COROS Pace 2 In-Depth Review: A $199 Multisport watch with Running Power

DSC_8478

It’s been a while since there’s been a watch that could cause Garmin heartache, and the COROS Pace 2 is unquestionably it. No, it’s not a ‘Garmin Killer’, but it will easily siphon off sales. This multisport watch packs in a pile of new and existing features that cover the core needs of most runners and triathletes, while including features not found on even higher-end watches from most of its competitors – such as native running power without any required accessories. Or the lightest GPS watch in the world at 29g, or a new night workout mode. And for those more advanced runners, they’ve come out with easily the most comprehensive built-in support for the Stryd running pod.

Albeit, in doing so they also slyly made their own running power algorithms seemingly just about as good in 95% of scenarios. But don’t worry, I go through piles of data in painstaking data to illustrate that exact point.

And of course – all of this at a mere $199 – a fraction of the cost of a Garmin with similar capabilities in the multisport realm. But like all things potentially too good to be true, it’s not perfect here either. There are some quirks and other areas to be aware of. All of which I cover in-depth here in this review.

Note that COROS sent out a media loaner for me to test on. As usual, once I’m done with testing here I’ll get the COROS Pace 2 back to them and go out and purchase my own through normal retail channels.  No company gets to see any aspect of my posts or videos before they go live – that’s just the way I roll. If you found this review useful, feel free to hit up the links at the end of the post to help support the site.

With that, let’s begin!

What’s New:

DSC_7703_thumb

The COROS Pace 2 carries with it almost every feature found on the company’s higher-end watches, save a handful of features targeting the high mountains such as an SpO2 sensor (hardware), mountain climb mode, ski mode, and trail running mode. Though realistically, you can use running mode just fine for trail runs.

Still, the fact that a $199 watch has essentially all the same software as those higher-end watches is astonishing. And, before owners of those higher-end VERTIX, APEX, and APEX Pro units worry, yes, you’re getting all the same features of the new Pace 2 via software update (in fact, even the original Pace will get wrist power, but not the other features). COROS continues to follow the general model of Apple, Wahoo (and now Hammerhead) with keeping units on essentially the same software version as long as hardware allows for it.

Here’s what’s new in the Pace 2 specifically:

– Addition of running power without any accessory
– Addition of Stryd running power support with all metrics
– Expanded running power platform support (metrics/integration/etc…)
– Added running power targets to structured workouts
– Addition of training plans
– New night mode for workouts: Automatically enables backlight during workouts between sunrise and sunset
– Increased battery life from 25 hours to 30 hours of GPS on-time in regular mode
– Increased battery life from 50 hours to 60 hours in UltraMax mode
– Reduced standby battery from 30 days to 20 days (but with 24×7 mode with notifications/sleep tracking/HR tracking/etc…)
– Reduced weight from 48g (Pace 1) to 29g (Pace 2)
– Claimed lightest GPS watch in the world at 29g
– Processor capabilities increased by 1.5x
– Storage capacity increased from 16MB to 64MB
– New quick release bands (previous required tools)
– Reduced from 4 buttons to digital dial + button
– Watch size decreases from 46mm to 42mm, but screen size same at 1.2”

And then here’s some things that stayed the same:

– Still a full multisport watch with triathlon mode
– Still supports external sensors including ANT+ & Bluetooth Smart sensors
– Still has training plan, structured workouts
– Still has magnetic compass
– Still has barometric altimeter
– Water-resistance stays at 5ATM (50 meters)

Here’s a look at that new nylon strap – which is what I’ve been wearing with it. I quite like it:

DSC_8463_thumb1 DSC_8464_thumb1

The only downside to the fabric strap is that for about 30 minutes after a shower (or a swim), it retains water and transfers it to your clothes if you lay your wrist on yourself (such as sitting on a couch flipping through your phone). The Whoop fabric strap has this same problem, though seems to retain slightly less water (and thus transfers less water to your clothes). It’s not a huge deal…unless you follow every shower with sitting on the couch with your hands in your lap on your phone.

In any case, you’ll notice the digital dial in there, which replaces some of the dedicated buttons. Digital dials honestly aren’t my favorite thing for sports watches, and that’s true here as well. I find them super finicky for changing data pages mid-run (and near-impossible while riding), and that carries through to the Pace 2 also. I’ll miss the dedicated buttons of the original Pace.

Finally, there’s two colors (white or dark navy) available at launch – with either the nylon or silicone band:

image_thumb44

Ok, with that out of the way, let’s backtrack slightly to the unboxing section.

