10 minutes reminding you to drink water.”

    Couldn’t you use the interval/countdown timers set on a repeat for that sort of info. This is what i do. Also you can rename the interval/countdown timers through the device agent to be called “Drink” or “Eat”.

    Only dis-advantage to this i find is you have to use one of your screen sections to display the timer.

    Also in your comparison chart against the 305 and 310 on the workout section you state the TGT as “basic intervals only”

    I think this could be the only thing you didnt cover in the review.

    In my opinion 5 Workouts each with 20 intervals that are all linked to HR Zones and double up as countdown timers is fairly advanced.

    And for those who dont want to set up there own session there is a list of presets available to choose from within the device agent.

    Still i learnt alot from your review. Especially about the training peaks side of things.

    Impressively thorough review! Still, I have a few questions 😉

    Kayaking will be the main use for me, which only leaves this and the 310XT as they are the only fully waterproof GPS watches.

    From a purely visual standpoint the Timex LOOKS much more durable than the Garmin. I would also trust Timex more in this area since they have extensive experience with sports watches. I have only seen the 310XT in person – what is your take on the ruggedness of the two watches?

    Your two main critisisms – no footpod and no power meter calibration is of no relevance to me. Which would you choose then?

    The display on the Garmin looks from your pictures to be a bit more easily legible – is this the case in real life? Can the Timex also show 1, 2, 3 or 4 data fields and if so, does 3 look like Garmin with one large on top and two smaller below? I don’t see a picture of this.

    Thank you very much

    Jesper, Denmark

    V. Nice review. Had a few questions…
    1st. I was hoping you’d do a test run of the navigation feature. I couldn’t get a handle on how well it worked. Specifically, does the TGT have the capacity to plan a route & cue one to go North/South/… at a certain point, which would correlate w/ a turn on a road or trail (or… waterway for those kayakers out there)?

    2. Someone commented on the durability TGT v. Garmin 310xt. While at a store today, I saw a returned 310xt w/ a cracked screen. Could you lend any insight?

    3. Footpod…seems to be a deal breaker for some. Could you weigh in on the importance of this. I could see the importance of cadence, but I can do that in my head v. easily. As well, the treadmill can record the distance run fairly well. Your thoughts on weighing the need for a decision b/t the TGT & 310xt?

    4. How inaccurate would a power meter be without calibration?

    Greatly appreciate your insight.

  35. I have the 310XT, and I love it… except for the premium HR. Every time my shirt gets soaked (~50 min running) the HR gets crazy. Tried all you can think, moved around, put on the side, back, no luck.
    Question: is the TGT HR monitor any better? I’m wondering if I should buy the Timex HR Strap.
    Note: the standard strap from Garmin work much better for me, but it isn’t waterproof.


  36. Hi Reost-

    RE: Watch wanted

    Unfortunately, the features you want (specifically multi-time zone and thermometer and week day) aren’t in any GPS sports watch out there on the market today that I’m aware of (at least mainstream ones).

    Therm is in the Edge 500/800, but those are cycling. I’d agree with stetre76 in that the watch that you’re looking for probably isn’t a fitness one, but rather one suited more towards hikers/adventurers. Sorry!

    Hi Marc-

    All great points. In reference to intervals, the ability to do highly customizable intervals such as with GTC or on the Garmin devices isn’t quite there (including speed/power/pace/HR/time targets). I think it could be – just a matter of firmware updates. But agree with all your items.

    Hi Anon-

    RE: Durability

    Yes, the Timex is definitely more durable than the 310XT from a droppage standpoint. The 310XT does suffer from folks dropping it on it’s face and cracking. 🙁

    Given you don’t need either foot pod or power, then the Timex may indeed be a good choice for you.

    RE: Timex data fields

    Yes, like the Garmin, if three fields are choosen, the top field is larger.

    Hi James-

    RE: Navigation feature

    It can plan a route based on GPS coordinates, but not a routable one. I’ll try and add some detail to that section this week.

    RE: 310XT cracked screens

    Yes, it’s an issue. There’s no raised bezel – so if dropped exactly on it’s face on concrete, it can crack. Rare, but happens.

    RE: Foot pod

    Personally, I think it’s important – but I understand not everyone trains with one.

    4) Inaccuracy

    It can vary, but generally in the range of 10-15%

    Hi Hans-

    RE: TGT HR Monitor better

    No, it’s identical.

    See my new post on the Polar variant solution though:

    link to dcrainmaker.com

    Also note that the new Edge 800 HR strap seems to also fix the problem (looks identical to Polar).

    Thanks all!

  37. Excellent Review.
    Thank you so much for the review.

    One question if i can.
    Is it possible for TGT to set distance for Auto Lap for bike and Run separately?

    I tried to do that . but Icould not.
    I found that it is possible for 310TX


  38. Hi there,

    Enjoyed reading your reviews massively. Helped me make my purchase of the Timex Global Trainer. I have used it a couple of times so far, and I think its a good product.

    Was wondering if you’ve had a chance to use the Timex Speed/Cadence Sensor as well? I got it together with my Global Trainer. I’m sure I followed the setup instructions properly.

    However, at first I couldn’t get the cadence but I got the speed, the next time I tweaked the cadence sensor to be nearer the magnet, and voila, managed to get the cadence readings. Then the speed readings stopped.

    Any idea why this might happen? Also, do you know how I can contact Timex support for help?


  39. JTalike

    Great and helpful review
    I have been struggling between the 310Xt and polar rs0800cx.
    I have been a long time polar user but they are behind on the GPS, i.e. separate device to wear, etc.
    I like the smoothing feature you describe on the TGT. If treadmill and power features are not important, would you choose the TGT over the 310XT? The remaining concern is the interval edge of the 310?
    I am an avid marathoner and becoming more accomplished as a cyclist with a half ironman being planned. Thanks!!!

  40. Very helpful review! I still love the concept. I got the Garmin 405 before the release. Bummer about the footpod so I think I made the right choice. Hopefully by the time I’m doing the Ironman, they’ll have a better version.

  41. orded the TGT yesterday and looking forward to get it (somewhen next week). gonna mainly use it for hiking (Alps) and cycling (Road and MTB) > so i wonder if it’s going to work with my Ant+ senders from my VDO Z3 cycling computer….

  42. Since you have thoroughly tested both of them, which one would you recommend, the timex Global trainer or the Garmin 310xt? Specifically, what is your opinion about their GPS sections?

  43. Anonymous

    Hi there,

    Great review! Question though – you indicate some ‘cheaper’ versions of the Garmin HR monitors will work with this.

    When clicking on the links (both the soft straps and hard straps) in the post, I don’t see that they are ANT+ – are you sure that these ‘cheaper’ versions work with the TGT?


  44. Hi Jiro-

    RE: Auto Lap for run/bike seperately

    No, it’s one and the same setting.

    Hi YawWei-

    RE: Timex Speed/Cadence Sensor

    I haven’t tried the Timex variant quite yet, though I have tried identical ones OEM’d by a few others. The magnet isn’t quite as nice as the Garmin ones, and requires it to be a touch closer. But, by the same token, being two seperated components, it does give you more fleixbility.

    Hi JTaLike & Federico

    RE: TGT over 310XT or 310XT over TGT

    I think in general the 310XT is more polished than the TGT, but the TGT shows more long term promise. It’s a tough one, but I personally love the 310XT.

    Hi SteTre76-

    RE: ANT+ Sensors from VDO Z3

    It depends on how those sensors are broadcasting themselves. If they announce themselves as a speed sensor, cadence sensor, or combo speed/cadence sensor – then you’re good to go!

    Hi Anon-

    RE: Garmin HR Straps

    Yes, I’ve tested all of these. I have all of the Garmin variants here and all of them work just fine without any issue.

    Thanks all!

  45. David Clover

    Wonderful Review! This is the first time I have been to your site – and I found it very helpful.
    Does the Navigation mode display real time coordinates, so that I could use it in Geocaching?

  46. Hated to do it, but I took my Global Trainer back to REI today and grabbed the 310xt. I really wanted the TGT to be THE watch. The battery life definitely was not doing it for me. On top of that, it missed half of my run today (GPS). Frustrating.

    I do think some day that watch will be killer, but I need something now.

  47. Hi Ray,
    as you seem to know some peopleat Timex – is there anywhere where you can read about the changes done to the firmware (changelog) – would be nice to know what’s “new” with the new 2.84 firmware – couldn’t find anything at the Timex website.

  48. sorry for having another question – but is there a way to get to a gpx file from the global trainer? the gwx files you get from the device agent are not really satisfying, as the Training Peaks software is not really nice to use.

    any chance to get to a gpx or even klm file directly? or is there another possibility to extract the data and NOT have to use the device agent software?

  49. Bernard Maughan

    Thanks for a great review.

    For the A types out there, I have set the main question I’m asking in bold below, and for the rest of us, my feedback on the Timex Ironman GPS Global Trainer (TGT) and this site follows.

    I bought my TGT at the Expo at the Chicago Triathlon (literally! I was the last one at the Timex stand on the last day and walked away with the display model, the Speed/Cadence sensor, and an older version of the HR strap and a Headsweats Timex logo cap compliments of the guy running the stand – all for a significant discount to the MSRP (sweet!)…and as promised, I received the latest 2.4ghz soft HR strap/transmitter by courier when I returned home to Singapore.

    In the meantime, I found your blog and review, and have enjoyed reading many of your reviews and race reports in the last 2 weeks.

    Since Chicago I’ve had fun using the TGT for logging basic training rides and runs, and am generally impressed at it’s intuitive menus and ease of use (I also have the Polar 625x, Suunto T6C and Powertap/Cervo).

    This morning my program required me to do an interval indoor trainer session on the bike and I used the Suunto as I know how to set it up for this particular workout.

    Later, I started playing with the TGT to see how I would set it up for the same workout, but have got stuck as the documentation doesn’t adequately explain the timer functions for intervals and I think that this workout may need to be run across different timers.

    The workout was:
    Warm up 10 min easy
    Prep 5 x (30 sec very hard, 30 sec easy)
    MS 8 x (4 min hard, 2 min easy)
    Cool down 10 min easy

    Can you shed some light on how I would run this kind of interval workout on the TGT?

    Thanks again for a great site and congrats on your deal with Slowtwitch – that’s awesome!


  50. Hi, Thanks for the review. It definitely helped me decide to purchase the TGT. Have you heard any news from the Timex folks about improving support for navigation with better importing of waypoints and routes?

    Also, the guys over at SportsTracker are working to implement support for the TGT (link to sourceforge.net). They could use some PWX files with cadence/speed/power data to use for testing. Please check out their forum if you’re interested in sharing.

  51. I am about ready to give up on the TGT. I am still experiencing fairly large GPS inaccuracies. Last week I ran the same course 2 days in a row. First day it read 4.95 miles second day 4.75 miles. Then I ran a marked 12 mile course and the TGT said it was 11.61.
    On top of that the speed data on training peaks does not seem to be correct. For example I ran the “11.61” miles at 6:53 pace but my best 10 minutes was at 6:54, 20 minutes at 7:06 pace, 30 minutes at 7:18 pace, and 60 minutes at 7:36 pace.
    Am I doing something wrong? What is up with these numbers?

  52. Bernard Maughan

    Ray, while you’re busy in Seattle and at Interbike I figured out how to program the Interval Workout I posted in my last comment.

    It’s actually pretty easy, but tedious. You can do it either in the watch or on the pc as you mentioned in your review. I started on the watch, and finished in the settings area of the Device Agent software.

    I decided to edit Timer 1 and called it 4x4MMP (the MS is 4 x 4minutes at Mean Maintainable Power). Next, I set the timer to “Interval”.

    Then I had to add up the total number of intervals (effort and rest) and set the number of intervals at 19.

    Next I set Interval 1 at 10 min, Zone 1, interval 2 at 30 sec, Zone 4, interval 3 at 30 sec, zone 2 etc until I finished the prep intervals. (Actually, this is a power workout, so HR zones are going to be meaningless especially in this set since my HR won’t come down fast enough in each 30 sec rest interval during the prep phase, but I used the zones to illustrate the point). After that I set the MS intervals accordingly, 4 min zone 3, 2 min zone 2, for each effort and recovery interval, and finally set interval 19 at 10 mins, zone 1 as the cool down.

    I can see it will take a while to completely figure out the uses and easiest ways to program the TGT and I look forward to any other tips you post on using it.


  53. I’m having serious issues with my TGT finding satelites. My buddy has the Garmin 110 and gets satelites 2-3 minutes before I get a lock. Any tips/suggestions?
    link to triwithrecklessabandon.blogspot.com

  54. Jeffrey which firmware are you using, did you update to the lastest 2.84 version?
    I only got my TGT last week, but so far I am really, really happy with the GPS reception.
    I am living in Austria, and on first use, it took the TGT some 90-120 seconds to get a fix.

    Then, I took it on a business trip with me, to Nantes, France (some 1.200km (750miles) from Innsbruck) and it took the TGT less than a minute to get a Sat fix.

    Back in Innsbruck, the TGT hat a Sat fix in approx 30 seconds.

    With a Suunto X10, which I’ve previously owned, the Sat fixes would have taken far longer > TGT GPS reception is excellent.

  55. Jawn

    Not having a vibrate sensor alert is the deal-breaker for me. I can only hear out of one ear, witha all the other background noises, I can never hear my device, but I always like to know what my mile splits are during a run.

    Also, constantly being 2.5% off on the GPS Distance accuracy is ridiculous! Get it right Timex…THEN release a product that works!

    Great review. I think I’ll stick with my 305 & 310. Thank you much!

  56. Kev

    Great review. which I think has answered my question, but please can you confirm from your experience….

    Would the Ironman GPS would work for events in excess of 20 hours, with an appropriate mid-event recharging strategy?

    Does the timex continue to operate and record whilst charging, or does it switch off?

    Is the maximum recording capacity of 20 hours at 2 seconds its finite capacity, or can a lower data recording resolution be selected to allow to run for events longer than 20 hours.

    I have developed a technqiue for charging my 310XT whilst running – the device keeps running and recording data, and has sufficent memory to run beyond 20hours at high resolution. On face value it looks like the Timex will not accommodate such actitivites, but I would welcome your views.


  57. Well Jawn, when the 310XT was released there was still some bugs in it. It is hard to have a perfect firmware right of the bat, because you can’t fully test real world conditions without releasing it to the public.

    That’s why it is very easy to update the firmware.

  58. Anonymous

    Great review. My major concern is battery life – it needs to be able to hold GPS signal, track accurate distances for a minimum of 12-14hrs and record all data if I’m going to use it for a full Ironman race. Has anyone used it yet in a full IM race anf can confirm that it does work as advertised?

  59. Anonymous

    Great review. Timex should print this off and ship it with the watch as a manual! I was wondering if anyone had tried that setup with the GSC-10 Cadence/Speed sensor from Garmin. I understand that you have to disable the GPS to get it to work, but then I don’t seem to record Distance anymore either…I’ve set the sensors to Heartrate>SCAN and SPEED/CADENCE>SCAN.The rest is set to NO.Is that correct or shoudl SPEED/CADENCE be set to ‘SPC’?
    Is it possible to still get ‘Distance’ when just dealing with the speed/cadence sensor (and obviously the watch)?

  60. Rainmaker, I now use a Garmin 305 will my heart rate monitor work with the Timex?

  61. Hi David-

    RE: Coordinate displays

    Yes, the coordinates are indeed displayed. I believe I have a picture of that mode in the gallery.

    Hi Stetre76-

    RE: GPX files

    I’ll ask next time I chat with them.

    RE: Not using Device Agent

    During my recent discussions with them at Interbike, they were pretty clear that the device agent will be the only interface to the device. But that 3rd parties could build on the files being exported one they provide better docs (Timex).

    Hi Greg-

    Re: Bests

    Hmm, that’s strange. Have you talked to the Training Peaks support folks and asked? In my experiance the TP guys are more than willing to figure out where the bug is and fix it.

    RE: Workouts

    Thanks for circling back and posting that – definitely appreciate it! And I know others will as well!

    Hi Jeff-

    RE: 2-3 minutes to lock

    That sounds rather odd – are you on the latest firmware? As Stetre noted, this was fixed in the most recent firmware.

    Hi Jawn-

    RE: Vibrate sensor

    The only reason they didn’t include one was to cut costs. I wouldn’t be surprised however if it’s being looked at for the new version.

    Hi Kev-

    RE: Mid-charing

    The max recording time is really the primary issue. Unfortunately, you can’t change the recording resolution. I’ll ping the Timex guys and see if they have any ideas on that one.

    Hi Anon-

    Re: Folks using it in full IM races

    I’ve seen a number of folks use them in full IM races without issue over the past few months. So I think you’re good there (also, the product lead that I talked to at Timex did IM St. George with his…fwiw).

    Hi Anon-

    RE: GSC-10 speed/cadence

    Yup, in fact, as noted, this entire review was using the GSC-10. 🙂

    However, it has to be SPC, and not just speed or cadence since those are different ANT+ Device profile types (and differnt ensor types). It sounds like perhaps the speed sensor portion isn’t working. I’ve broken a few GSC-10’s and seen it where the cadence will work, but speed won’t – and vice versa.

    Hi Roland-

    RE: Garmim HR strap

    Yup, the Garmin HR strap is ANT+ and thus will work just fine with the Timex. About half of the time I spent using the Garmin strap, and the other half the Timex strap.

    Thanks all!

  62. Bernard Maughan

    Ray, still loving the blog – thanks. I used my TGT last weekend in a half iron distance race – well tried to. I did a swim/bike/run workout the day before the race to get used to the course elements like swim exit, transition and road surfaces and test the TGT in multisport mode for the first time.

    It worked well, except that I found it intuitive to click the start/split button at the end of the swim instead of the dwn/stp/rst button, but I saw that it had only created a split time and hadn’t shown the “Transition” message so I pretty quickly worked out I had hit the wrong button, and clicked the dwn/stp/rst button to get the desired result.

    The next day with all that was going on before the race, I somehow changed the mode from Multisport to Performance without realising it. I clicked on start/split at the beginning of the swim and dwn/stp/rst at the end of the swim and again as I was exiting T1 but was too preoccupied with racing to look at my TGT to see what it was doing until well into the first 30km on the bike. I noticed that it was in performance mode and tried to change back to Multisport mode and got an error message saying “Multisport unavalable Performance mode active”. Luckily I had my Suunto T6C mounted on the bike so I got my bike split, and just stopped and started the TGT at the end of the bike to get it going on the run, but lesson learned: Check the mode is Multisport right before the swim start!

    PS – Going for 3 entries into the TGT Giveaway!


  63. Congratulations on a truly great review. Your detail and testing was great. As a way out of shape viewer and dreamer of triathlons, this is a tool that I would love to add to the toolbox as I continue getting in shape. Thanks again!

    Great review thanks. Now im really stuck in which one to buy.
    timex or the 310xt??

    My deciding factor is: I taining in an indoor pool all winter long and I want to track my distance. Which device will work best? It sounds like the 310xt, but would like you opinion.

    Thanks for your in-depth review. I’m also an owner of a Forerunner 405 and wanted something for multi-sports. The Timex fit the bill. My only concern was the GPS acquisition..

    I received my Global Trainer yesterday and re-installed the latest firmware although it appeared my watch already had it done from the assembly plant (current crop of TGT’s).

    The purpose of this comment is to say that my watch locked into the GPS signal pretty fast. I timed it and it took approximately 36 seconds to lock in and be ready to go. I know it will vary from location to location but as far as I’m concerned, it’s just as fast if not faster than my 405. Good job Timex!

  68. Hi Ray,

    Great write up – and I’ve finally gotten a TGT thanks to your review of the product. (Additionally, I picked up the same Garmin HRM and GSC-10 too…)

    So, today was the first ride with it, and the cadence seemed to work perfectly fine. The speed, however, didn’t, as it was consistently 3-5 mph slower than my bike computer (which is accurate according to the more recent bike split times from my half and IM races…)

    I turned off the speed/cadence about half way through a 1.5hr ride, and when measuring the speed/distance just via GPS, the GPS functionality of the TGT seemed to be quite a bit more accurate (when compared to my bike computer), but not 100%, although I’ll chalk that up to simply both of them not being perfect.

    My question is this – you mention above that the speed/cadence has to be on SPC – what is that? I can’t remember what mine was set to when I started – possibly SCAN.

    Also, do I need to turn off the GPS functions while I use cadence? Seems strange if that was the case…

    Weird that it was so far off, but if you’ve broken a couple in the past, maybe I just need to get another GSC-10…

    Thanks for the input, and if you think it’s better to follow up with Timex directly, let me know – I assume you didn’t sign up to be tech support!

    Very cool and well documented review. Like it. Close to get one Timex.
    Although never satisfied to have all functions included, is there an ability to have waypoints marked while out in the world? Would like to mark interesting points and use the marks to create a new course lets say on a Garmin Mapsource software.

    You write excellent reviews, so happy I found you with google. I am now trying to decide between the TGT or the 310xt. I run some (although I have signed up for my first marathon next year)so I will be running more, like sprint tri’s and I love to bike. I would like basic information, not real in depth. I love to compete but at 55 I am not looking to take off seconds, finishing the best I can keeps me happy. I will probably hit the treadmill some this winter, does that mean I need to choose the 310xt?

  71. Hi Bernard-

    RE: Button layout/cleanliness

    When I talked with the folks at Interbike, they recongnized there’s a bit of work that can be done around the button interface with respect to the mutlisport mode. They’re looking at this for TGT2.

    RE: Indoor pool training

    For indoor pool training, neither will track distance – but both will work equally well from a simple timer standpoint.

    Hi Anon-

    RE: GPS accuracy

    In general, I find it’s been resolved, though I find it less accurate in trails than on open road.

    Hi Caleb-

    RE: Scan

    Scan means that it’s not paired, but rather looking for a Speed/Cadence (or other) device. In other words, it’s not gathering data from it.

    Hi Swisspeak

    RE: Mapsource Software

    The MapSource software isn’t compatible, but you can make waypoints via a track in the Timex software, not nearly as intuitive, but certainly functional.

    Hi Marsha-

    RE: Treadmill

    Yes, the TGT doesn’t support any footpod devices and I have word from Timex (engineering/development teams) that there are no plans to support foot pods with the current TGT. It’s likely the next version will support it. Thus…the 310XT is the way to go for footpod support for tri-focused peeps.

    I am looking at one of these watches to start running with, I have been in the gym since February and am just now in the shape to start running. I have two questions.

    1. I work out in the gym a lot and weight train. Will the hrm and calorie counter work well to turn on when I get in the gym and leave on the whole time for treadmill/elliptical and weight training to tell me how many calories and my avg. heart rate for both.

    2. What is the difference between the t5k267 and the t5k444?

    Hey Rainmaker great review:
    Can you make the font/text bigger?? when i use auto-split to get my mile intervals, the text is soo small it is barely readable w/o having to actually stop running to look at it. ON the Garmin text is three times a big and easily readable. Is this a problem for anyone else out there?
    Also is there a way to make the audible beep louder? Running outside on windy day could barely hear watch beep thus missing my mile markers. Again, On the Garmin the beeps are very loud and noticeable… Thanks scooter

    Overall very disappointing product. I have tested this product in dense areas (NY city central park) where most of triathletes train as well as in the columbia county areas (upstte NY). I have experienced major issues with tracking accuracy and GPS locking. It is just not happening. I would warn everyone to NOT buy this product. Very WEAK!

  76. Hi Tommy-

    RE: Calorie Counting

    I’d need to double-check, but if you’re wearing the HR strap it should do HR caloie counting.

    Hi Anon-

    RE: Changing font size

    Apart from lessoning the number of data fields, no.

    RE: Beep louder

    No, no way to do this (no other watches that I know of have this).

    Hi Anon-

    RE: Central Park Sat Reception

    Hmm, I used the device in Central Park without issue (in fact, many of the photos are from Central Park in this review), also used in NYC without issue.

    However, as I noted in the review, it’s critically important that you have the Sept firmware update – without it, the device will function like you noted with loss of satellite signal.

    Thanks for the review, there are mixed responses to this watch and I’m no more convinced by either this or the Garmin 310XT!

    I’m in the market for one of these GPS watches. I’m not sure if you can say or otherwise but if you were going to buy a GPS watch out of the Garmin 310XT or the Timex, what would you go for? There’s a lot I like about the Garmin but the Timex somehow feels like I could use it almost daily as a watch too, which is somewhat important for me.

  78. Warner

    Hi, I was wondering if anyone had a chance to test out this new firmware (v2.94) or whether anyone knows what changes (improvements?) were made.It’s frustrating that Timex won’t provide a Change Log! thx

  79. Anonymous

    Thanks for such an in depth review, very informative. I just bought the watch and i’m having trouble with the speed/cadence sensor. They paired an indicate so on the watch but the speed information is inaccurate. I can turn the pedals manually and only get up to maybe 20mph with the cadence meter up to 116. when pedaling it only averaged 12-13 mph. I have a Garmin 310xt and didn’t have this problem. Any suggestions? I have the Garmin speed/cadence sensors not the Timex. thanks, chris

  80. Warner

    v2.94 device firmware info (as per support):
    “Along with the regular update on your GPS satellite, your are now allowed to view your heart rate in percentage as well as BPM.”
    Holding the stop button now displays a count down timer before saving your workouts.
    There’s more for sure but this is all I got for a response…

  81. Larry

    Bought the watch a few months ago. Twice when I got in the water as soon as it lost the GPS signal the entire watch froze and was locked up for about an hour…returned watch. Any idea if this is a known issue that has perhaps been fixed by now?

  82. Brad

    I do alot of indoor training in the pool and on treadmill.

    Which software set (Garmin 310xt or Timex Global Trainer) would be best for manually entering distances to database via computer?



  83. Anonymous

    i think what tommy was asking above, and what i wanna know, is if the heart rate strap that comes with this watch is compatible with the heart rate sensors on gym cardio equipment (like polar’s is).

    this is the one reason i believe i must purchase a polar …i can’t lose that treadmill function!

  84. Can Timex share more Change Log information on the latest firmware (v2.94)? What are the updates?

    Rainmaker – do you know if this also improved the GPS accuracy?

    Thanks again.

  85. Your review convinced me I had to have this watch. Thanks for a great writeup.

    I have the 2.94 firmware and am getting wildly varying paces during my runs while my HR is pretty constant. So, for the same effort, the pace on the watch indicates a variance of over 70-seconds! I’ve got it set to the highest smoothing level (could that be the issue?). I may, yet, send this watch back since the pace function was the main reason to purchase. It also doesn’t allow for setting negative splits (could this be done via “intervals”?). It’d be great to enter a finish time and negatives percentage (say 5 or 10%) and have the pacer function (although useless due to wild fluctuations) pace the negatives.

    Again, thanks for the great review, but I’m getting ready to box it up and send it back.

  86. Hi Warner and others:

    RE: v2.94 change log

    I’ve e-mailed my contacts in the Timex Global Trainer engineering team, as well as the Training Peaks folks to see if they can put together a public release log for v2.94 – I’ll let ya know as soon as I hear back.

    Hi Anon/Chris-

    Hi Brad-

    RE: Indoor training

    If you’re using a treadmill, then the FR310XT is your only bet. As far as manually doing it on software later, it’s a wash – but TP and GC will do this relatively easily. Sports Tracks will do it better though.

    Hi SonOfLibery-

    RE: Firmware

    I’m trying to get clarity on what’s changed here, to see why you’re seeing the isues you’re seeing.

  87. It’s too bad Timex can’t just create a support forum so you’re not stuck in the middle offering help!

    I found an interesting anomaly in the 2.94 release. The GPS provides pace, and therefore, distance when there is none. I went nowhere, but went over half a mile during my bike workout.

    I wonder why the software assumes movement when the LAT/LON don’t change? You can recreate this by simply sitting on your couch. Start the chrono and watch the miles pile on at a snail’s pace (variance from 71-min/mi to 93-min/mi) all without moving a muscle.

    Anyhow, I think I found the problem with my pace smoothing not working very well (part of it is what happens above). I may have inadvertently hit the erase button in Device Manager (I have to assume that erases the configuration and not the workouts(why that isn’t under the settings screen I’ll never know)).

    I reset the config and will give it another run once it stops snowing.

    Thanks for helping out!

  88. Nate

    Thanks for a great review. As a result i’ve purchased the GPS watch.

    Since it appears you ended up being stuck in the middle of Timex support and us users could you ask them the following:

    Would it be possible to add a few very very simple features to the Navigation functions so that the watch would be a useful tool for Sailboat racing. For example, would it be possible to project a waypoint using compass bearing and distance. In other words, from my current location, create a waypoint that is X degrees and X distance away from me.

    Also, a sailboat racing countdown timer with standard countdown alerts would be great.

    This should all be very simple to do since they are just fine tuning of key features already offered by the watch. I’d be happy to provide some detailed feedback if desired.


  89. I’ve had my global trainer for a few months now and still can’t figure out how to display the pace or average pace for the lap or split I’m currently in. I know that when I hit the split button I get a quick review of the lap I just left.

    Surely it must be possible to have a realtime display of the lap or split that you’re currently running in? If not this is a huge oversight and to my mind makes the global trainer barely a step above useless. Help!

  90. Hey Ray,

    The other day, I was doing a long run, and I went out at a pace faster than I anticipated. As such, I needed a rest halfway through. So I decided to walk a bit. I couldn’t figure out how to pause the timer though – it just recorded it as a new lap. Any ideas?

    This is actually an item I brought to the development team as I want it as well. I’ve been told it’s something they’re looking at.”

    Any news about that issue? Is it maybe already contained in the last firmare 2.94 (I haven’t install it sofar) ?

    Thanks for your help,

    Hi Ray,

    Still enjoying your Blog, thanks!

    I have an update on racing with the TGT. In a recent Ironman race (IM Western Australia), I decided to use the Timex GT against my better instincts. I had been having problems with the TGT when cycling as it regularly drops the signal between the speed/cadence pod, and doesn’t automatically go to satellite for speed when this happens (which I would have thought logioal.

    I thought I wouldn’t worry about this too much when I got a Garmin Edge 500 (which locks onto the Timex speed Cadence ant+ sensor with amazing tenacity). So, for the Ironman, I thought the TGT would be a good watch for the overall race with the Edge 500 as a back-up (but as my primary visual monitor) on the bike. Everything was going to plan until about 3 km into the run, when the TGT stopped displaying pace – despite showing that it was locked onto the satellite signal. I planned my marathon on a specific pace per km and although I was able to switch to a customiseable screen that had event time and segment time, I didn’t need a gps computer to then do the math in my head to work out my pace! Needless to say after the race, I have no data for speed/pace elevation etc. Nothing except Heart Rate.

    I have to admit I was seriously considering switching to the Garmin 310XT after that. I noticed many people wearing them at IMWA and anyone I asked later said they have had ZERO problems with them.

    This was before installing the latest firrmware and I’m going to give the new firmware a go before making the final decision. But TIMEX has lost my advocacy.

    Just updated my Timex Global Trainer firmware from version 2.84 to 2.94.

    Can we find out what’s been fixed and/or added in the firmware versions. In particular v2.94 and future versions? If so, where please?

  94. it looks like the device agent is only available for the newest version of mac operating systems (snow leopard). Do they seriously not have a version for older mac computers?

    I was actually looking at the Garmin 210 recently but have found this watch cheaper and of course it has much more functionality. At around $175 at some vendors, I am giving it serious thought as a watch that I can grow into. Does the technology change so fast that this thinking is flawed? Any thoughts?

  97. This comment has been removed by the author.

  98. Timers…Do they actually work on this watch? I received this watch as a present a few days ago, and updated to 2.94. I’m trying to get countdown timers to work in performance mode, and so far have had zero luck. I’m trying to set up multiple timers,”food” and “drink” Someone earlier suggested making each timer a separate screen, and that worked to activate a single timer, but not both. Any help would be greatly appreciated!

    I’ve contacted Timex, but no response (holidays here in the States, hoping for a response this week). Does anyone have a copy of 2.84 firmware? Maybe it’s a software bug?

  99. Well I think I answered my own question. The manual states, “Timers
    There are five custom timers you can view in the performance data fields.”

    When I read this, I took it to mean that you could use up to 5 timers simultaneously. Maybe I’m just spoiled by the Timex Ironman 150 tap-watch which does food and drink timers simultaneously w/o problem, or maybe it’s the programmer in me, but running more than 1 timer at a time seems like a gimme feature.

    Please tell me I’m missing something, or getting very frustrated over something I’m misinterpreting. When using Device Agent to configure my Displays, I’m told I can only have 1 timer per display. Fine. I’ll set up 2 Displays, each with 1 timer (Food and Drink, for example). But if I don’t start the chrono from the screen that has the timer assigned to that specific screen, the chrono starts, but the timer(s) on other displays do not.

    I have been using this GPS watch for about a month and alas, it is going back. I love so many of the features and feel it is very usable and it gives me ALL the data I need as I semi-serious runner. BUT, the thing is so HUGE…I mean really huge. It is like wearing a cell phone on my wrist. I didn’t worry about the size or look of it until I started having hand and finger numbness when wearing it on long runs. If I wear it over an hour, I get a parasthesia. I canover look no foot pod. I can’t overlook nerve damage.

    The firmware version 2.94 is now displaying cadence from the Powertap.

    There seems to be a discrepancy in your review about the lap averages though, which states that all the averages are based on the current lap. I tested this and the value for Power – AVG is always for the entire workout, I can’t find a way to get the lap average.

    I really want to like this device however it appears that the engineering team failed to research current other product features(Garmin) before releasing this. The missing vibrate feature is a huge mistake IMO. The excuse to keep the cost down is lame. They should strive to produce a superior product, without that market share will continue to go to the category leader and we all know who that is.

    Well, I decided to pull the trigger on purchasing this despite the mixed reviews out there. The price was exceptional. I need to say straight off that I am not a tri-athlete, I am a runner. Once uploading the new firmware and setting the watch up to how I wanted it via the software, I headed out for my morning run. The watch locked onto satellite in less than 30 seconds and stayed accurate for the duration. I have three fields set and the info was clear and easy to read. I am pleased and after saving over $100 from a Garmin 210 hope that I will continue to be pleased moving forward. As for the comment about a cellphone on the wrist, the watch could not be much lighter given the size of its face and I think for most people that will be a non-issue.

    Run my first marathon and used global trainer. The route includes two tunnel 800m long. When I finished, distance measured is 1.6k short of 42.2 but running buddies’ garmin got about 42.2. Reason is satellite signal is lost in tunnel but when it is reacquired it should at least include the straight distance from last acquired position(before going in the tunnel) to the next satellite reconnection (coming out of tunnel). at least it is an approximation since the tunnel maybe not be straight.
    hope timex can fixed this in their next firmware update

  104. Just got back into town from Orlando, where I used my Global Trainer in a race for the first time. I say race, but it was more of an organized event. It was the Goofy Challenge. It handled wonderfully! As I posted before, I was nervous to use it, because I’ve been using the Timex Ironman Tap watch for a while, and have become relient on it’s timers for food and water. While I still think the timers are misrepresented and improperly implemented on this watch, everything else worked great.

    I charged the watch before I got on the plane, used it for 6 hours, and when I plugged it back in at home, I was at 60% battery life left. That’s with GPS on. I reset the GPS when I hit Orlando, and in the morning I found signal in under a minute. Mile marks were right on, and I used hands-free splits. Weight was not an issue. I actually noticed my roadID more. Screen visibility was great in light and dark (race started at 5:30AM, lineup was at 4AM). I’m happy to go into more detail about it’s performance at request.

  105. hmmm, first trouble using the watch.
    I did a multisport training tonite.
    30 minutes on the stationnary bike, 20 minutes on the C2 rowing machine and back for 30 minutes on the bike.
    As a former rower, I know how to row.
    Uploading with the device agent and on trainingpeaks, I lost all the rowing data.

    I used the multisport, and everything went fine while i was training, but the rowing datas are just lost, somewhere in the cyber espace. When i recall them on the watch, the 2nd lap doesnt show any HR datas and on training peaks, after a while, there is a blank between 00:29:29 and 00:40:16 when the missing datas are about 20 minutes…
    Kind of weirdos.
    Did it happen to anyone?

  107. Why can’t Timex be consistent on the watch bands for the Ironman line of watches. I would really prefer the velcro band as used on some of the other Ironman models. What happens when you need to replace the band on the Global Trainer?

  108. The “warning” and “without hands” beeps i cannot hear while running (low volume), which results in looking all the time on my watch. Do you also have that experience and can this be improved. Beeps from 310XT i can hear clearly.

  110. I received this unit this week and will be testing it this weekend while sailing. (the main reason i bought it was the nautical units)

    I too am looking for a better start time (count down timer) with alerts sounding at 5, 4, 1, 0.

    The navigation point of view. I have the same request as Nate. giving us a Bearing to a mark and distance would be awesome.

    Thanks. this report really help me decided on this unit.

  111. I received the watch as a gift. I am happy with, although it took some searching to find out that to activate a customized timer you need to bring the timer up in one of the fields in a customized layout view, and have this layout view on the screen when you press start. But the Garmin Connect software, which is free and WORKS GREAT, make the Garmin the hands down winner. (Timex records 7.1 mile workout, TP shows it as a 6.7 mile workout. Very bad.)