Unboxing:

There isn’t anything fancy about the COROS Pace 2 box, and honestly, there really needn’t be either. It’s clean and simplistic.

DSC_7703 DSC_7707

Inside you’ll find the watch encased in packing support, looking up at you – ready to…umm…#exploreperfection, I guess.

DSC_7709

Rip all the stuff out of the box, and explore my perfectionist capability to place it in a nice tidy pile so you can see it:

DSC_7714

Here’s the watch, complete with the new fabric strap.

DSC_7718

And a closer look at that fabric strap:

DSC_7722

You’ll then find two little plugs for the charging port. These ostensibly can keep out sweat and other gunk long term, but realistically, I’d argue that if you need these plugs – you’re probably doing it wrong (namely, you should consider taking a shower). I’ve never heard of this being a problem on Fitbit/Garmin/others that have the same charging port design. I’ve already lost these plugs.

DSC_7725

Speaking of plugs, here’s the thing you plug in – the charging cable:

DSC_7737

And then finally, the manual:

DSC_7738

With that – let’s get cooking on using it.

The Basics:

DSC_8739

For this section here I’m going to focus on some of the basic non-sports features – things like activity and sleep tracking, as well as other tidbits on the watch itself (features and exterior elements). If you’re looking for the sport-specific bits, then skip ahead to those sections.

The watch has 2.5 buttons. It’s got a lower right button that simply goes in and out. While also having the upper right digital crown, which is both a dial that rotates as well as a button that presses in/out. You’ll use the dial to go up/down through menus (and pages), as well as to act as a confirmation button by pressing in for menus.

DSC_8658

The screen is not a touch-screen display, but is color. Unlike the original Pace which had 5 buttons, there are no other buttons. While some people like the digital crown, I’ve long noted that for sport reasons I find it fiddly, especially mid-workout. It’s honestly about the only piece of the watch I dislike. COROS uses it on their higher-end watch, as does Apple of course too. But that doesn’t mean it’s the right decision for a sport watch. In the case of Apple, the digital crown has far more utility in apps/etc than it does on the app-less COROS units. This seems like a case of form of function. But again (and not to spoil this entire review), it’s really the only thing I don’t like on this unit.

DSC_8740

Now, if we use that digital crown and rotate it we’ll advance through the widget roll. This includes your daily metrics like calories, steps, stairs, etc…, then graphed metrics for the last 6 hours. These include your heart rate, the altitude, the barometric pressure, the temperature, and sunrise/sunset information. Finally, you’ll also see smartphone notifications. Here’s a gallery of those.

You can also tap in and use the digital crown to move forwards/backwards through data points there (including beyond the 6-hour window), which is kinda neat. You can see here from the middle of my workout a few hours back:

DSC_8669

The default watch face itself (which is changeable via the app between a pile of watch faces) shows most of your stats for the day, including steps, total workout time, heart rate, time, etc…

DSC_8668

If you press the lower right button it’ll iterate the tiny top text metric through data like sunrise, sunset, battery, and stairs climbed.

If we long-hold the lower right button we get into a mini-controls menu. This includes a super-detailed battery information menu, the ability to broadcast your heart rate, compass, UltraMax enablement (though you actually enable this elsewhere), satellite signal, stopwatch, timer, alarms, night mode, watch face, and settings.

DSC_8670

The battery panel is worth serious props. It’s super detailed in what’s driving battery change on the unit itself. Very similar to what you’d find on a phone in the advanced battery diags to see what apps or features are burning the most battery. It’s interesting to contrast the battery details that COROS has vs what Garmin/Suunto have. In the case of those two companies, they’ve invested heavily in allowing you to (with significant granularity) specify what features are enabled/disabled and impacting battery. But they don’t allow you to look back historically at what’s burning battery day to day. Inversely, COROS doesn’t have the same level of granularity as Garmin/Suunto in terms of enabling/disabling various features to control battery rate.

Meanwhile, down in the settings menu, you’ll find all sorts of the usual settings like changing how the data is displayed to pairing sensors and your phone. Don’t worry, we’ll talk about sensors a bit later on.

DSC_8690 DSC_8689

Now back at the main watch face, as if you were just wearing the watch, you can tap the right button to open up the sport menu. This allows you to choose which sport you want, as well as some of the non-sport starting menu pieces like history, settings, and AI Trainer. Certainly these are tied to sports in various ways, but don’t start an active sport.