    How will this watch do under trail running / mountain biking conditions, will thick covering forests be an issue with GPS reception? Also, could this be used for canoeing and rock climbing?

  113. I use my Timex Global Trainer almost exclusively for trail running and have only a few hiccups. I find that if I set it on the car when I first start it up while I put on my shoes, I don’t have any issues with losing signal. It does read a little short on distance compared to my wife’s 310xt, but this seems to be by design. I used the Global Trainer this past weekend for the Uwharrie Mountain Run and it was only short by about .3 miles (8.1 vs 8.4) and I had no issues with dropouts. The Garmin 305 is known to lose signal in Uwharrie National Forest, so I was pleasantly surprised.

  114. Ray,

    I noticed back in a September 9 post that you were recommending the 310xt over Timerx Global Trainer. I am particularly concerned about the comments I’ve seen regarding difficulty in obtaining and keeping a signal, battery life issues, and distance measurement errors. Has Timex fixed any of these problems and do you still recommend the 310 xt over the Timex?

  115. Great review. You really dig into the workings of this system. I saw that you recommend the 310xt over the global trainer, but does your recommendation change any with the global trainer available for ~$200 and the cheapest 310xt at $350?

    Hi there,

    Thanks for your reviews on the TGT and 305.

    I’m new to running but do a lot of challenge walks over here in UK and am kind of thinking of getting a GPS watch for running and walking side. I have a question about what I should go for and since you come across as highly knowledgable in both the sport side and the kit side I reckon you will know.
    I am considering a watch mainly for the running side of things and to record trails whether run or walked. I am a self confessed geek about things so I know I will get into it. I already have a basic GPS for walking which I don’t used for anything but grid references (in UK we have the GB OS types of grid reference, not sure if you are familiar). I understand tht only the 310XT and the TGT offer this. Am I correct? Whilst I’d like this function so I can leave my old GPS60 behind I reckon since I never take it I really shouldn’t be too bothered about the location reference read out function.

    Basically in your opinion if I really just want a watch to record details about a run / speed walk with HRM is it really worth getting the TGT or 310XT or better to save and get the £100 305? I am never going to be a triathlete and only run to improve my fitness for walking and challenge walks so does the TGT or 310XT really offer any advantages over the 305 for a general plodder?

  117. So never saw this answered… When using the speed cadence sensor a previous comment said you had to disable the gps to use it. Is this correct, if so seem very strange.
    Have a suunto t6c and have been having major durability issues and dont want to spend more money to get the speed cadence and gps add ons for it.
    I could buy the tgt for the same price as the two add-ons would cost me for the suunto.
    Also looking at the garmin 310 xt but really like the price of the tgt.
    thanks for your reviews!

    RE: Comparison with FR210

    They’re very different watches. The TGT is aimed a multisport, whereas the FR210 is aimed at runners. If your goal is primarily GPS tracking at a basic level, then the FR210 is the way to go, else, the TGT.

    Hi Pierre-

    Hi Mike/Jace-

    RE: TGT vs 310XT recommendations

    The 310XT costs more, and there’s more than one reason for that. Some is componentry, some is features, and also simply because it’s a more established product. See my full recommendations page for details on which ones I prefer:

    My general recommendation around pricing doesn’t change too much – the TGT is heavily discounted these days – putting it closer in line with the FR305 from a price and functionality standpoint.

    Based on your requirements, I’d recommend the FR305. You’re likely to only use that featureset and not need the additional battery life or waterproofing (deep) that the TGT offers.

    Hi Matt-

    RE: Using speed/cadence sensor disable GPS

    This was initially an issue – but it was corrected in the July timeframe in the Training Peaks Device Agent (the issue was actually there, not in the watch).

    Thanks all!

  119. Is the timex version of Training Peaks different from the regular basic Training Peaks? The reason for asking is that the screen shots in the review show Timex Training Peaks and don’t necessarily look like the screen shots I have on my regular TP account. BTW, I had a basic TP account before getting my Ironman GPS. I noticed the possible difference when I was trying to download a run over the weekend to Google maps. Thanks for your help.

    Hi Rainmaker,
    I read all you rblog and found it very interesting, I’d like to buy Timex GPS… but not so sure now.Have you heard or now about udates to the faults you found?

    another awesome and well-detailed review…thanks a bunch!

  122. Sarah

    Hi, I have the opportunity to buy the Timex off someone who won it at an Expo but already has a Garmin. I’ve never owned a GPS-watch – I’ve just used my Polar HRM and MapMyRun. 🙂 So, some newbie questions:

    1) I love my Polar because I can swim with it. With the Timex, to be clear, you can wear it on your wrist and wear the strap and have it track HR and time? Those are more important to me than distance, since I swim marked OW courses for training.

    2) Training Peaks – I have a free account now. A number of reviews on Amazon complain about needing the premium account to see any real data from the Timex, and it looks that way from your post. Your thoughts? (or anyone else’s who has it?)

    3) I’ve seen mention of a new version coming out this spring – any word on when that might be (i.e., should I wait for that?)?

    Thanks for taking the time to write such in-depth reviews. It is really helpful!!

  123. Sarah

    Gah – one more question, sorry!

    ANT – uhmmm…how do I know if my current bike computer is ANT?

    Split/lap distance in a workout

    Finally good news from the Timex designers:

    “It will be added to the new firmware update for April”

    !! 🙂

  125. I have a Garmin 405CX also and while it cannot be used in the water it is a standard for feature comparison for bike and run. What I cannot do with the Timex and can with the Garmin which is basic:

    1. Display my split pace. i.e if my split is 1 mile I can’t display my pace in that split so far. The Timex only gives you your pace when you get to the end of a split. With the Garmin I can display in one of the fields my split pace. A great feature.

    2. Stop a workout without resetting. After I press stop on my Timex it will continue to “count” or “track” (whatever you want to call it) unless I reset. Obviously I should have to reset to start another workout but if I am done for the day and forget I end up with a 30 mile drive home. That’s just a pain.

    There is much more I am fighting with but maybe it’s there and I haven’t figured it out yet. Timex needs to stop being so pround and just copy what is right about Garmin. As it stands I am about to give this thing away and buy the 310xt.

  126. The Timex Global was my first GPS watch. I had trouble connecting it. Altitude was off. Speed was way off, and it is a beast. I exchanged it for the Garmin 110, saved $100, and love the 110 / 210. This 110 is everything the Timex wasn’t – everything so well thought out and supported.

  127. Thanks for the thorough review. I own the Global Trainer and I like it.

    Quick question: How do you calibrate the watch to the the Garmin GSC 10? On the bike, my speed/distance is accurate using the GPS, but I can’t get cadence. So, I got the GSC 10 and the cadence is showing great, but the speed/distance is way off.

    Please advise. Thanks a lot!

  128. Dave:

    Glad you got the cadence working. You have to configure the wheel size in the watch.

    Go to the configure menu and scroll to Bike. Then it’s a matter of updating the wheel size setting at the bottom.

    Hope this helps.

  129. hey there,

    would anyone happen to know if there’s gonna be further Firmware Updates for the TGT?

    Somehow for me, acquiring a GPS signal is always a pain, while my fellow running mate has no such issues using the Garmin 305. I wonder if the implementation on GPS will be improved with a Firmware update?


  130. Ouch, catching the GPS signal is sometimes odd.
    I always do the same routine, before starting my training: walking back from the office, getting upstairs to my flat, then back on the street to start.
    Usually, i’ll get the signal a minute after i turned on the watch, walking that giant place. Yesterday, I didnt catch it until I stopped 5 minutes into my training, in order to stretch a wee bit (and catch the signal).

    My problem for a couple of weeks: I no longer get the bike speed from the speed and cadence sensor. It worked fine for two monthes. I still get the cadence all-right and the gps works fine (I got the track on the map afterward).
    I reset the firmware, I reset the sensor, still it wont give me my speed on the bike.
    Speed/pace work fine for other activities.

    Hi everyone

    I wonder if you could advise me?

    I’m looking for a gps watch mainly for running and cycling.

    Have looked at timex/garmin/suunto.

    I want a watch that displays current speed and distance.


  132. I ordered on the advice of my brother’s a Timex Global Trainer at Amazon. I have already tested a 800cx Polar and Suunto T6d.
    Unfortunately, the Timex came without instructions in German. Otherwise, I could intuitively. Very annoying is that I can not export training records without a premium account. This will give the reason for me to be the clock back.
    I draw my data since years in other sports programs. I will continue to do so. Now this is doomed to failure.
    This post I use the Google translator (German / English) posted. I hope the review is understandable.

    Greetings M.F.

  133. Dear DC Rainmaker
    I just ordered the Ironman. I am going to use it mainly on my dingy, so in navigation mode a heading would be very useful. Do you think the Timex boys change the software in that way? Is it possible to charge the watch on your usb carcharger?

    Thanks for your great review.

    Best regards

  134. I haven’t been back here since last August when I posted, I returned my Timex GT b/c I never saw the firmware update and I couldn’t spend 5 minutes standing around waiting for a satellite lock to start my run. Do you know if the firmware update was ever released? Been using Garmin 210 ever since and its good, but I miss the split screens.

  135. Andy

    Firmware version 2.94 released 23 Nov 2010 is the latest version. It’s available along with the other downloads at link to timexironman.trainingpeaks.com

    Incredibly detailed review! Thanks so much. How do you get the time?
    My TGT arrived yesterday, 18 May. I’m hoping the device can handle multiple users so my wife and daughter can use it also.
    Thanks again for what is, actually, a great user guide. Hope the folks at Timex are watching.

    This is such a great resource. Thanks for putting all this time so everyone can benefit. Despite its short comings I went ahead and order the TGT, I hope it works well.

  138. Iv come across ur comment about the distance being short by 2.5%. How about for the altitude? My watch displays big difference in altitude for the same route. My watch would display a diff in high and low alti of 50m, at another time the diff would be 80m (for the same route). Is there something wrong with my watcn?

  139. Any feedback on altitude for timex global trainer? My watch is giving very diff results im altitude for the same route. It can give a diff in highest and lowest alt of lets say 50m, then at another time it woukd display a diff of 80m–for the same route… Should my watch need servicing? The distance is pretty accurate as far as I know…. Thanks…

    I need to send my Ironman back for repair. Basically the face has got badly scratched and 2 of the small bolts on the front bezel have snapped off.
    I have to say i am not impressed as i certainly dont recall continually hitting it against something.

    Can someone please tell me who i return it to for repair.


  142. help!?

    i have problems connecting my garmin cadence sensor to my timex global. tired to scan but can’t detect. am i missing something here?

    thks in advance


  143. Hi,

    I bought the Timex and I have enjoyed it.
    I’ve been using the GSC 10 on my road bike without any problems.
    I recently acquired a new GSC 10 for my triathlon bike.
    Even though the TGT allows you to select different bikes, I have to scan a pair the GSC every time I change bikes.
    Am I doing something wrong or is this how is works?

    Thank Luis

    Do you know when a new model of timex ironman will come?

  145. FWIW, I own and could never recommend the TGT. I’ve had a few Garmins in the past, will probably get the next gen of the 310XT when it comes out to replace this.

    It totally fails to work intuitively during a race, IMO. Its very easy to stop accidentally, hard to flip screens, etc. Somehow the Garmins just get this right far more often than the TGT does; it feels like using a PC after getting used to a Mac. And the fact that the free version of TP is so crippled, whereas the free Garmin Connect is so feature-rich, just makes it that much more painful.

    The worst example I can think of is that, when you start a run, it may not have acquired a complete satellite lock. If you don’t notice this you can look down a mile later and see it saying, “Hey, I can’t get a lock, did you want me to start timing anyway? [yes][no]”. You can tell that the software developers (and I’m a developer myself) thought that using the watch correctly would be a higher priority for me than, oh, running or racing. Bleah.

  146. Anonymous

    I bought the TGT last week based on your review that the 2.94 software update cured the GPS satellite acquisition issue. However, I have to wait about 8-10 minutes to acquire a signal. (Once I get it, it hasn’t yet dropped out). The software came updated to 2.94.

    So, is this a defective watch or is there another update I am missing that will acquire satellites within at least 90 seconds. I don’t like the 310xt form factor, but if that GPS is nearly “instant on”, then I will probably return the TGT. If you have to wait more than 90 seconds, the watch is useless for me.

  147. Anonymous

    Bike shop clarified the satellite acquisition issue. If the TGT is on your wrist, any movement will significantly delay signal acquisition. Once I took off the watch and set it down, it took 20 seconds to acquire satellites. Bike shop says Garmin has same issue – does it?

    I just got an email from Timex stating that any ANT+ footpod would work with this watch. From reading the article and comments this doesn’t seem possible.

    Has anyone got a footpod to work with the Timex?

  149. I just asked the question about the ant+ foot pod support to Timex canada too and wait for their response!

    Since all the post about that subject have been written last year,maybe the watch is now supporting foot pod.

  150. In a july issue for a triathlon magazine in France, it is said that footpod were recognize by the watch.

    I would suppose it would require an update thru the device agent, but I cant find it on the timex website.

    hello there, I went out for a run with my new timex global and the garmin 305, and there were some major differences…the garmin said I ran 7.21 miles at 8:21 and the other said I ran 6.97 at 8:37. I know there is no way to prove who is right, but I’ve been using the 305 a while, and it seems very accurate…i’m skeptical about the Timex…thoughts? I can’t be on my half IM, wondering if the Timex is accurate…that ain’t good!!

  152. I just got this answer from timex canada :

    Thank you for choosing Timex and for contacting us. Please note that the Global Trainer (T5K444) does support Foot Pod. The article was probably referring to the fact that we did not have our own foot pod but that will be launching in December of this year. In the meantime a Garmin foot pod with ANT+ will work.

    Folks-I am not sure how to pair Garmin footpod to TGT. Dose anybody try to pair Garmin footpod with ‘speed’ sensor section in TGT.


  154. I just got my global trainer. Surprised to see you cant do a “lap pace” or “lap distance” in the fields of view. My old garmin had this and it sure is nice to use when doing intervals. Any work around you have come up with for these fcts?

    new firmware TGT – footpod ok!!!!

  156. yano

    Usual question: does anybody know what’s new in the latest firmare v3.14 ??

  157. yano

    … but for the footpod compatibility?

  158. yano

    Here I am again …

    just downloaded the latest firmware v3.14 (F-XGH-2B-1107201__3.14.GHX)
    and successfully installed it.

    Nevertheless, the TGT watch displays “VERSION 3.13 F-XGH-2B-1107201″

    Anybody else with the same “version numbering” issue ?!

  159. 3.13 also for me. I couldnt find any details on the update though.

  160. Anonymous

    The actual v3.14 firmware is posted.

    Looks like the latest firmware update now fixed the foot pod issue for running indoors. This is getting me one step closer to making a decision between the Garmin 310xt and the Timex Global Trainer. Ray – the last piece of the puzzle I’d like to know more about is the calibration feature of the TGT (or lack thereof). How important is it to have and do all Powertaps require a calibration?

  162. Hello All: A quick note about firmware updates to the Timex Global Trainer to add footpod support and potential satellite accuracy issues. A new update was released on August 4th, 2011 to add footpod support and a slew of new data fields and features. Additionally, based on some very initial testing, I’m seeing accuracy rates much closer than before. More information here:

    link to dcrainmaker.com

    Thus, for questions covering firmware updates or satellite accurary, I skipped if they were covered by the above. Thanks!

    Hi Bruce-
    RE: Training Peaks differences

    Yes, there are some minor differences, essentialy it’s a cross between the basic version and the premium version.

    Hi sarah-
    RE: Swimming with it

    Yes, you can wear it on wrist in water, but it won’t record HR underwater (strap signals won’t go through water)

    RE: Training Peaks

    I wouldn’t agree with that, it’s better than the free account today.

    RE: New versions

    Things are quiet at the moment, but I know a new version is in the works – the timelines are unclear.

    RE: Whether or not ANT+
    On it there will be a small ANT+ logo

    Hi Yano-

    Yup, this was added in the August firmware

    Hi DWPix-
    RE: Display split pace – the new firmware does this

    RE: Stop a workout

    When you press stop it’ll stop recording, no need to reset. I did this today without issue.

    Hi Julia-

    Hi Anon-

    Hi Crispin-
    RE: Altitude

    Altitude is GPS based, so not quite as accurate as barometric altimeter

    Hi Dan-
    RE: Cadence sensor

    Ensure you’re triyng to pair to a SPD/CAD sensor and not just the cadence sensor. You’ll want to press the little light to start the pairing process.

    Hi Luis-
    RE: Rescan each time you change bikes

    Try this again with the latest firmware.

    Hi Olivier-
    RE: Newer model

    Unclear on exact timelines at this point, but I suspect we’ll hear something by Interbike.

    Hi Chris-
    RE: Power Calibration being omittied

    I still believe this is a significant issue for power meter users. Without the abiliy to calibration, ones power meter information isn’t really reliable – especially in differing conditions and over time. I’m still baffled at why this isn’t included.

    Thanks all, and sorry for the delay here – been a bit of a crazy few months with wedding and honeymoon, just getting a chance to catchup on all the past comments.

  163. Bernard Maughan


    Good to hear your thoughts/comments about the TGT with firmware ver 3.14. I can verify that the sat acquisition here in Singapore is faster (except initially) and it looks like they achieved that by requiring the TGT to lock onto fewer signals (4 now – previously I never got a lock unless it had 6, and the last 2 took forever).

    I haven’t tested it for distacne/speed accuracy yet but will let you know what I find.

    As for the new versions, this from their Timex Sports Facebook page in response to a question:

    Robert CAfrica:
    Hello Timex, any news on the rumoured new GPS watch slated to come this October? Thanks.
    July 29 at 7:30am · Like ·

    Timex Sports: Hi Robert, The new GPS Run Trainer will be shipping to select sports retailers in Mid October

  164. Bernard:

    So it sounds like a “running” GPS, not a Global Trainer replacement. No multisport by the way they named it.

    About that new 3.14 firmware …

    I’ve not been able to successfully import the settings I exported directly before the update. It updates some stuff, like GPS settings, etc., but it does nothing with the performance screens (the choices for what to show on each of the four segments of the four screens). Anyone else seeing this?

  165. Bernard Maughan

    Hi everyone,

    I had a bit of fun pretending to be DC Rainmaker for a day (well, 2 days) by testing the TGT with Firmware 3.14. Sorry for not living up to hsi standards though – I didn’t take a camera along!

    I ran with my Suunto T6c and ANT footpod (I gave up using the hockey puck GPS pod ages ago), my Garmin Edge 500, and the TGT. All were set to autopause at 0.5km/h but I forgot to check the resume speeds were the same (they weren’t).

    First test was the Satelite Acquisition speed. I set the Edge 500 & the TGT on the ground and turned them on at the same time. The TGT was about 25 seconds faster than the Edge, which took 1 minute 45 to acquire a lock.

    I then ran one of my usual 5km+ loops, with the TGT on one wrist, the T6c on the other and the Edge 500 in my hand. The results were amazingly close:

    Suunto T6c: 5.72 km
    Garmin Edge 500: 5.74 km
    Timex TGT: 5.84 km

    The Edge and the TGT had the same average speed and max speed (or pace – too slow to publish :-))

    Realising that the autopause feature would possibly skew the results, I ran the same loop today with just the Edge 500 and the TGT with the Autopause feature turned off on both, and the results were even closer.

    Edge 500: 5.86 km
    TGT: 5.889 km

    I haven’t adjusted my screens yet to play with the different features, but I did order a Garmin Ant+ footpod.

    Sonofliberty: I’m not sure whether the new watch will be a multisport watch or not, but I think from some info I saw a while ago and the new name, I guess you’re right – a new running, biking watch, but not a multisport watch.

    As for your importing your previous exported settings: Once you’ve exported the settings (to save your preferences as to screen layout, user info etc.) then downloaded the new firmware (which erases your settings) and then importing the saved file back to your TGT, you won’t see any differences. You have basically just reapplied your preferences and user data, timers etc.

    You should see the new display/recording options once you go through the Screen setup/field layout process.

    If not, start over by downloading the new Device Agent, and applying it, then download the new firmware, and then upgrade the watch as per the instructions from TrainingPeaks:

    “After saving the file to your computer, use Device Agent and select “File, Update Device” and follow the prompts to perform the firmware update. You must use DA build 3.0.57 or newer with this firmware”



  166. I use the TGT as my primary running/cycling ‘coach’ and always take my phone with Sports Tracker for comparison. The TGT is definitely acquiring GPS signals much faster. I have noticed the distance captured by both is pretty close.

    For one of my last training runs, Sports Tracker registered 13.6miles, TGT 13.58miles. The difference in duration was 2secs. I also use the elevation tool within Training Peaks to correct my route elevation and distance and thus far the the latter has been only 0.1/0.2miles out.

    I also like the new lap/split pop-up display – 5 seconds is not enough though. Maybe 10 seconds or an ability to set the display time would be nice.

    I also noticed that your weight is also transferred to the Training Peaks software.

    One workout for me are mile repeats with a quarter mile walk in-between.
    Does anyone know if the TGT can be set up ‘beep’ after the mile run and quarter mile walk?

  167. joetri

    Well, first of all, thanks for a great review. Superb and very detailed. I even have gone and read most of the other reviews even for items I will probably not purchase.

    I bought the TGT about a week ago after reading your review. Have to say I’m very pleased so far. I was using a Suunto t6d which has worked great for me for the past 10 months or so. I have it coupled to the Suunto bike pod which also worked great.

    Now I really like the GPS on the TGT. I did the firmware update the very first day I took it out of the box. Satellite acquisition is quite fast and distance accuracy seems to be fine with a deviation of around 50 meters after a 15 mile ride, compared to my Suunto which I know to be on and off sometimes too.

    I haven’t been able to use it extensively, but so far only one comment/suggestion. I wish one could set different alerts for distance/time for the various activities. For example, that I could have the watch do a split every 1 mile while running but every 5 miles for biking and so forth.

    Besides this, I’m highly satisfied with the product.

  168. Just posted a review of the TGT on Amazon – it’s getting panned there and I think unfairly based both on my experience using it for a year and based on this review.

    looks like a ton of Runner-only folks who weren’t too happy with early glitches. Given the recent addition of the footpod – which seems to work for me (not for distance though…but I haven’t calibrated it yet).

    Any thoughts on all the negativity at Amazon? Great Reviews RainMaker – I continue to read and click through to Amazon to support your work! Just wonder if folks are getting turned off by the less-than-scientific work over there…

  169. Quick question about the new updates. The recent addition of the footpod makes me wonder, why do I want it? What does it add over GPS? I used a Nike+ for a year or so before getting the TGT, wondering what it will add, does it work with GPS for more accuracy? What added measurements can I monitor with it?

  170. Hi Bernard-
    RE: New Timex Run Trainer

    Indeed, thier half-announcement of the product last week and page is definitely a run focused GPS watch that seems to go line-by-line against the Garmin FR210, from price to features. I plan to do a comparison this week from a feature standpoint. In the meantime:

    link to timex.com

    RE: GPS accuracy testing

    Cool results, and seem very very similiar, especially once autopause is off (which would definitely affect it because of the lag and pickup time. Huge thanks for sharing!

    Thanks for the info/thoughts!

    Hi Hollywood-
    RE: Reviews

    Up until last week, the general reasons to pan the watch have been indeed valid. The GPS accuracy was off consistantly at 2.5% (minimum), and I found it to be much worse in many situations (see sidebar for tests). However, the firmware update was also never promised, so many people just gave up since there was virtually no response from Timex on the issues. Communication is key, and in that area, they’ve been slim.

    That said, huge thanks on the Amazon support – I really appreciate it! And thanks for dropping a comment by as well!

    Hi Bobby-
    RE: Footpod

    The key for the footpod for most isn’t replacement of the GPS, but rather supplemental indoors on a treadmill (or tunnels), as well as for running cadence information (steps per minute). Accuracy wise it can improve instant-pace, but the Timex Global Trainer actually had a 5-7 second smoothing algorithm in there to help with that anyway.

    Thanks all!

  171. Bernard Maughan

    Ray and all,

    Since Firmware Ver 3.14 I’m happy to see my TGT’s improved accuracy in speed/distance when running, but when cycling it still drops the speed/cadence sensor and doesn’t switch to GPS mode when that happens. Is there a way to select that the watch defaults to GPS when it drops speed/cadence?

  172. Ant+ foot pods are now supported with the 8/3/11 firmware update.

  173. Anyone else noticing that the first time the split/lap window pops up it’s empty?

    I’ve got my TGT set to lap every mile. The first time it displays the time window it’s blank, but is okay after that for the rest of the splits.

  174. yano

    >Anyone else noticing that the first time the split/lap window pops up it’s empty?

    the same here … 🙁

  175. yano

    EDIT: I’m right now back from my today run and … the bug is simply gone! No clue what’s going on but the first lap has been indeed displayed now … (I’ve set as well 1km autosplit)

  176. I just loaded 3.14 and will be checking it later this coming week.

    One issue that I would like see changed is when the TGT battery goes dead, that it keeps its settings. I should not have to reconfigure them or re-import them each time after charging from a dead battery. Committing the settings to the TGT memory may reduce the capacity available to store logs slightly, but the additional space usage would be so small that it would not be enough to cause concern.

    Also after downloading the new Device Agent 3.0.58, saving to file causes error ‘Unknown unknown’ and displays that it did not save the files to disk. But after many attempts I navigated to the saved folder and found it did save the logs to file. So it is displaying an erroneous error that is misleading. I even put in my username and pw for Training Peaks and it still does the same when saving to file.

    Otherwise I love the TGT. Would like to see them turn fixes around a little quicker. Prior to 3.14 I was beginning to wonder if they were ever going to push out a new fixes and was questioning my purchase.

  177. So, now, with the latest firmware (3.14), the bike speed goes a little nuts during the ride. I’ll be cruising along at 20mph, then, all of a sudden, the speed drops to, say, 14 for a few seconds, then jumps back up. It does this about once every minute. I didn’t notice this happening prior to the update. Anyone that confirm this behavior. Clear sky with the occasional tall tree.

  178. yano

    Device Agent 3.0.58 and bike speed are working fine here …

  179. Anonymous

    I’ve been using the TGT for about a month now, and have the lastest firmware update. I continue to have a problem with the accuracy of both the pace and distance on the run, particularly when running in areas with some tree cover. I will see the pace jump around a lot, from 7 minute mile pace to 12 minute mile pace all of a sudden, and the distance is off too. Any suggestions or fixes? Do other devices like Garmin 310xt or 305 experience the same problem?

  180. does someone know if garmin footpods will work with the new firmware?

    greetings from germany

  181. Holger: Yes, Garmin footpads that support the ANT+ protocol do work with the TGT. I have the Garmin SDM4 pod and it works fine.

  182. Anonymous: I, too, can confirm that the speed and distance do some jumping around on the run (w/GPS and foot pod active) as well as my previously mentioned bike ride. So, I’m seeing it on both and it causes the distance to come up short.

  183. I’m at my wits end. Finally. After waiting and waiting and more waiting for Timex to finally release the latest firmware to include foot pod, they screwed up the GPS tracking to be almost unusable. While riding today I set a personal best max speed of 128mph. Yep. All the while maintaining a cadence of 101 and watching the speed jump from 21mph to 15 to 13 to 18 and back to 21 all within four refreshes. Nice. This was on a semi-wooded road that didn’t have this problem before the 3.14 firmware. Not sure what to do at this point since I can’t return it and sending it in for warranty wouldn’t resolve the problem either. Ideas are welcome.

    What about to roll-back the previous firmware and compare the results?

    Am having the same erratic speed readings on training peaks from the TGT. But they don’t seem to be happening on the watch when checking the metrics in review mode.

    Talked with TP and they are working on a fix. Should be cured with next site update

  186. Does anyone know if the Garmin ANT+ stick will work with the TGT watch?

    I have just bought Timex gps global trainer. I would like to have sailing countdown. Can Timex engineer to add that feature.

  188. Have you had a chance to review the new Timex GPS watch yet? The one that come out in Nov.? If not, any idea when you’ll get it? Thanks!!!

    Thank you for your reviews – they are fantastic! Just the type of product research that I was looking for. I would like to get your opinion as I am in the market for a heart rate monitor. I am an experienced male runner who is looking to improve my endurance. I currently run with my iphone, primarily for the “Runmeter” app that tracks time, distance, speed, splits, calories, elevation, etc. I occasionally listen to music as well when I run and get messages every half mile from “Runmeter” telling me my time, split, mileage, etc. I like the app because it is easy – I don’t have to go to Training Peaks on the laptop – all of the information is right there on my iphone. I have two small children that take up a lot of my time; thus, the only time I am on the laptop at home is to do bills – that’s it. So here’s my question:
    1. Am I missing out by using an iPhone app as opposed to a GPS watch? I figure there is basically a trade off here – between accuracy and convenience, since the GPS watches will require me to boot up the laptop and look at the results on-line.
    2. What if I stayed with my iPhone, is there a heart rate monitor watch without the GPS tracking that you would recommend? With this regards, I am looking for something that is functional (e.g., can setup heart rate zone targets), has a good sized screen that I can read on the run, and has a comfortable chest strap? It seems like the “Timex Personal Trainer” (5G971) and “Timex Zone Trainer Digital Heart Rate Monitor” were rate high by Consumer Reports; however, the report looks outdated.

    DC… quick question. If you could purchase the Timex Globaltrainer for $200+/- w/ HRM (or even $165 at Schwaggle) or the Garmin 305 for $145…. what would you recommend for a new triathlete?

  191. Thanks for your review I’m using the TGT 10 months, what I want to share with other readers is the place I found on my TT bike. I was able to mount the handlebar holder on the end of my TT handlebar just before the shifters. the holder s hold on iits place with à 4mm tyrap, if you want I can send you pictures.


  192. The guy I am married to just snagged one of these (minus the heart rate monitor and bike mount) for 83 cents at REI. Eighty-three cents. I hope he gets his money’s worth.

  193. Thanks for the in depth review. I just ordered one via your link to replace my Garmin 310xt, which I left on my roof as I drove off yesterday.

    I am not impressed with Garmin’s quality. The Forerunner I lost yesterday was a $99 refurb that replaced one that failed out of warranty. I have two 305s that also failed out of warranty; one of those had also been replaced under warranty..

    I’m glad there is an alternative.

    Hi Ray,

    I got one question: Do you have experience whether it is possible/advisable to use two devices of two different manufacturers?
    I use for example the Garmin Edge 500 and would like to know if it is advisable to buy a Timex running device since there will be training sessions and competitions where both devices will be used.
    Would there be a software that can combine the data into one data base?

    Thanks for your time.

  195. Hi,

    I have a problem with the Alert based on the heart rate. Below is the Custom Heart Rate Zones I inputted in the system/watch:

    1 – 50-70
    2 – 137-152
    3 – 152 – 165
    4 – 166 – 175
    5 – 175 – 184

    How do i setup the alert that the timer i chose will alert on the heart rate zone indicated. Below is the interval timer setup.

    1 – 00:01:00 Zone 3
    2 – 00:01:00 Zone 1
    3 – 00:01:00 Zone 3
    4 – 00:01:00 Zone 1

    I did a test sitting down with my HR around 84-95 range. The Heart Rate Alert is On and Target Zone is Zone 1. This is the result:

    1 – 00:01:00 Zone 3 90-94bpm “Low Heart Rate”
    2 – 00:01:00 Zone 1 84-87bpm “Low Heart Rate”
    3 – 00:01:00 Zone 3 84-85bpm “Low Heart Rate”
    4 – 00:01:00 Zone 1 85-89bpm “Low Heart Rate”

    I did another test sitting down with my HR around the same 85-95 range. The Heart Rate Alert is On and Target Zone is set at custom 50 – 80bpm. This is the result:

    1 – 00:01:00 Zone 3 84-91bpm “Low Heart Rate”
    2 – 00:01:00 Zone 1 86-89bpm “Low Heart Rate”
    3 – 00:01:00 Zone 3 86-89bpm “Low Heart Rate”
    4 – 00:01:00 Zone 1 85-89bpm “Low Heart Rate”

    What could be wrong? Please help as I am now in training and Heart Rate Alert is very important.



  196. Has anyone figured out if you can deactivate the auto-shut off feature for the GPS due to inactivity? If you don’t start a workout within a certain period of time, the GPS will shut off. Not good when this happens right before the gun goes off!

  197. Hey Rainmaker – I have read your Garmin 310XT and Timex GPS reviews for the first time – AMAZING (where have I been??). OK, so I have gone through 3 Garmin 310XT’s all have died after about 12-14 months of use (water gets in, the screen goes foggy, then it dies). Just to clarify – I am a surf ski paddler and use the navigation function a lot and LOVE it. However, it appears that the waterproofing is not as robust as it should be. Just to clarify again, while I am on the water, the GPS is on top of the water and gets splashed but not submerged.
    So, sadly I am not a great fan of the 310XT.
    I am now considering a Timex – and am assuming they have their watch waterproofed.
    Here’s hoping!

  198. DCRM – Thanks for the in-Depth reviews — I too have been testing mostly Garmin Products over the last few years of my running / cycling / triathlon habits. I just recently unloaded my 310XT due to HRM inaccuracy after washing the strap (as you know on long runs and in heat those things get pretty nasty)..Garmin replaced one prior to the 1 year mark, but it seems as though it is having issues again tracking accurate HRM data…Saying my HR is in the 220-240 range on a zone 2-3 10k run…Which my avg is in the 170’s.

    Anyhow…Just picked up the TGT off that nationwide Schwaggle deal where it was only $165 w/ HRM (Excellent price) but am disappointed with its ease of use compared to the Garmin 301xt. It’s lack of use with other fitness equipment in the gym (namely Treadmills) is a huge detractor from its overall fitness applicability for us non traditional athletes who every once and a while venture into those recycled air germ nightmares to workout.

    After using it a few times it is working well (and its still under warranty) but it seems based on your new review of the 910xt I should be buying one of these — especially with as much lap swimming as I do ..Typically 4000-6500m per week. I appreciate all your wotk on these and please pass along any huge sales or discounts you may here of for the 910xt — with it being new the $499 price is too hard to swallow when I am still breaking in the TGT. Maybe I’ll sell it, if I can get that 910 for a good price…

    Looking forward to your next review…Oh and by the way — if you want any help Heat testing stuff I am here in Sunny and Hot AZ at your request to assist.

    Cheers !

  199. I am frustrated by this watch- buy the forerunner! It keeps freezing with my speed cadence sensor – so timex told me to get a new sensor – I now have 2- still freezes – so I changed the batteries on the sensors – still freezes. So I got a new warranty watch. Still freezes. I spoke with timex and it has been 2 months and they have not replied other than that their tech team is working on it. I have a 300 watch that I cant use on my bike… very frustrating indeed. Also GPS signal probems obtaining signal. If I don’t leave the watch outside, I don’t get a signal. Last week I ran 15km and it never got a signal (running by the ocean- so good view of the sky)

    • Patricio Rodriguez

      The new firmware version solve this problem. So far, so good. But have to buy a garmin for the meantime.

  200. Thanks much for the review and feedback from the readers. Amazon had a sale on today for the Timex with HR for $99. With all the info you provided as backup that was a price I couldn’t pass up. If nothing else it will tide me over until I’m ready to fork out the $$$ for the new Garmin 910XT – and that may be awhile.

    Awesome job. Thank you for taking the time for the review. I’m goona get one!

  202. Hi DC Rainmaker,

    I just received a Timex Global Trainer for Christmas. It is a great watch, except that now my various computers (Win 7 32 and 64 bit) will not recognize the USB device. I’ve tried uninstalling and reinstalling the software, to no avail. Do you have contacts at Timex, or maybe the USB driver to install manually?
    Thanks, and I really enjoyed the review!

  203. I am from Manila, Philippines and I would like to thank you for an in-depth review of the product. Your site has done our triathlon community here a lot of good and we wish you more power this coming year.

    I am about to take delivery of my TGT. My fr305 conked out on me during our one and only 70.3 here. This is going to be my replacement for such a great gps training and race watch. My apprehension mainly is stemmed on the inaccuracy of the distance data. This would greatly affect the average speed as well and this might be a source of regrets in the end. I hope it lives up to my expectations.

    Warm regards.

  204. thelastlaugh

    Thank you for the review; I love this watch and purchased it based on it, but I’ve started to have problems now that the weather has turned cold and haven’t been able to find any answers. I was hoping to use it in the winter for tracking my vertical feet while snowboarding, but the watch keeps locking up and factory resetting – losing all the settings and any workouts. Has anyone else experienced this and if so, have you solved it (and how?)

    During the other (3) seasons, the watch has been great. I use it for mountain biking mainly, but have also started to do more outdoor running. And to make it even better, they finally added foot pod support.

  205. desiree

    Hi, I just got my watch and it is not reading the correct time or date to even start. Is this because I am in doors and the GPS signal is weak. I am wondering how I get the right time and date so I can begin using it.