DSC_8692

Again, we’ll get back to all this sports goodness later. Now the COROS Pace doesn’t have features like music, NFC payments, or 3rd party apps. As such, we’ve covered all the non-sport features on the watch at this point

So let’s switch over to the smartphone app to finish up the basics section. As we crack open the COROS app, the main home screen shows the core activity stats for the day. You can swipe left/right to go back/forward to previous/other days. At the bottom any workouts you’ve done will be displayed, as well as summary stats including those stats related to training load and fitness levels:

2020-09-03 16.47.35 2020-09-03 16.47.42 2020-09-03 16.47.45

You can tap on a given stat to see more depth on it, for example this sleep page here – both at the given night level, as well as at the week/month/year levels:

2020-09-03 09.42.45 2020-09-03 09.43.40

In terms of accuracy of the sleep data, I’ve found the start/end times accurate, but its detection of whether or not I’m awake seems pretty skewed and often incorrect. In my case it doesn’t help that we’ve got three little ones at home in their first few weeks in a new home, so there’s been all sorts of wonky wakeups. But, I haven’t seen other watches being as challenged by that.

The same graphing ability is also there for 24×7 heart rate (as well as steps, active energy/calories, and exercise time):

2020-09-03 09.44.25 2020-09-03 09.44.09

Note that resting heart rate is pulled out into a different section shown at the monthly/yearly level, and lacks some of the granularity that most companies provide. I’d love to see that allow you to go down to the weekly/daily summary level as well. Also note that with the COROS Pace 2 you can specify whether you want ‘Realtime’ 24×7 HR, or ‘Every 10 minute’ HR.  I mostly just kept it on the 10-minute option, since the granularity of the charts is lesser, I wasn’t as fussed then on the granularity of the underlying data.

The next tab over is your workouts, showing you a list of recent workouts, and you can tap on any given workout to see more detailed stats (more in the sports section):

2020-09-03 16.49.57 2020-09-03 09.33.33

After that, there’s the profile tab, which includes the usual configuration stats like gender/weight/age, as well as the ability to link up 3rd party apps here. They’ve got most of the major ones you’d expect, though I’d love to see this expand a bit to include apps like Dropbox for example (similar to what Wahoo does).

2020-09-03 09.34.09 2020-09-03 09.34.37

Then finally there’s the watch settings page. This shows paired watches to your account, and lets you dig into customize everything from data pages to watch faces to which notifications appear. Most of these settings are pretty normal, however interestingly they do allow you more granularity over notification apps than most companies. So while some companies leverage the default iOS/Android notifications control center, this goes a step further and lets you choose which messaging apps can interrupt your life:

2020-09-03 09.40.56 2020-09-03 09.41.36 2020-09-03 09.40.57

Ok, with that, we’ve covered pretty much all there is to cover here. Let’s dive a bit deeper on the sporting side.

Sport Usage:

2020-09-01 13.18.10

The COROS Pace 2 has all the core functionality you’d need from a running or triathlon watch. Plenty of data fields to choose from, and wide accessory support for ANT+ & Bluetooth Smart accessories. I’ve been using it with cycling power meters for example, without issue.

In fact, that’s really what separates something like the COROS units from a Garmin or Suunto – the extra sports (and non-sports) features you may or may not use. For example, on the COROS Pace 2 you won’t find something like ClimbPro (monitors/shows climbs on a course mid-workout) or PacePro (race course pacing that accounts for elevation pace shifts, etc). And there’s probably 50 other features the COROS Pace 2 doesn’t have that Garmin does. But ya know what? That also OK.

For example, right now I have zero races on my calendar – so PacePro isn’t of significant use. And I live in a pancake-flat area, so ClimbPro isn’t of use (though I absolutely love it when I can escape to the mountains). As with everything, it’s a balance of deciding what features are valuable to you. Let me show you what is there today, and then you can decide yourself.

With that, let’s start a workout. To do so tap the top right button, which cracks open the sport menu. It’s here you can choose which sport you’re doing. They have all the core ones like Cycling (indoors and out), Running (indoors, outdoors, and outside track), and pool/openwater swims. Plus triathlon and strength training. There’s also some catch-all options like Gym Cardio and GPS Cardio. But you won’t find sport-specific options for things like stand-up paddleboard or skiing.