  206. Anonymous

    Use the device agent. There is an option to sync the time with the PC.

  207. Aug 2011 firmware update adds some nice features to the already great watch. Foot pod sensor and enlarging screen so you can actually read your lap/splits is great. Curious if D/C Rainmaker will do an update to review the changes they made finally with the latest firmware updates? Pat

    On my suggestion as an IT pro, the good people at Timex sent me a replacement USB cable and I am able once again to upload my runs.

    Anyone tried using the tgt for run walk method? If I want to run for 6min and 1min walk, how do I use the timers? Can anyone help?


  210. Nice review but I seem to be encountering the same problem as AdamZ where the TGT running firmware 3.14 simply freezes mid ride with portion of the screen blanked out where the alert would normally go. I also believe its related to the cadence alerts, anyone else has this problem or more details on a resolution from TIMEX?

    I used this watch as my first, during my training last season for my first Ironman, and have been very satisfied. The one thing people keep making remarks on is the ONLY 15 hours of battery life – well if you can’t make your iron distance in less than 15 hours you will off cause have a problem…….., however that is one more reason to train hard. Anyway I am now considering the Garmin Forerunner 910XT because of the extra Swim features, the improved design, and the vibrator alert, unless Timex plus out a surprise Very fast.

  212. hi…can you teach me how to download the google map into jpeg format? thanks

    For some reason I can’t get my Garmin speed/ cadence sensor to read. My watch skips over the Speed/cadence sensor in the menu, only giving me the choice to scan for speed or cadence. So, I select the cadence sensor, press and hold the reset button per garmin, hit scan on watch, pedal bike, and the watch never picks up the sensor.

    Any tips?

  214. I got this watch about 2 weeks ago for around $95 on Amazon (It was a “like new” unit) When I got the package the USB charger/cable was not included. Thankfully, I was able to order one from Timex for $10 and it arrived the next day.Kudos to Timex’s customer service as they were very good. (Amazon gave me a credit for the cost of the cable + shipping for my troubles)

    I have used it on a number of runs and it has performed pretty well. I got the newest software update. I have no trouble acquiring satellite and it usually takes under 30 seconds.

    I have also used the Garmin footpod on a number of runs to measure cadence & I used it for distance on the treadmill last night with no problems. I’m glad this feature was added.

    I’m still getting used to the size of the watch. The distance measure does seem to be off, but I notice it’s getting better with the more runs I do. Certainly in the 2-3% range. I do like the buttons and the software. I

    It does have a few quirks, but considering the 305 is now getting pricey again. I think this is a more viable option out there especially for the price now.

  215. fwiw, the Timex GPS Global Trainer i picked up in February 2012 has firmware that supports ‘constant-on INDIGLO’. here’s how:

    if you press INDIGLO button for 8 seconds, it stays on all the time

    if you press for 4 seconds, it activates ‘Night Mode’ which turns on INDIGLO with any button press (not just the INDIGLO button)

    any other time, it only comes for about 4 seconds when you press and release INDIGLO.

    very good review! and Iam very happy with my Time Ironman GPS Global Trainer, but recently I was worried because the display begin to fade.It lightened compared to the first time I use it!

    I have recently bought thr BTWIN cadence/speed sensor from Decathlon but cannot get this to work with my Timex Global Trainer any suggestions ?


  220. dear DCRainmaker,

    thanks alot for such a detailed review on my favorite watch, the Timex Global Trainer. After reading through your review, immediately I purchased 2 units on this watch. It is too bad that Amazon does not provide a courrier service to my country, to my dismay I have to use another portal in order to get to my watch. eBay!
    I have been using Cateye V3 for the past 3 years. Now it is time to option for such upgrade, a much higher grade one + GPS tracking. Cannt wait to impress my peers with such a wonderful watch. One thing which I am not too sure about the cadence/speed sensor (as well as the heart rate stripe) frommy Cateye, is it compatible with Timex Global trainer? I read the online spec on this watch it says anything with ANT+ would be just fine and they shall communicate. Well if I refer back to my Cateye spec, there is no indication on ANT+ but it has something like 2.4GHz ISM Band. Do you think they will work?
    I know I can always try it out when the watch is here(ah such a long wait it takes about a month to get here) but it is really not working, I like to go ahead and buy the Timex cadence sensor right now.

    thanks so much for your time indeed.

    Hello Rainmaker, i am considering buying a quarq and this watch. I understand that this watch is not able to calibrate a powermeter. But is it possible to use a wahoo iphone for calibration then use the watch with corrected power values ?

  222. Rainmaker or anyone,
    I need some help, I am apparantly not smart enough to figure out how to calibrate my footpod. it registers cadence but not distance regardless if the GPS is on or off. Any help would be appreciated. Thanks

    I own a Timex Global trainer and recently purchased a Garmin
    500 Edge which comes with a GSC10 speed/cadence transmitter.

    Here’s my situation. Garmin picks the Timex HRM and the S/C sensor. Global Trainer picks the Timex HRM but won’t pick the Garmin S/C sensor.

    I see from your review that you managed to pair the GSC10 with the Timex. The people at Garmin have told me that though the GSC10 is an ANT+ device, they cannot GUARANTEE that it will pair with the Timex global Trainer.

    I love the Garmin Edge for training but for my triathlon races, I need the Timex since it works in the swimming bit.

    Garmin Customer Service suggested I buy a Garmin GPS watch. Before I go into another expensive expedition, I’d like to ask you and your followers if anyone has any suggestions.

    Some have told me to remove the battery, place it backwards and re-pair the GSC10 with my Timex. That would mean I can only get one of my receiver devices to record speed and cadence…and that bugs me.

    Any ideas?

    I have two Garmin GSC10 and they pair properly with my Timex Global Trainer and Timex HR. Read TGT pdf Manual page 25.

  226. Hi,

    I’m interested in purchasing a GPS device, having read through this review I have a few questions:

    1. Do you know if the battery issue has been fixed?
    2. Do you know if the GPS issue has been fixed?
    3. You talk about an inaccuracy of 2.5% has this been fixed or is it still inaccurate?
    4. If you had a choice between this and the Garmin 310XT (price excluded), which would you honestly go for?

    Thanks a lot for your help


  227. I was updating the firmware on my Timex Ironman GPS and we had a power cut. All I have now is an empty watch, it doesn’t even display anything when switched on 🙁 can anyone help???

    Used your review to make the choice for the TGT. Did the update, walked outside and wham full GPS. I love this thing. Paid 130 w/HB mon shipped. A no brainer. thanks for your diligence.

  229. The device just arrived. I decided to use the usb charger on my PC. I got a blinking battery for 2-3 minutes and then blank screen….

    Now the charger does nothing and I have a feeling that I would be returning it….

  230. yano


    I’ve got the TGT since July 2011 (actually my second one: my first one was stolen) and I’ve had to send it now to Timex because it’s no more waterproof: by swimming (even under the shower) water comes in !!

    I’m really disappointed and frustrated!!

    It was told me that “Water Resistant 50M watches can tolerate a static pressure equal to 50 m depth for 1 hour, but are actually not suitable for swimming” !!!!!

    Is Timex making fun of his customers or what ??!!

    Anybody else with the same issue ?


  231. Johann Ong

    hi All, it is me again returning after 2 months of using TGT. Guys be extraaaaaa….. careful with the heart rate sensor. Mine stopped working just after two months! TGT failed to pick up any signal. Tried with my FR610 also to no avail. I had to get another replacement from Garmin. Believe me this is one heck of an expensive replacement item!! Hearbreaking still I got to replace it. After read through the Garmin’s manual, saw an important user notice that is “Unsnap the module before cleaning the strap”!!! I guess this is the reason I fried the sensor:( So please everyone be careful with cleaning and cleansing the sensor this is an expensive replacement parts!!

  232. Just an update on my device. The local service center managed to somehow make it work (30 Euros) and now I will make good use of it while it lasts 😛

    In general the build quality is mediocre. The buttons are flimsy and provide crappy feedback, also their placement is akward. When I try to operate it with one hand, my index finger is trying to push right side buttons and my thumb tries not to push left side buttons while providing enough resistance to steady the watch….

    I believe basic buttons should be place on the front side in order to be operated by using the thumb, just like a mobile…

    With firmware version 3.14 gps took 15” for initial satellite lock but I had to walk outside my flat. After that it locked almost instantly anywhere I was.

    I cannot make sense of the hands free feature. I want to hit the start button, run, auto stop, hit start again and so on.

    So, I set auto start to OFF and auto stop when speed < 2 km/h. I press Start and before I could take one step the counter stops :PIf it works like i think it works, this feature is useless for running…

    Hi DC,

    Would you know if the timex device agent will work on android apps?

  234. No, there’s no method to download from the TGT to Android directly. The challenge is that Timex didn’t implement ANT+ downloads (usually via ANTFS), so you’ll have to use the USB cable to download to your computer first via the Timex Device Agent.

    Hi DC or anyone,
    I’ve got my TGT for 2 weeks now, but is not entirely happy with its performance. First off, when I turn on the watch to get GPS, the TIMEX logo would always appear on the screen and stay there like forever without getting any GPS signal. I had to turn it off and on again before it starts trying to acquire any signal. Next, I managed to download data from watch to computer without problem for the first week but now I’m getting an error msg telling me to check connection. Please advice, thanks

    Hi DC,

    I recently got a TGT after my Garmin 305 went dead on me. After using it for 2 weeks or so I must say I’m quite disappointed with the GPS accuracy(using the 305 as the benchmark. The current pace displayed can be off by as much as a minute or so even in open areas. I’m wondering if I have all the settings correct and whether other folks have experienced the same, By the way my firmware is the latest version.

  237. @Anonymous
    Timex software is crap. The Device agent is a joke and loses connection very often. The online free version of Trainning Peaks is a joke and WKO+ is primitive and definately not worth the cost..

    Satelite acquisition varies. Sometimes it locks instantly, sometimes on the same place it takes 1-2′ to lock. The GPS is very inaccurate, I run on track and have the watch take 100m auto lap splits and it just can’t split on the same spot.

    Have you tried the auto lap split based on distance? I set it to auto split every 100m and what I get is 99, 104, 102, 100, 103, 101 and so on…. Why can’t it split correclty?

  238. Hi Eaglos-

    RE: TrainingPeaks and WKO+

    I think it depends a bit honestly. If you want ‘pretty’, there are tons of online suites that are way prettier (i.e. Strava, etc…) than TP or WKO+. But, each of those has it’s challenges when looking at data that’s not just run or bike. For example, Strava handles run data poorly, and others are better at running. Yes, TP and WKO+ look old.

    When it comes to data and analysis however, virtually nobody beats those two, except Sport Tracks and Golden Cheetah. And I’d say ST at default settings is generally equal to TP, and GC as-is beats TP in cycling, but fall far short in running/swimming.

    What other apps would you recommend?

    RE: Accuracy

    At the points noted, you’re below the accuracy level of the unit. GPS units are advertised within about 2-4%, and offhand the unit is within I think 10 meters (advertised). So being a meter off is pretty good.

    Now, as to why it just doesn’t call it 100m and ignore the actual, I don’t know – I’d suspect because they decided that based on the per-second split they’d show the distance. Meaning, they either had to round distance to the nearest meter or round time to the nearest 1/10th of a second, and it was easier to simply show the distance as-is. Though again, we’re talking levels far below GPS accuracy rates (for consumer grade devices – for military, aviation, and industrial grade it’s different).

    Hi after reading your in-depth review I bought this watch and have been used for 2 weeks. I an fine with the GPS accuracy and searching time. However, I have a little problem here, I don’t know how to use the interval timer although I have go through the user manual! I mean I have follow the menu to set an interval timer, but I don’t know how to activate it in the performance mode! May you help me at this point? Many thanks!

    • Gonzalo

      After searching and not finding much info on the web and do several tests, I believe that the way to use the intervals in the TGT ends up being quite simple.
      After you create a time interval and give it a name (for example Fartlek1), only we should select “Fartlek1” in any of the fields (1-4) of the display performance mode. Then, when you start the chrono with the start button, this field starts the sequence of intervals that we created previously, emitting an acoustic signal of 10 seconds to the exchange of interval.
      I hope this is the solution because it really didn’t find much information and with this working properly.
      Regards. Oso.

  240. @DCrainmaker

    Regarding software, the question is which one supports timex data files. So far I have played around with Golden Cheetah and Sport Tracks. Their user interface is far better than WKO+ but I cannot comment on the functionality just yet.

    As for the auto split issue the general problem is that a 200$ flagship training device lacks a centisecond counter found on a 60$ track watch.

    The other problem is that you get both a rounded time AND a false distance estimation. You run 100m on 18.45” and the watch records 98 on 18”. You run 100m on 18.72” and the watch records 102m on 19”….

    Of course this is a “triathlon” watch where there is no logic in splitting over short distances and going off by 2-3m every 10.000m splits makes no difference. Nevertheless I wish it could take proper splits.

  241. @Elvis

    I understand that timers are just another piece of data like speed, distance and so on. I think that you would have to add them to the data screens of your workout in order to use them.

  242. Elvis


    Thanks very much for your reply. I have added the timer as 1 of the 4 data displayed on the screen but I found that the HR alert will not automatically adjust according to the timer setting. Neither any of the data option can show the target heart rate zone of the interval. Is it true? If so, the interval timer is not helpful at all…

    Timex just released another firmware upgrade for the Global Trainer on 5/30/2012. More improvements in satellite aquisition, accuracy note in the release notes.

  244. Elvis


    Thanks for your info. I have updated the firmware.

  245. I bought a timex global trainer and noticed it wasn’t precise while riding my mountain bike this past weekend. I rode the same course 3 times, and found three different distances (6.98, 6.51, 6.44 miles). The course is known to be just under 8 miles. It was quite wooded, but I made sure that the signal was acquired before I began riding. I am going to try pairing it with the garmin speed/cadence sensor to see if that fixes it, but if not, it will be going back in favor of a garmin.

  246. Jose Luis

    I was not decided to buy this one until I read your post.
    As I am a Spanish speaking person, it took me a while to understand every technic word in here. But it did worth the time. Your writing kept me hooked until the end.

    Now, I will buy the TGT and continue training with it. Can’t wait!

    Thank you DC Rainmaker !!!

    Hi Ray.

    I’ve had my Timex Global Trainer for more than a month now and this morning while on a bike ride I found that the distance data was off by 3kms! Yup 3kms. I checked this against my wife’s 910XT and my Cateye Velo 5 cyclocomp. Further to this, my heart rate monitor showed elevated heart rates on my way back. It showed a spike of 213bpm! I am wondering if anyone else has experienced this with their TGT or issues like mine are common with the TGT. Thanks a lot. 🙂

    Is there any chance you can put a request into timex?

    I have two bikes and two speed/cadence sensors. Right now, every time I switch bikes, I have to pair the ANT+ sensors again. Timex already provides for Bike 1, Bike 2 functionality, why not save the sensor pairing so that when I switch from bike1 to bike2, I don’t have to pair the ANT+ sensors again.

    Much appreciated.

  249. How can one add a “average” pace to display in the main Run section (say to replace the HR)?

  250. @Greg

    Either from Device Agent software or by pressing the Enter button while on your selected activity (run, bike etc) and then selecting Displays and then telling it how many you want and finally choose which ones you want.

    @beachdrifter – Dennis
    The GPS does not work well, don’t use it for distance while riding your bike. I only use it for speed and even then only as an estimate.

    I updated the device using the firmware that was released on 30th May 2012. GPS aquisition was extremely fast and for the first time it aquired satelites while inside my house.

    The bad news are that I can no longer connect it to my PC 🙂 Device agent sees the watch initialy but if I press Download or Settings the watch displays “Tranfer Complete” and Device Agent displays an error “cannot find the watch” or something like that.


    After spending a month with WKO+ and Sport Tracks I would say that I dislike both of them. They seem to be written by programmers for programmers, especialy WKO+. Simple tasks like modifying a lap are tricky or not available at all…

  251. Yeah, WKO+ is pretty crusty UI-wise.

    ST is better, but agree it can be confusing for non-computer people.

    On modifying laps, very few progams out there allow this (in fact, really none that I’m aware of). Some allow creation of your own laps, which is what ST does – you can basically just override them.

    I wish there was a better story there.

  252. Dennis

    @Eaglos – thanks for the heads up 🙂

    @Ray – any chance Timex will come out with a firmware update to include Time Alerts? I base my nutrition/gel intake on time alerts.

    Thanks and more success!

  253. I wouldn’t count on it. Timex updates are very few and far between.

  254. PilotFishBob

    @Eaglos – I had the same problem at first, seems that Windows got confused about the USB connection. I went into device manager and removed the TGT’s USB device, then re-plugged the watch and let it rediscover and install. After that I had no issues.

  255. Yet another update.

    Another minor issue I have found has to do with alarms. For example, if a lap split or a timer alarm goes on you have to press the stop button twice in order to stop recording your lap…

    This is very frustrating if you take into account that a) Timex buttons have a very vague feeling b) Lap/Time measurement gets even more off the mark and c) Lap/Time editing is nearly impossible.

    Another thing that I have found has to do with timer repetitions. In my mind, if repeat = 1 it means that the timer runs once and then repeats itself one more time. In Timex logic though, repeat = 1 means that the timer runs one time and than it stops, so there is no repeat 😛

    In order to have the timer repeat one time I have to set repeat = 2.

    @Dc Rainmaker
    Do you think a footpod whould be more accurate than the GPS?

  256. It can be more accurate, but it can also be off more. It really can be incredibly accurate (with proper calibration), or it can be way off. In general, I find GPS more accurate, but there are certainly cases where you can really nail footpods – it just takes more work.

  257. I got this watch as a back up. I have a 310XT and a 910XT (noticing a theme here), but sometimes running friends or pacers for ultras wanting to see the bene of GPS ask to borrow a watch…yeah…not gonna happen so thats why i got this one. for the price and the functions its solid, just something different to get used too

  258. Ali

    Hi DCrainmaker,

    Great review, you are the authority for this space.

    A quick question, when is the TGT2 supposed to come out?


  259. Question: I’ve never trained with anything more than a regular watch (stopwatch function mostly) so when it comes to finding splits, gps being off by a bit, or calibrating power meters on my bike…I have no idea. I just took up triathlons as a hobby/way to stay in shape now that I’m 30. Will I be totally disappointed by this watch? I mean, all of the negatives are things I don’t have already and am not sure what they are for, so I won’t know I’m missing them right? I like the multi sport mode ease of use and the big display, so is there any reason a TOTAL NEWBIE should not buy this one?


  260. Thank you for the great review !
    I read everything about gps watches and you are really helping a lot with your true reviews . Thanks again

  261. Thank you for your great reviews !
    You are helping so much to choose!

  262. Hi thanks for awesome reviews – they are so detailed that I get totally overwhelmed and frankly scared of the machine I bought ( Timex GPS Ironman) – I have a very simple question as I am setting up the watch and the training software- how do I get them both to recognise everything in Km ? I just can’t handle miles and my training plan also is in Km. Many thanks

  263. Tom

    I’ve been running for awhile with the Global Trainer and really like the watch except for one thing. The metal clasp on the watchband is horrible! Seriously, what was Timex thinking? The clasp digs into the wrist skin pinching it against the wrist bone. I don’t have it set outrageously tightly, just comfortably (at least at first). After a couple miles it starts to sting, and by 16 miles it is painful.

    I expect more from the watch band on a watch made by a real watch company. If Garmin messed up on the watch band this badly, well, they’re just a GPS company, so oh well. But Timex? Very disappointing!

  264. Anonymous

    Does anybody knows how to change current date and time for this watch?

    I don’t found it in user manual and in Device Agent.


  265. Great review! It convinced me to buy the device with the heart rate strap. A few things I have noticed about it:

    Training Peaks is an amazing software system, and I have not felt the need to upgrade to Premium.

    The pace graph is all over the pace on TrainingPeaks, just switch paced smoothing to high, and upgraded firmware, so we will see how that changes it.

    It worked very well when I was biking in the park. Speed and distance seemed very accurate and the map was exact.

    When running a tempo run, my teammate’s 410 was recording the mile splits earlier than I was, and getting slightly faster mile splits. May have been due to corners being cut off, but I don’t know.

    It is now only $144 on amazon so I think it is worth whatever minor flaws it has. That is so much cheaper than any comparable device.

  266. Hi DCR – I have read practically all your reviews and on this Timex review read almost all the comments too. I have a big problem- my Timex Ironman which I bought about a month ago and have used about four times – just plain refuses to lock on to any satellites – irrespective of time of day I run or route I choose ( all outdoors by the way). And yet when I come back to my apartment and step out on the balcony it seems to lock a satellite ! ( I live on the 18th floor of a tall building) !
    What use is that to me ? Can you please tell me if I need to update some firmware or reset the watch to default settings ( how does one do that?) or should I just dump it back on the shop? Very frustrating – esp if it says no GPS and yet shows a speed – how can it do that?

  267. DC Rainmaker thanks for the great review and thorough work, much appreciated. I am trying to turn my .pwx file into a spreadsheet, any ideas on a key to XML timex has used to carry the data? trying to save my self some time…thanks for you time rock on

  268. I’ve decided to buy the Timex global trainer. I only run but it was at such a good price point and I find the virtual trainer a useful feature. It is also a huge watch (bigger than the 305). I believe I have made a very stupid decision

  269. The watch standing alone is a great item. I love the customization and all the great things this watch is able to do. However, knowing now that it’ll cost me $120/year just to view the data from my workouts I would not have purchased this watch. When you upload the data to the website Training Peaks, it is clunky and difficult to navigate. The lack of customization in your personal account completely contrasts with the way in which this watch works. You are able to use a free account to view your data, but this is almost useless because any of the important data you would want to track is only available in the premium account for $120/year. I had owned the Suunto T6C and even though it was not GPS it had a much better interface and way more data I could track – there was no website to go to. All in all I am very disappointed that I spent all this money just to have a mileage counter on my wrist.

  271. John Stone

    I nicely disagree with Le Hiep on this, the basic free version of Training Peaks is just fine for viewing plenty of data. Since the latest firmware updates I have no issues. I bought the watch used a while ago from a person who said it “never found sateilites” and “wasn’t easy to use”. Haha well duh, she didn’t have it updated.

    I have no issues with it tracking my swimming, works great for running, as well as my biking in wooded areas.

    Come on people! That’s so simple to fix. And as for user-ability, well, this watch is as easy as it gets. Great watch, i got it for $98 used on Ebay with free shipping and that included the Heart Monitor. Couldn’t be happier.

  272. Viki Saigal

    Hi DC
    I have a query about how GPS functions w.r.t distance. The other day in the middle of my run I got caught in a massive tropical storm. I ducked for shelter hoping it would pass in a few minutes so I did not stop the GPS Global Trainer. However, the storm lasted for about 25-30 minutes. Whilst I was totally stationary during this period I noticed strangely that the Distance on the watch kept slowly ticking up to the point it had added almost 1.5 km’s in the 25 odd minutes that I was not running. Why is this happening ? Its rather odd that even though GPS is on and I am standing still the watch continues to add distance !

  273. Harold Ennulat

    Is there more than one version of this watch (Timex IronMan Triathalon)? The one I have came in a box virtually identical to the one shown in this blog post, but it does not have the Start/Split buttons on the bottom like the one in this review. The part number on mine is T 5K575 F5 .

  274. Nick Fournier

    I’ve been using the TGT for a while and generally like it, however the speed/cadence sensor on my bike has started acting funny. Essentially it’s returning speeds that are really out of whack.

    Is there a way to make the watch use GPS for speed and distance and just report cadence instead of using it for speed, distance and cadence?

  275. H2Obro

    Great review DC Rainmaker. Thanks.

  276. Dr. Ted

    Hi DC Rainmaker,
    I currently have the TGT and recently purchased with Timex cadence/speed attachment for my bike. I hate it. Can you recommend any other cadence attachment that works with the TGT? Thanks for your thoughts.
    Dr. Papenhagen

  277. SimonW

    Hi DCR,

    I’m considering buying the TGT as it seems to have come down in price here in the UK. I’m actually trying to decide between this and the FR410. From reading your review as well as other less informative reviews, I’ve picked up that a lot of people are not satisfied with the GPS reception. However, it has been over 2 years since your review so would you say that this is still an issue (a significant enough issue to push me towards the 410?)

    Thanks, fantastic review by the way.

    • ChaoW

      I just got the TGT yesterday, and tried to establish a connection with a satellite in the afternoon (it seems it is the only way to adjust the time.) The signal was still not great, but I eventually managed to locate a satellite, and it took about a few minutes which was normal according to the manual as it was the initial connection. I live in a uptown neighborhood in a major city in Ohio, US btw. But other than that, am pretty happy with it.

    • Anon

      I second the request for update since firmware could have improved GPS (or any other weaknesses) for TGT. However, in his recent (Nov) 2012 Sports Gadget Recommendations (link to dcrainmaker.com) he recommends the TGT as Triathalon Watch Budget. To me that infers that it has acceptable GPS (for the price range).

    • Simon Woods

      Thanks for your input, I’m definitely tipping towards the TGT. To me it seems the perfect multi-sport watch for the price.

  278. owen

    hi, what’s the size of your GF’s wrist? i, too have small wrist and 5’4″ in height. my wrist is about 6.5 inches in diameter (i used a tape measure 😀 ) and i’m planning of buying TGT, but having 2nd thoughts because of it’s size. thanks very much…

  279. Harris

    I’m in the market for a new hrm (with gps) and have a (luxury ) dilemma. I’ve been a loyal polar user for about 15 years, going via an M71ti an S610i and my current RS400 with s1 footpod. I “played ” with Timex’s first gps speed+distance (around 1999/2000) for a while but given that the gps module was pretty huge and there was no hrm, that was kinda short-lived and is now gathering dust.
    My problem now is that (a) My RS400 has been back to Polar 3 times already for warranty issues, so while it’s a great piece of kit when it’s working, the love affair is over(b) The Precision Performance software which was excellent with analytics etc seems not to be supported any more and the web-based Personal Trainer seems a step backwards.
    I like the look of the TGT or the run trainer (most of my training currently is running ) but I’ve tried the basic TP software and quickly saw that a lot of the things i’d want to see were part of the premium paid version (not happening ). This leads me back to the relatively expensive Garmin FR610 or Polar RC3 and the RC3 lacks much of the flexibility of the others. Is the timex TP version more comprehensive than the basic, meaning I’m dismissing the significantly cheaper TGT and run trainer too quickly, or should I just suck it up and pay the extra for the 610? Lastly, how do you rate Gaming connect vs Polar personal Trainer and the timex TP?
    Your reviews are hands down the best i’ve come across, telling us the things we really want to know in an unpartisan way! Keep it up – DC rainmaker is now bookmarked in my browser!

  280. Marcel

    First off, great site and reviews. I wasn’t sure as to which type/brand to pick up but after reading all your reviews on the ones that interested me (FR110/FR210/FR410/TRT/TGT), you helped me make up my mind. Picked up the TGT with heart rate tonight, setup was easy, (partly because of your review), no issues with anything, quick pickup and having my first run in the morning. Have to mention that I got a really good deal on it also.
    I am however dissapointed in the “free” version of trainingpeaks though. Should have paid more attention to that part. Oh well.

    • Eaglos

      This is the biggest drawback of that device. You pay premium to
      buy a computer (not a watch) and you cannot get the most out
      of your data.

  281. Mike

    Anyone who owns the TGT, while running or biking, have you ever had the screen freeze and the only thing you can do is hold the power button down to reset? any solutions?

  282. Eaglos

    Update on my (crappy) Timex.

    I left for summer holidays and when I came
    back (20 days) the device would not charge.
    Since there was no point in paying (again) 30
    Euros to revive it, I decide to break it apart.

    I was unable to find the triangular alen that is
    required to unscrew the back so I had to improvise.
    The battery is a Sanyo 600 something mAh which
    there was nowhere to be found on the market
    despite being “a common battery” as Timex told me.

    In the end I managed to install it with a third party
    1300 mAh battery (lots of drilling and improvising).
    The device still charges whenever it feels like it and
    so I will have to make a separate charger fot the battery…

    I am extremely happy that I did not throw away the 300-400 Euros
    that Timex wanted for this piece of junk. Next stop Garmin.

  283. Alasdair

    Great site, great reviews, was just wondering how the TGT deals with transitions in races and how it compares to competitors?

  284. Brian

    I am trying to install the firmware updates to my Timex Ironman GPS on a mac and have downloaded from the timex link for the download and when I try and open it I get a message that there is no default application specified to open the document. Any help on what I need to do to get the firmware update.


    • Rainmaker

      You’ll need to grab the Timex Device Agent, or the Training Peaks Device Agent. Then from there you’ll select the file from within that.

  285. andrea

    Timex GT is the biggest piece of crap I have ever bought in my entire life (at least so far 😉
    Bought it in 2011, basically it did not work decently till aug 2012 when the 4th or 5th firmware release was out: Then it randomly works. So, depending on the day, it fixes the sats quite quickly but still, often, half an hr after the workout has begun.
    I also have major concerns about the accuracy (both of hr and pace). When running with friend with garmin complete different values…

    Finally also the charging clip (or battery or something else) went broke and it does not charge anymore. So I am definitely pissed off and I am going to execute this rubbish toy with an heavy hammer

    Timex NEVER again! it is a shame for a company to market such a piece of crap!!

  286. Steven


    Thankyou for your fabulous review, they really help!

    I purchased the TGT in mid 2012 after reading your review and have generally been very happy with it. I’ve noticed a couple of things and wondered what your thoughts were on these:

    Swimming: Given that GPS on mode is not particularly useful for swimming (unless the watch is located in a swim cap), then is the best way to time a straight swim to simply turn GPS off and use it as a stop watch in performance mode? Presumably ‘GPS off’ mode deactivates the auto-start/auto-resume/auto-stop?

    Multisport mode: In light of the above comment re swimming, does the same advice apply for a triathlon that incorporates a swim? If so, then the watch only performs as a timer for all events unless one fiddles around post swim to re-activate the GPS after the swim leg, or alternatively, you place it in a swim cap and leave GPS on.

    Do you know if you can complete a triathlon wearing the watch on your wrist and with GPS on for the whole time? Presumably you would need to turn off ‘auto stop’ so that the lack of GPS signal doesn’t stop the watch from continuing to count time for each leg and for the event overall?

    I’ve noticed that sometimes turning the watch on takes no time at all (<1 minute) to find GPS and other times it can take up to 15 minutes or the signal bar goes up then down, up, down but never finds a satellite or at least not for a frustrating period of time. This seems strangely completely independent of prevailing conditions or line of sight to clear skies. If this happens, I turn off, restart, and most times it comes good again pretty quickly. Strange though!

    I have a Giant bike with Ridesense which pairs readily enough with the TGT. However it seems to have some form of conflict whilst in use. Could this be due to the device receiving for example speed information from both the Ridesense sensor and GPS and thus having two sets of data for the one metric (eg speed or distance)?

    Lastly a couple of things when next your talking with Timex!

    For us ‘mature’ folk, the font sizes of the TGT are quite small, even when they don’t need to be. Notwithstanding the flexible capacity users have re number of fields in display, they could do a much better job with the display under some of the firmware driven displays. For example when locking and unlocking the watch (which I use often due to bike gloves, and when MTBing or running), reviewing summary data , or changing settings. Generally they could make much better use of the display area.

    The indiglo backlight is also able to be setup with some flexibility. I find it useful to have the light go on each time I press a button, particularly in those winter activities! However once the watch is powered off, the settings revert to default. This necessitates one having to reset the setting each time the watch is powered on. It seems that this type of setting should be a user preference that is independent of the watch being powered down.

    • DS

      I also had trouble getting the Giant Ridesense to work with the TGT. Like you say, it would pair immediately, but when riding there were constant dropouts. Actually, there was more time spent in dropouts than “drop-ins.” It was useless, so I returned the Giant Ridesense and took the Garmin Speed/cadence off of my old bike and put it on the new Giant and it works well, provided the TGT is relatively near the s/c sensor — it’s almost like the ANT+ has trouble transmitting around the Giant Trinity’s frame, or maybe the Ridesense range is just very short.

  287. Brian G.

    With the new TRT already out, do you see a possible firmware update coming to the TGT ? I just want the nutrition updates if possible.

  288. Paul K

    I’m in the market for a new GPS watch and looking to spend up to £200. I’ve read all the reviews on your site (really entertaining by the way!) and it seems the TGT is a capable device. However, I notice it is coming up on 3 years old. Do you know of any replacement on the horizon? Or is the TRT supposed to fit this niche?



  289. faron

    I bought one of these last week and have used it on a 2 hour run and a long weekend of kayaking. So far the watch is pretty cool and is holding its own to replace my phone (xperia active) with endomondo as my GPS device for runs. I had the watch in GPS mode for about 8 hours and in time/off for the rest of the time over three days. The watch died at the end of the trip so there is about a weekend worth of outdoor activity in it which isn’t terrible but is a bit low.

    My only real complaint is that the GPS lock takes an age compared with my phone. My phone will latch onto satellites in about 10 seconds while the watch will take minutes and often asks if I would like to reset the GPS (no!). I’ve upgraded the firmware to latest to no avail. This isn’t a big problem as long as I start to grab a fix a few minutes before my run. Otherwise I’ll have some annoyed running partners.

    My most major disappointment is the lack of any kind of linux support for this phone. I dwell in linux almost exclusively and this is a major negative especially compared with Garmin which has great GPS support through GPSbabel. Further, the pwx file format is very poorly supported by third party software. I did find a site that will convert pwx to tcx here:

    link to beta.pwx.raytracer.dk

    And can use this to bring the route data to a usable format in endomondo.

    Those are my thoughts. The linux issue will only apply to a small percentage of folks, so I’m sure that’s not a dealbreaker for them. I’m still deciding if it is one for me.

  290. Julia

    I’m confused…you list this at a $150 price point, but in the pics (and the name), it looks like you’re referring to this $360 watch: link to timex.com
    What Global trainer is at the $150 price point? Is it this one: link to timex.com

    What’s the difference?

    • Rainmaker

      Same watch, just that the Timex.com site has never bothered to lower their retail price like everyone else has. Kinda funny, since the official MSRP is much lower these days than $360.


  291. John Runions

    Awesome review, much more information than other sites provide.

    I have the Garmen 410 and enjoy it quite a bit. Unfortunately I am one of those people who once put a watch on NEVER take it off. Means it needs to able to go in water (doing dishes, jumping the lake, …etc). This is the only point of the Garmin I do not like.

    Its seems that the Timex has “almost” all the features of the Garmen with the addition of being water proof up to 50 meters.

    My question is around the Performance Pacer compared to the Garmen’s Virtual Partner. How to they compare to each other.

    I run alone quite often around the same course. The Garmen allows me to run the same course against one of my previous saved runs. Letting me know if I am ahead of behind my previous times. It shows on the screen if I am ahead or behind my virtual runner.

    Does the Timex have a similar feature?

  292. Excellent review!
    someone could tell me where to buy the USB cable for this watch. I’ve looked on ebay and can’t find it
    my cable does not work, so I can not use my watch!

  293. Brian G.

    Just a quick FYI, Timex’s site does not appear to be selling the TGT (at least on their site). I have had this for 3 years and it has done a great job (being used almost every day). I was hoping that they might just do a firmware update to make it do a few more things but that really does not appear to be the case. Here’s to hoping for a new model to come out

    • Rainmaker

      Unfortunately I wouldn’t expect any further firmware updates on the current model.

    • Thanks. A friend of mine made the call to 1-800 to order the USB cable (10 usd). She’ll receive the device and then she’ll send it to me. It just a matter of time, around a week. Thanks again.

  294. I’d like to buy Garmin Forerunner 910XT but i am not sure about it….

  295. Dennis

    I just purchased this watch a week ago. I took it on a long bike ride today and it keep shutting off during the ride. How do I get the watch to stop turning off?

    • Rainmaker

      I’d ring up support. That’s not at all normal. It sounds like something might be loose inside, which could be getting bumped on the road.

  296. David

    Hi, great reviews. Does the TGT or any other GPS watch give map coordinates (British grid reference) or just a lat & long? I know that garmin 610 and 910 and fenix do as well as suunto x10 and ambit. Just wondered if I missed any before I take the plunge. I want to use it as an everyday watch, with all the training benefits of a garmin but occasionally use it with a map to pin point my location. Any other suggestions? I’ll probably go for the 610 I think.
    Thanks a lot

  297. Caesar Ziggy Q. Perlas

    I owned a Timex Global Trainer for two years. I used it for running every other day. I mount it on bike for a long ride during weekend. I never encountered a problem with it since I bought it until now because the watch’s strap was broken. The nearest Timex service center couldn’t do anything about it because they do not have stock. They said they’ll have to get the unit and then order the broken strap. Well, I didn’t agree with it and the worst is, I will have to wait for 60 days. Its a real life experience with Timex. I wonder if Garmin watches have a durable straps that could last forever. I was looking forward to replace it with Garmin because I can not used my Global Trainer anymore.

    I returned mine, because of the disappointing GPS. It’s almost impossible to get a fix in a reasonable amount of time, if at all or without resets. I always ran together with my good old Garmin which is much more accurate.