DSC_8743

We’ll choose run here. In my case I’ve got a training plan enabled on my unit, so it then offers me to load that scheduled workout up. There is a minor spelling/grammatical error here (should be ‘Start’ not ‘Star’), which is kinda part of the occasional lack of UI polish that I see in the ecosystem (mostly on the app side, but occasionally in the watch):

DSC_8744

Once that’s done you’ll see GPS, heart rate, and battery status along the bottom. Once the heart icon and GPS icon stay lit green you’re good to go.

DSC_8745

If you try and pre-maturely go, it’ll warn you that you’ll probably eff up your workout and thus deserve the ridicule you’ll get on Strava afterwards. I mean…it says it in prettier words, but that’s what it means.

DSC_8746

You can also tweak a couple of minor settings, including some alerts (Distance/Pace/Cadence/Heart Rate/Nutrition), enable/disable Auto Pause, and turn on/off the metronome.

DSC_8745

There’s also a simple interval option here to configure intervals with a pre-defined repeat/rest definition, and then a warm-up/cool-down. It’s basic, but in line with their competitors. Like their competitors, if you’re looking for more advanced workouts you’ll want to use the workout builder (which I detail later in this post).

DSC_8749

With all that ready to roll you’ll go ahead and press the start button and it’ll start tracking your run (or any other workout type). You’ll see your data pages as you’ve configured them on the screen, and it’ll be recording in the background on the watch. There’s no Live Tracking type service within the COROS platform, so everything is local to the watch.

2020-09-01 13.13.29

You can iterate through the data pages by using the digital crown, rotating it up or down. While this ranges from so-so to finicky on a normal day, it’s a pain in the butt with gloves. COROS has shifted to this design from the previous all-button design.

2020-09-01 13.13.46

That upper right button acts as a start/stop button too, and then the lower right button is your dedicated lap function. There’s also auto-lap too if you want, but I’m more of a manual lapper.

Once you’re done with your workout you’ll hold the upper right button after pausing to finish the workout and save it.

2020-09-01 13.17.45

You’ll get a slew of pretty graphical summary screens here. This is an area that gives more detail and prettiness than Garmin does, though is in line with Suunto:

There’s also the recovery scores seen above, as well as the Stamina feature, which gives you basically a Streetfighter like score of how recovered you are to give it a go again. I haven’t found this terribly accurate, though, I have found the hours listed below it a far better representation of recovery time than the %-based metrics on the upper line:

DSC_8763

Afterwards, all of your workouts will sync via the COROS app, and you can dig into all the metrics there in far more detail. Here’s a pile of those:

Note that there is no COROS web platform/dashboard. Instead, the workouts will automatically sync to whichever 3rd party connected platforms you’ve paired up. In my case that was Strava and TrainingPeaks. You can see a workout here on Strava – this one from one of my runs:

image

Switching over to aquatic activities, I had no issues swimming with it either (openwater). I simply selected an openwater swim, waited a few seconds for GPS, and then was ready to roll:

2020-08-28 15.30.33

While swimming in openwater it’ll use a slightly different algorithm to account for the watch being below the water the entire time. This smooths out the track a bit (on purpose) so that it can also deal the lack of GPS signal underwater. The updates to distance and pace though are pretty constant the entire time, and were within a couple meters (live) of other watches I was using on the other wrist at the same time over various swims.

2020-08-28 16.07.02-1

I look at the GPS tracks a bit later on, but in essence they were good, albeit not quite as perfect as the current openwater swim track king (Garmin Swim 2). But realistically you’d never notice the difference in that nuance unless you had a slate of side by side tracks to compare against.

2020-08-28 16.15.39

Now, before we talk about running power I wanted to briefly mention track mode – namely because it’s awesome. Track mode came out back last November, and essentially does two things: Snaps your GPS track to the shape of the track (and a specific lane), and then snaps your distances to round numbers like 800m, etc… – knowing you likely pressed the button as you crossed the line.

To begin track mode you’ll select that as a sport, and then validate the lane you’re primarily running is selected:

2020-08-26 16.03.52 2020-08-26 16.03.56

Once that’s done, you simply run. It’s that easy. It generally takes about two laps before the track is recognized, and it’ll actually give you a notification that the ‘Track is recognized’. Though, I had a hard time getting a photo of that quick notification.

By default it has a 1,000m auto-lap enabled, which I always forget to disable so that triggers during my 1600m warm-up. But after that point most of my sets recently have been 800’s, so it doesn’t much matter since I’m manual lapping them. Thus as I cross the line it ‘snaps’ the distance to 800m, and does all the pacing based on that. You can see this most easily in the lap summary page, which is accessible anytime during the run by pausing.