  299. Couch to marathon and now triathlon

    I am in the market to purchase a new triathlon watch and have been spending a lot of time reading your reviews of the Garmin 910XT and the TGT. I am very curious of your thoughts on a straight up comparison??? I have 400 bucks to spend so money is not the big issue, I just want the best watch to get me through my first ironman.

    thanks for the great review. hope to hear from you

  300. henrid

    Look how bad the TGT is:

    I already bought a tgt gps watch and am now getting into the training peaks website. I was wondering if it would be worth the money to upgrade to premimium. If i do upgrade it would be for a year to save all that money, so i really dont want to upgrade for a year and then find out it isnt worth it. I was hoping you could give your two cents on my thought process. I am only teen and dont have a lot of money, so buying ANYTHING is kinda a hard thing for me to do because i like to think I’ll buy a car here in a few years when Im 16 and get my temps. But I also am a very dedicated runner though, and currently run around 3 miles a day, do some lean muscel building, plyometrics, biking, swiming, and LOTS of other cardio throughout the week when im not at work, so i dont know if i should upgrade that way i can get more information and to train with, or if i dont really need that info. and i should just use what is already given. One of the major things I would be looking foreward to if I upgrade would be the online coach, that way since cross country season hasnt started yet, i could incorporate a little more of a structured athletes type of training into my schedule, rather than repeating my daily 3 miles, which i know will eventually lead to a plataue… so is the trainer actually good quality or does it just state the obvious that i already know? I’m sorry for this post being so long, this is really important to me, considering how much other time and money I have invested in sports,particularly in run training, and because my money is so tight right now (im not poor, just a long term thinking penny pincher). I also want to thank you for this in depth review, its the reason i bought the watch. HELP IS MUCH APPRECIATED, IF IM GOING TO BUY IT NEEDS TO BE SOON BEFORE CROSS COUNTRY SEASON. THANKS AGAIN.

    • While TP is very good for analysis, based on what you’ve outlined, I wouldn’t spend the money. I think the money could be better spent in a training plan (even a free one online) – that would result in bigger gains. From a free software standpoint, there are tons of options as well, including Sport Tracks for the 2-plugin trial mode, if you want more detail.

      Good luck!

    Mr. Ray,

    2013 is the year, with Suunto 2/2s, TomTom, targetting multisport athletes. There was already Garmin 310/910.

    And recent the TRT2 has been updated into smaller formfactor…

    Do you expect Timex to announce multisport update any time soon?


    • I don’t know (and I don’t have a unit in test).

      In general though, if a company doesn’t announce a tri-focused product by Spring, it tends to get held until later in the year (Christmas/January/CES). At this point, announcing a tri product would essentially be a loss of 9 months of R&D for next year.

  303. jim

    a great, in-depth review, thanks
    i have an out-of-the-blue question, does the watch/software produce a heartrateover time chart? i would like to record my heartrate while i sleep, with a chart showing bpm at each few seconds for the whole night. this would indicate a moment of anxiety. also, when i wake up my heart goes extremely fast, too fast to count, and i need to know what the time/duration is. any thoughts?

  304. Brent Beresford

    Hello, I just recently updated the firmware in order to be able to use a footpod. Is there a way to display my run cadence at all? I don’t seem to see this option anywhere, though I can set an alert for my run cadence min and maximums..weird. Thanks

    • Brent Beresford

      Oops, forget that comment…I had two footpods in too close proximity and so my watch paired with the one that was still in the box…so it works and all balance is restored in the world…

      p.s. thanks for this great review–help me a lot last year when choosing my watch!

  305. Ben

    Can you use this watch as a 24/7 ‘watch’ as well as a training tool for triathlons?
    I like the Garmin 910 but with a battery life of 20 hours, you can’t use it as a daily ‘watch’

    • Yes, no issues there.

      However, note that the TGT is really darn big – bigger than the FR910XT. The marketing makes it look much smaller than it is in real life.

  306. This review is really a classic! Kudos for still answering questions after all these years, Ray.

    Have you or anyone else noticed that the TGT may be discharging if left connected to a computer on standby? Mine had a full charge last night when I closed the laptop. I pulled it off the USB cable this morning but it was almost dead when I went for a run later. (I leave the display off to conserve battery).

    • I think I saw something like this once before. The unit was attached, but since the computer was in standby, it wasn’t providing power. More importantly of course was that the unit was still in the on-mode, rather than the typical watch standby mode.

      For fun, plug your computer in for a few minutes, then kick it into standby and see if the watch goes from charging to off, or charging to staying in the on mode.

  307. Tom

    I bought this and am trialling it at the moment. I’m not especially happy with it. The distancing algorithms aren’t great – perhaps due to 2 second sampling?. As evidenced in your accuracy review it can be 10% short if lots of zig-zagging movements. It’s probably not an issue in most cases, but it’s annoying knowing it does it.

    More irritating for me is the overreporting of distance when stationary. Last night I reset the watch and placed it outside with a clear view of sky. Hit start. I came back this morning, 10 hours later, and it said 7.7km! It is adding up every GPS fluctuation to the total, and slowly ticking over like a car odometer. I am sure my garmin never did that. My phone gps doesnt.

    Also, no speed smoothing option. Only pace smoothing, which is irritating. The speed display fluctuates a lot more than the 310xt. It’s annoying seeing the speed fluctuate +/- 2 kmh on the TGT, whilst diplaying to 3 decimal place “accuracy”! For future reviews it would be great if you could comment on whether devices do speed smoothing.

    Finally, you can’t shut it up! It beeps when you turn it on, beeps when you push start, beeps when autolap is triggered, beeps when low batteries, beeps when gps is weak. When no silence option?

    I should have bought another 310xt, or a 910xt.


    • You’ll find that for static locations like that, that pretty much all GPS units do the same (sport), as they’re really designed more for movement. The challenge with GPS is that accuracy fluctuates, thus resulting in slight movements of true location.

      You’ll find your Garmin does the exact same – slowly ticking up. But that really has no bearing of accuracy while moving (i.e. running or cycling), as you can see in my various accuracy test posts: link to dcrainmaker.com

    • Tom

      Thanks for the reply.

      I’m sure my 310xt didn’t slowly tick over like that. Are you sure all GPS tick over like that? We’re talking almost 1 kilometer an hour!

      From memory my 310xt didn’t register motion below a certain threshold, and speed will snap to 0.0kmh when it decides you’re stopped.

      I could be mistaken of course. I’ll check on my next 310XT.


    • Yup, absolutely sure. The degree to which each unit does it varies based on the unit and conditions, but they all do it.

    • Tom

      Ok, if they all tick over slowly then I take back that criticism about the TGT.

      I’ve used it a bit more now and it’s growing on me. The accuracy over real distances and training routes seems much the same as my garmins, within 20meters or so of the true distance over a 10km course that I regularly do.

      I agree with the comments about font size though. I use it when surf ski paddling and the drops of water that end up on the screen obscure the digits when in 4 panel display. Shame they give so little of the screen real estate to the numbers.

  308. Ray, thanks for the feedback. Impressed that you still remember how the TGT works. It looks like I had the watch ON instead of OFF so it wasn’t charging even with the laptop ON. It’s a double-whammy because when you put the computer in standby the watch stays ON and discharges. I believe there is a timeout after no movement but I’m not sure.

    At least I verified that TGT doesn’t turn back ON (while OFF and charging) when the attached computer goes into sleep mode.

    We spoke once about custom flash settings for the TGT. I wish I had tome time to play with that because a few updates would improve the user interface. I can’t imagine that Timex will be spending much time on the TGT.

  309. Steven

    I have had this watch for about a year now and WOULD NOT recommend it. 10% of the time the watch finds a satellite within a few minutes, the rest of the time it takes up to half an hour even ona clear day with line of sight to sky. Resetting the GPS or switching it off and then on makes no difference. The next time it finds within a few minutes, so no consistency. Won’t be a problem shortly as this frustrating device will be recycled as part of a concrete wall shortly! Hoping garmin has a reasonable level of reliability

    • Alan Canfield

      Hey, Steven. Sorry to hear about your problems. I’ve had the TGT for about six months and haven’t experienced 30 minutes with a failure to lock on to GPS. I’m sure you’ve tried the standard stuff, including the latest firmware update through the Device Agent? Sometimes I set it outside before going on my run, but it’s probably a matter of time before someone walks off with it (happened to a friend of mine with his Garmin 500). It is pretty aggravating but the watch does have a lot of features for the price.

  310. Steven

    Thanks Alan

    Glad your having a better experience than me. My habit is now to take the watch outside, turn it on, come back inside for 5 to 10 then hope the watch has found a satellite. It seems that if it struggles the first time, then almost no amount of resetting and switching off then on will make a difference. Have tried the firmware updates but they don’t seem to make any difference.

    Was also impressed with the price/features and also timex reputation. Just wish I could turn it on, pick it up within a few minutes and get on the road! Perhaps that’s too much to ask!

  311. Tom

    Steven, I haven’t had to wait 30 minutes, however the rest of what you say is familiar – needing to wait 5 to 10 minutes at times. It’s very inconsistent when it comes to GPS lock.

    Get a garmin 310xt or 910xt. I’ve gone back to a 310XT (my first one died), and it’s so much more reliable and trustworthy than the Timex. It just works.

  312. Steven

    Thanks Tom

    30 was the max I have experienced so far, typical for me is similar to you (5 to 10). Very frustrating! Garmin it is! Appreciate the comments/recommendation

  313. John S.

    I have never had issues connecting to satellites. I simply place it on top of my car that’s in open air, do my stretches/warm up ( a couple minutes) and I come back and its ready to roll. Once or twice I have had to turn it off and on again, but nothing big.

  314. Edward Stavin

    a ways up you wrote >>Finally, because many folks compare this watch to its two primary competitors (the Garmin Forerunner 305 and Forerunner 310XT), I’ve broken out all the details below:

    Then you go on to show a table that has nothing to do with these competitors. Any chance you can fix it or send me the table?

    Many thanks.

  315. Jim Szczygiel

    I’ve been switching back and forth between Garmin’s and Timex for years now
    Currently using the TGT and even with the most recent update I was a little surprised
    to discovery that the TGT won’t display HR or Power Zone only actual HR or Power.

    I realize that they have zone alerts however I am not much into all that clacking and beeping
    while I am running.

    Am I missing something? Is there a way to get around this so I can see what Zone my HR is in
    rather than the actual HR?

  316. Eric Baylon

    Hello DC,

    Im not sure if I found it here already but Is there a way I can join info from the 910xt and TGT in one say garmin connect?



  317. Alan

    Eric, you could use Golden Cheetah to append one file into another, export the file, then upload it to Garmin Connect.

  318. Theodore

    you said that:
    Workouts: Create/Follow custom workouts Yes

    how can i do this?


  319. Theodore

    thanks for the answer but i cant find it. i have installed timex device agent 3.0 and i can change all the settings of the watch.
    where is the option to upload a workout??

    Please help because i am very disappointed with the watch.

  320. Alan Canfield

    Theodore, I’m no expert but I’ve been using the TGT for about a year. I believe the only way to really upload a workout in the TGT is through the Settings, Navigation tab in the Device Agent by adding individual Waypoints. This is obviously very cumbersome and I’ve never tried it. I assume you could use any mapping software like Google, RidewithGPS, MapMyRide, etc. to map a ride/run and then enter the key waypoints. This is definitely a legacy method.

    You can map out and save Workouts in Training Peaks but I don’t think you can upload those Workouts to the TGT device. At least in the Plus account service that comes with the TGT it tells me you need a Premium Training Peaks account to export workouts to GPX or similar formats. Even then, I don’t see how you could upload them to the TGT.

    Not sure this is much help but check out the Waypoints entry in the Device Agent Settings, Navigation tab.


  321. Theodore

    i create a workout at TrainingPeaks (online application) with specific time of warm up, some time of rest and the basic workout lets say 40 minutes.
    is there any way to upload this workout to the device.

    that is what i am asking for. thanks for trying to help me.

    • No, you can’t use the online app to push it to the TGT. You’ve got to use the Device Agent to build the workout and push it to the TGT, and then on the watch switch to workout mode.

  322. Theodore

    use the Device Agent to build the workout???
    on the watch switch to workout mode???

    i use timex device agent 3.0 and i cant find any option od build my workout.

    on the watch i cant find the workout mode.

    i cant understand anything.

    • 1) Connect the watch, ensure the watch is powered on and in “PC Sync” mode (press the mode button)

      2) Using the Timex Device Agent (or Training Peaks device agent), select Timex Global Trainer and tehn press settings.

      3) Select the “Performance & Multisport” tab. Then the “Timer” subtab, then finally, the “Timer 1” tab

      4) Select the bubble next to “Interval Timer”

      5) Create a new interval set – the name doesn’t really matter

      6) On the left side, you can add in additional steps, each tied to a specific HR zone. Those zones can be set using the “Configure” tab at the top, and then “Heart Rate Zones”. Then save to the watch.

      7) Once on the watch, switch to Performance Mode, then press Enter and select “Timer” before selecting the Timer # of your workout.


  323. Dirk van Hoek

    The watch was a disappointment, or better the lack of service. The GPS was okay maybe 1 out of 5 times a training without GPS. The HRM transmitter was broken after 2 months so I bought another transmitter. I also had it on my wrist during swiming, however the first time I used it during a triathlon the display had waterdrops on the inside and the watch was not working anymore. Feedback from Timex was when I send it for repair that the watch was not damaged. So I probably used the buttons during the system and it did not fall under warranty. I am pretty sure I did not use any button on the watch during the swing however wearing wetsuit and being in a group of swimmers during a race it might be that somebody else be accident hit the watch.
    Conclusion: I bought a triathlon watch which I cannot use in a triathlon, time to switch to another brand.! It was probably cheaper to buy a Garmin immediately.

  324. Theodore

    Rainmaker many thanks but….!!!!
    i followed the 6 steps and then i switch to Performance Mode, then i press Enter and i select “Timer” and then timer1
    how do i start this workout?? when i press enter i see edit or change name

  325. Twinsen Chan

    Thanks DC Rainmaker. I bought one 2 years ago because of this review.

    The watch worked well, but now i have a big problem……the watch failed while updating, now freezed and can’t start up.
    This happened when i updating it to 3.21, the device agent freezed, so i have to close it so as the update process was forced to stop. I am using Windows 8 and followed the instruction on “Disable Device Driver Signature Enforcement “.
    What can i do to reboot TGT? Are there anythings to do beside sending it for repair? Thanks

  326. Denney448

    Have you heard anything about a new version of this watch? I tried to pull it up on Timex’s website to read some of their stats, and there is no webpage, or it tells me I am not authorized to view it.

  327. Clement C

    Hi! I’m having this issue while I was running with this watch.
    While I was running halfway, the GPS signal was lost, and it was not able to acquire back the signal.
    Anyone is facing this issue? Is there any way to settle this problem?

    Or is there something wrong with my watch? Need help here!


  328. VJ

    Hi Ray,

    I am a beginner and wanted to choose between FR 10 & TGT. Considering both are available at the same price. Do you suggest FR 10 over TGT considering the release dates of these models?

    In my view, even though I am beginner, TGT is a great product considering the price, but I am little concerned as it seems to be a dated product.

    Kindly advice,


    • Very different devices. That said, at this point I’d consider looking at the FR310XT instead of the TGT. In general, people just have less problems with it, and you can usually find it for about $190 these days.

  329. VJ

    Hi Ray,

    Thanks a lot.. Primarily looking for a running watch.

    I will stick with FR 10 then. Are there are any other devices that you want to point out??



  330. Aigars

    I’m thinking to buy gently used TGT, but without bike mount, but I have Garmin Forrerunner bike mount. will TGT fit with Garmin bike mount?



  331. Mauricio

    This watch is no longer available at the timex website, do you know if they are planning to introduce a new model?

  332. Clement C

    I tested my watch again. I ran a half marathon, and the signal was lost at 12km marker. I realized that when I run in a place with a lot of tall buildings, trees or mountains, the signal will be lost and unable to acquire back. Sometimes, I can’t even get GPS signal at all before run even though I turned it on like 30 minutes before the run.

    After updating the latest firmware, it doesn’t solve this issue too. Is there any way I can strengthen the GPS signal or is it possible that my GPS chip is having problem? Any idea how to fix this?

    I’ve tried to email Timex and they asked me to send the watch back for service. I bought the watch in US, and I’m living in Malaysia. That’s the very huge problem if I wanna send it back for service.

    I wonder should I open the watch myself and try to see what’s wrong. It’s very frustrated that my watch is just 1 year old.

  333. Dognews

    we had to roll clocks back 1hr my watch has not updated to reflect the time change im still one hr ahead. recently updated firmware and still no change. am I missing something?

  334. Aigars

    I bought used few days ago. I’m so excited. This ir my first GPS sports watch. I was worried about GPS signal and battery, but not so bad. In the first day I test my TGT 11h, 4h use with GPS, all time HR belt was on. And at the end of the test battery indicator show ~50%, I thing it is OK. In cold start GPS was fixed during 2-3min, but in hot it takes few seconds.
    I spend 86$ on ebay auction + shipping to Latvia and custom duties, totaly I spend +/- 150$. In Latvia Timex not very popular, but used Garmin 310XT cost twice more, 910XT x3 as minimum.
    I think TGT is the best multisport GPS watch for this price.

  335. Slava

    Dear Ray,
    Thanks for review, it is very helpful indeed. In fact I bought this watch after reading your website, it helped me to make up my mind. I’m starting to use it and i will post my feedback after some time.

    In the mean time, Aigars from Latvia, can you please contact me at slava.fedorov@gmail.com, I have some questions for you

    Kind Regards,

  336. Brittany Norman

    I am in the process of getting my fourth Timex GPS Run Trainer in a year. Not because i love it, but because the first three stopped working. I replaced firmware multiple times, and that didn’t fix it. The first watch simply stopped acquiring a GPS signal and wouldn’t even attempt to catch a signal. You pressed the GPS button and nothing happened. Timex sent me a replacement watch and it was a non working watch, believe it or not. So they rushed me a replacement to that one, and it worked for about four months. Now it says it’s acquiring a signal, but it never does acquire one. And i live in a major metropolitan area (Fort L / MIami) Note that during a 12 month period, after shelling out more than $100 for this watch, I’ve been WITHOUT GPS function for many, many, many months. Pretty sad. Sending it for repair requires a VERY long wait. Here we go again.

  337. john Greece

    Hi everyone, i just bought TGP, and i have a small problem. While running i’m taking a split/lap (pressing the button or with ‘autolap’ on) , a screen-view with info about the lap is appeared, but it has only Tile-Lap and Time-Split info, no distance or enything else. Any suggestion? Thanks

  338. john Greece

    Thanks GADEMZ , i’ll check it soon

  339. Jude

    Can this watch track calories burned for indoor workouts such as Dips, Push ups, power band workouts? I guess the HRM should track all of that. Please do let me know. Thanks

    • Yes, it’ll track it based on HR, but nothing special for the components of the workout. It’s just HR driven.

    • Jude

      Well, as long as it shows me calories burnt and provides me with accurate heart rate beats I am happy. Will it be the same when it comes down to weight training at the gym. I’ve heard the fitbit has no HRM and you always need to hook it up to a smartphone or PC to read stuff. I want this watch over the fitbit. All I need to track is indoor workouts like routine in door exercises and outdoor running activities. That’s it. Will the Global Trainer do well in your eyes? Thanks

    • It’s the same with weight training as well.

      Yup, given what you’re saying – I think it fits the bill well. It is a bit large though, so do keep that in mind. There are units that are much smaller these days – such as the Garmin FR110 or FR210/220 that would also fit the bill.

  340. Jude

    Thanks, size isn’t an issue. I have fat wrists and currently use the DIESEL Mr. Daddy, so I am sure, this one is smaller than that! I’ll get hold of this one. When was the last this watch received an official update? And will the GPS etc all work fine in India, where I reside?

    Thanks again,

    • Years ago. It’ll work fine anywhere in the world (except a few points at the north and south pole), no problems there.

    • Jude

      Brilliant then, you’ve really been helpful 🙂 Does the watch need to be charged on a regular basis if GPS is turned off? That is using it like a regular watch for time viewing?

    • No, it’ll standby for weeks in non-GPS mode.

    • Jude

      And how about a battery change? Does this watch have more than 1 battery. Are they/ is it easily available in the market?

    • No, a single non-replaceable battery. Like pretty much all units on the market.

    • Jude

      Alright and now the million dollar question, for all that I mentioned, would this be a better buy over the fitbit?

    • For tracking heart rate based activities, yes. But for tracking steps day to day – no, a FitBit or other ‘activity monitor’ is a better choice.

    • Jude

      I’m new to these concepts. Have never tried them before. I need to check heart rate and calories burned for the following – jogging, weight training, cardio – treadmill, cycling and hand exercises, and the regular workouts like resistant bands, push ups and pull ups. Now I feel the TGT will do better than the FitBit. Hope I’m on the right track where my choice is concerned and sorry for repeating quite a few things again. Just that I need to pay import duty, etc which inflates the cost, hence asking so many questions. Thanks 🙂

  341. Cesar J.

    Thanks for the great analysis of TGT.

    I’m happy with it except for the 2% difference compared to other units. Saying that, when the weather is rainy, cloudy and in the mountains, the TGT is almost equally accurate than the forerunner 305 or 405. On the mountain, is more accurate than the 305 providing altitude data and distances.

    A few days ago I got in touch with timex, requesting an update of samples per second by the user (eg 1s, 2s to 5 seconds) which would give a significant improvement to this great model but for the disadvantage of light loss of accuracy and would make a good watch on the mountain.

    Timex gave me a response saying that there are no proposals for new updates to be discontinued. With an update as well, some perhaps would trust Timex again.

  342. Hi Rainmaker 🙂
    First of all Id like to thank you for your blog, Its great and I have been a big fan for over a year.
    Even though its 2014 and I already have a bunch of great training devices, all purchased after reading your in depth reviews of course I decided for pure nostalgic reasons to purchase a Timex global trainer two weeks ago.
    The reason of course the great price offer you can find on ebay (approx $120).
    After fiddling with the device and finding out that Training peaks is a little off for my taste and since I mostly use Garmin Connect, I decided to write a little service that would allow me to convert the .pwx workout files to .gpx and .tcx to be able to upload to Garmin Connect and to Strava.
    I would like to take this opportunity and share this tool with the community as I believe that it can help more of your readers who use timex devices.

    Please feel free to jump over and give it a try at: http://www.pwx2gpx.com.

    Again thank you for your great work and super in depth reviews 🙂


  343. khak

    is still worth to buy it ? Amazon offer 120 $. I need it for running, bike and GPS track recording ? Does last upgrade improve a lot ?

    • Tom


      Get a garmin (310xt or 910xt).

      I took a $120 deal for the TGT after my 310xt died. I gave it a good try, but it’s just too inferior to the garmin. I went back the 310xt in the end.

      In this instance you most certainly get what you pay for.


    • martin


      Thank you for respond and opinion based on your exepirence.
      Garmin 310xt on pictures seems very bulkley 🙁 Maybe forunner 110 ?

    • If doing a tri, get a FR310XT (not a FR110, since it’s not waterproof).

  344. David

    I bought one of these for my wife for Christmas 2011. She has never had a desire to download the data from it to keep a running log. However, yesterday she asked if she could use it to navigate a course. I thought, probably. But I cannot get it to connect with any of my Macs using either Training Peaks Device Agent or Timex Device Agent. Do you have any hints? I did do a firmware update and perform one test download when I first got it. But I have not tried again since. (And the computer that I tested it on has been replaced. But it was a Mac also.)


    • Hmm, that’s odd. I’d ring up Training Peaks support, as they own that piece (or submit a support ticket there). Sorry!

    • David

      I did contact them. They suggested cleaning the contacts on the watch/cradle, and trying a different USB port. I’ve tried a total of 10 USB ports on a total of three computers, all to no avail. (And I cleaned the contacts). I’m suspecting it is something like a Java dependency that isn’t working or something. I was just wondering if anyone is currently using this device with a Mac successfully. Hopefully on Monday they will have additional troubleshooting steps.

      Thanks for the great blog.

    Hi great review thank you!!.
    I am a long distance swimmer. it looks like you can’t get a signal if you wear it on your wrist – has to be in your cap – right?? Also how reliable is the heart rate monitor in the water – and how do I read it if it is in my cap?? I want to see my heart rate while i swim. Does any watch do this??
    Thanks so much, Fiona

    • The HR monitor won’t transmit through the water, as ANT+ only gets about 1-2″ in the water. If in the cap, it’s really only for tracking distance afterwards.

      For being able to have the watch on your wrist and getting distance, I’d look at the Garmin FR910XT, the Garmin Fenix2, or the Suunto Ambit 2/2S.

  346. Thanks for this review. I am after an alternative to Garmin. My last two have fogged up with condensation from sweat, messing up the electrics. Thanks to your pool test and the fact its designed for swimming it seems unlikely this will happen. Thanks for the most indepth product review I have ever read! I am getting one.

    I have a TGT for a long time and i have a lot of troubles with the USB cable charger; after a while stop´s for charging the watch and to connect to the PC. I ask for another cable to Timex and they sended another to me…but after a while starts all over again. Now i have to use a vise(yes…i have to do it slightly) to press the watch and the charger together.

    • Doug

      yes I hear ya! same problem, but for $10 bucks a new charger lasts about a year. I purchased 3! Still love watch. Will not switch until the battery goes dead! and even then, used TGT’s on ebay are less then $100

  348. Miguel

    I’m in a dilemma between purchasing the TGT or RT2.0, both from Timex.
    I’m mainly runner, but I do hope to return to triathlon later this year.
    What unit would you buy if you were in my position?
    In advance thank you very much.
    Kindest regards,

    • Doug

      Hi, I actually started with the run trainer 2.0 and recently switched to the TGT. The new firmware allows a foot pod accessory.

    • Doug

      Also, MapMyRun now accepts uploads from the TGT, which, if your not a fan of Training Peaks is a good alternative. Check out Amazon or Ebay. I just picked up the TGT for $60 with the HR monitor. People are jumping ship for new technology, but honestly this 4 year old watch still kicks butt, especially after all the firmware updates.

  349. Mark Lavita

    Hello DC Rainmaker, before hand a great thanks for your review…although i am aware it has been discontinued i just bought my timex global trainer recently (for $80) and your reviews are several light years more helpful than the actual instructions. So thank you very much and keep up the good work.
    I have however a question for you: One of the reasons i chose this watch was because, besides running i do a lot of open water swimming. To get data using the watch on my wrist is ridiculous so i put the watch in a pouch on my back. For some reason after a 1.500 – 2.000 m swim i usually get between 200-300 m extra (comparing the same path with google earth). Running however gives me a pretty accurate measure. I then realised that the extra distance swimming is because the GPS counts distance even stopped so the slower i move the bigger the error.
    I noticed than when completely stopped in 10 sec i would have moved about 4-6 m. Is this normal or is it a deffect of the watch or it has to do with some configuration or software configuration?
    I thank you in advance for your help.
    Best regards.

    • It’s normal when stopped to see slight variations with GPS – that’s because the accuracy of consumers units isn’t quite as great.

      If you were to leave a GPS unit outside in a garden, you’d find that by the end of the GPS track would look like a snowflake – totally normal.

    • Mark Lavita

      Hello, thank you for your fast reply. I still have, however the following questions:
      – A while back I was tracking in the woods (full day). I did several kilometers…but every time I sat for a rest (lunch/ dinner, other) i would continue increasing greatly the kilometers shown on my watch. For example a 1h rest would be equivalent to about 1,5 km…at the end of the day (after 13h) I must have walked about 10-12 km but actually had 23 km marked down which is ridiculous and makes this watch unusable for tracking/slow walking, etc. Do you agree?
      – Is there anyway to solve this problem? What do you mean by “consumers units”?
      – Does this problem also happen with other watches?
      Once more I thank you in advance for all your good and useful advice.
      Best regards,

    • Tom


      I had the exact same problem with theTimex Global Trainer – significant overreporting of distance while stationary. See my comments above.

      Rainmaker is correct that all units do this, however the TGT is MUCH worse than garmin units. I can’t remember exactly how much – I’ll do another test – but it’s in the order of 5 or 10 times worse from memory.

      My conclusion was that the garmin has much nicer software that handles the unavoidable GPS fluctuations in a more sophisticated manner.

      My solution was to go back to garmin!

    • Mark Lavita

      Thanks Tom,
      Went to see your past comments and realized this subject had already been mentioned here.In fact i confirm that for running it’s ok, but for open water swimming useless…and i bought this watch specifically for open water swimming since there are much cheaper gps watches only for running (non water resistant)..nevertheless i go through the trouble of using the watch in a pouch which i place on my back to end up having to use google earth to confirm my distance swimming… although in movement, at the end of a 1.500m swim (in about 30 min) i always get an extra 100-200 m…of course there could also be an error associated with the google earth measurement…but what’s the point of having a gps watch then?? in other words for swimming it’s probably best to just use a smartphone and put it inside my impermeable pouch and on my back to get an accurate distance…glad only paid $80+handling for my TGT…thanks all once more!!

    • Tom

      FYI, here are my recordings of stationary GPS performance:

      Timex Global Trainer: Recorded 7.7km in 10 hours, AVERAGE 0.77KM/H
      Garmin 310xt: Recorded 400m in 2 ½ hours, AVERAGE 0.16KM/H
      Garmin Dakota 20: Recorded 7 metres in 1 hour, AVERAGE 0.01KM/H
      IPHONE MotionX APP: Recorded 0 metres in 1 hour, AVERAGE 0.00 km/h
      I believe the iphone app uses the accelerometer to improve accuracy.

      The units were left stationary on my balcony on a clear day, with a good view of the sky.

      Timex Global Trainer is far and away the worst.

    • Interesting stuff. Though, I’d be cautious to draw too many conclusions from it – since almost all of these GPS devices were designed to track movement, rather than sitting still.

    • Tom

      The TGT is more innaccurate than the others when moving (e.g. your 2.5% reported error) and when stationary (e.g. my figures, and the other guys), so I’m comfortable concluding that the TGT isn’t as accurate.

    hi rainmaker, please help me choose;
    i would like to buy a gps sport watch under $250. what do you think i should have?
    i’m thinking of timex global trainer, timex run 2.0, nike+ sport watch gps, and garmin 310xt
    O, and by the way i’m a triathlete. So, what do you think?. Tks

    • Hi Alie-

      My full recommendations post is here: link to dcrainmaker.com

      it was just published a few hours ago and should cover the items you’re looking at. Cheers!

    • Mark Lavita

      Hi Alle i think the cheapest you could get is the Timex Global Trainer…but note that this watch has been discontinued (i think). On e-bay you could find a new one for about $100-120 (and some even include the heart rate band)..(i got mine for $80 + handling…used – open box but returned as new) but it has all the problems mentioned above (specially for swimming)…nevertheless a much lower price when compared to other models that apparently have similar problems…
      Good luck!!

  351. Mick Booker

    I have just bought a TGT but am totally confused. The watch is 45 minutes behind and the date 4 tears behind, it says it can’t locate a satellite, I think I’ve bought some junk!

  352. Mick Booker

    Thanks for responding so quickly but it is working ok now, it is just the position of my home, I only had to go down the road a little and it all sprang in to life, now all I have to do is figure out the rest of it lol.

  353. Humberto Rodrigues

    Hi, do you have the USB wall charger adapter – Timex Iroman Global GPS for to sell? It’s possible to send for Brazil? I can not find here… Tks

  354. Hey love the site and the reviews. Thanks for putting in the time. My main thing is the performance pacer. I am going to run a tri. I want to set it up with certain times for each part so I can know where I am at during it. Can it do this in one shot or do you need to set up different screens.

  355. john Z

    I really like your site. I have had the Timex Global GPS, for a few years now. Both ( Yes I had 2, got one really cheap), broke, one the button stopped working, the other, moisture got in…
    I sent them both back to Timex, as of thursday, they dont have any replacements for me, as they HAVE DISCONTINUED the Global GPS watch , this means that TImex Ironman, DOES NOT MAKE a multi sport watch.
    I am not looking at a new multi sport watch, may wait for the new Garmin or Suunto, thanks for your reviews, etc. Very very helpful. I wish Timex was still in the multi sport business. As I have used my Timex Global GPS for years, since it came out. Any way of contacting Timex and complaining, as the service folks , although extremely helpful and polite, can not sway company policy.

  356. Hrvoje

    Hello all…Hope somebody will have time and energy to help me out.
    I am going to run a tri. and in search for my first watch.
    I did read many of the posts in here but now I’m very confused..(I was sure that 150 $ ebay deal on TGT was excellent but reading all this stuff I’m not so sure) and I did go on the link
    link to dcrainmaker.com
    but still in doubt.
    first i was focused on FR310xt and then on Timex GT,maybe Timex Run Trainer? damn and the choices 😉
    DC, you’ve written “It hovers around $170-$190US” for 310xt..I didn’t saw that price range anywhere on Amazon and Timex seems to be a little cheaper.
    Anyway, I need an advice, my budget is max 200$, HRM, and a possibility to plug into a cadence sensor. If I figured iz out, no “watch” is perfect for open water
    Excellent job you are doing here DC. Very very helpful
    Many, many thanks DC, hope you’ll visit Croatia…
    and many thanks to all you folks here
    Thank you and bye

    Hi RM, as I use TimexIronman also on the plane to calculate the actual distance flown, do you know why it stops calculating the distance at 902 Km/ph? It shows only the actual speed and the coordinates. Do I need to change something or change product and which one? Thank you

  358. David

    Just a quick question. My 910XT is off at Garmin for replacement. In the mean time, I am using my wife’s old TGT. I paired it with my foot pod, and entered my calibration data from my 910XT, sort of (0.945 on 910XT, but the TGT only supports 3 digits 095%). But it seems to be indicating my speed a bit fast (low 9:xx/mile vs mid-high 9:xx/mile, and my distance a bit long (6.5 miles vs 6.2). Does it use the GPS or foot pod for speed/distance if both are available? I only really want the foot pod for cadence.

    Thanks for the great service you do to the endurance athlete community. Even on these old devices.

    • David

      Well, I changed the calibration factor to 092%, and the distance looked pretty spot on. So I believe it does use the foot pod for distance/speed instead of GPS if it is paired.

    This review was excellent. I have used this website to help me decide which unit to buy and the Timex GT is pretty hard to pass by. I run and also do triathlons and to find a watch that was waterproof, gave altitude readings and could switch sports was not possible for under $500, except for this watch. Thank you to rainmaker as I find these reviews very useful. Only gripe with this watch is the satellite reception as it takes forever.

      I consistently pick up a signal anywhere in about 1-min. Set it down until it picks up the signal. I do find that it takes several minutes to get a signal if it is on my wrist, so I stopped that a while ago. Just set it down so it’s still and it locks on quickly.

  361. Doug B.

    I just got a new desktop computer with Windows 8.1. I am unable to get a PC connection with Device Agent and the TGT after installing the drivers designated for Windows 8 on the Timex web page. I have also verified that I am downloading the 64-bit driver as specified for my system. I’ve been using the TGT for 2 seasons now and have had no problems until this Windows 8 hooey that I’m now experiencing. Have you heard of any problems with this? (I don’t know if it’s a Windows problem or a problem with the Timex drivers, but Timex customer service has responded to my inquiries to them but there directions have been no help.)

    • Doug B.

      Update: Next time I tried it, there was a positive connection with Device Agent (DA) and I was able to download workouts, change settings, the whole bit. It went well for a few weeks then one day it failed a connection again with DA. I decided to not fret and just try again another time. Sure enough, a day or two later the TGT and DA were talking again and haven’t had a problem in the following week now. I’m guessing that we TGT-ers with Windows 8.1 may just have the occasional day when these two just don’t talk to each other. It’s easy to blame Microsoft…so I will.

      As an aside, Timex stopped replying to my online pleas for help as I repeatedly asked about any issues they may be experiencing with the Windows 8.1 64-bit drivers. The last correspondence I had from them was to send in the TGT for repair. My response was that I would not because the TGT was still functioning perfectly well and uploading to DA on the Windows 7 computer at my work. REALLY frustrating and disappointed in the Timex customer no-service when it came to this inquiry.

    • Doug B.

      I just had the same problem with my Garmin Edge 500: both it and TGT uploaded fine on my work computer that uses Windiws 7, but on my home PC with Windows 8.1 Garmin Connect did not even recognize my Edge and Device Agent did not recognize the TGT. Got good results when I called Garmin cust svc. After explaining the issue in detail cust svc agent put me on hold & spoke with one of their IT guys or software engineers or something. Said it sounded like I was missing a windows update on my home PC. Sure enough, I ran a current Windows update and Garmin Connect now recognizes my Edge and Device Agent now communicates with my TGT. Hope this helps anyone who gets frustrated when DA doesn’t communicate. Bottom line lesson learned from this is to first run a Windows update.

    Hi there..
    Did you find a way of keeping the backlight on during the whole workout?
    I mean… When I go running at night
    . I have to keep pressing the backlight button all the time to watch my HR and pace?