2020-08-26 16.04.07

You can also change the lane too, though realistically you’d only do that if you were permanently ‘moving’ to that lane, else it’s kinda finicky to do mid-workout since you have to pause to do that as well.

Still, the proof is (mostly) in the pudding, which comes afterwards. Sure, you’ll first see that beautiful track photo on your workout summary screen:

2020-08-26 16.51.41-1

But then once you upload you’ll see the GPS line on the track is nice and super crispy:

2020-09-03 17.03.19 2020-09-03 17.03.24

However, as you see above – it’s not perfect. It seems to have incorrectly determined the shape of this track, and so it made my track a bit more ‘skinny’ than it really is, resulting in the curves being out in the bushes, while the straightaways are in the field a bit. But hey, nobody on Strava will probably notice that, they’re just looking at the pretty circle. Plus, the 400m distance remains accurate, even if the shape isn’t.

Also, you will notice that all of the lap splits, save one or two, snapped to the correct 800m or 200m work/rest cycle I was doing (plus the warm-up chunks that got auto-lap split at 1KM).

2020-09-03 17.03.35

Anyway, it’s super impressive – and hopefully we’ll continue to see them work away at it, tweaking the minor bits like the track recognition.

Note that there is the ability to enable UltraMax, which considerably saves battery life by reducing the GPS-on/recording time to 30 seconds out of every 2 minutes. It’ll still capture pace/distance/etc while running/hiking using the accelerometer. It’s a little funky to enable, as you’ll first go into Run, then from there you’ll long-hold the lower left button, and then toggle this UltraMax setting:

DSC_8764

Because the battery life is already so good on the Pace 2, I haven’t had any reason to enable this. In general, I never recommend folks use UltraMax/UltraTrac/Ultra-whatever from any brand unless they explicitly know they’re going to go beyond about 80% of the claimed battery life of any watch. Otherwise you’re simply sacrificing data accuracy/GPS tracks for the fun of it.

Finally, for lack of anywhere else to note it – you can pair piles of ANT+ & Bluetooth Smart sensors to the COROS Pace 2, including multiple of the same type (such as for multiple bikes). I’ve used it with a Quarq DZero, Favero Assioma Pedals, and PowerTap P2 pedals successfully:

DSC_8766 DSC_8767 DSC_8765

Inversely, the unit also broadcasts your heart rate over ANT+. Here you can see that using the Broadcast HR mode, on a Peloton bike:

DSC_8686

I haven’t used this feature though in any depth, so I can’t speak to the nuances as much there.

Ok, phew – with all things covered, let’s dive even deeper into the running power side of things.

Running Power:

DSC_8470_thumb

While COROS has implemented running power natively into the COROS Pace 2 (akin to what Polar did with the Polar Vantage), they’ve also dramatically stepped up their running power support in general, via an increased partnership with Stryd. As part of that, they now support every Stryd running metric when paired with a Stryd pod – from Form Power to Air Power, plus all the running efficiency ones like Ground Contact, L/R Balance, and more. In addition, the COROS Pod gains all but one of these metrics as well.

But if you’re looking for the main metric of running power, that doesn’t require any pod at all – either COROS Pod or Stryd. You can just use the watch on your wrist like a normal human and it’ll give you total power as well as smoothed variants of that (based on the data fields you choose). And you can create structured workouts based on those power targets too.

Now, we’ll circle back to the nuances of wrist-only vs Stryd footpod vs COROS Pod in a moment. Until then, let’s look at the running power bits on an actual run. To do so, you’ll want to ensure you’ve got the running power data fields configured/enabled on your watch, via the smartphone app. In my case, I configured them similar to how I do my cycling power, with different smoothed variants:

2020-08-25-16.45.15_thumb2 2020-08-25-16.45.20_thumb2

Randomly of note, COROS is removing the ‘Running Efficiency’ metric and original running power analysis from their app. The other metrics will remain the same (while it adds the new FORM Power metric when paired with either COROS or Stryd pods).

Also – if you’re pairing up a Stryd pod, then you’ll get to add all the Stryd data fields too, like Air Power. And if using a COROS Pod, then you’ll get fields like Vertical Oscillation you can add.

And at that point, you’re basically ready to run. So go ahead and choose to start a run and wait for satellite and heart rate lock. Both typically only took a few seconds.

DSC_8472_thumb

Now, start running. You’ll see your running power displayed per your configurations, such as below from my run last night:

2020-08-24-20.44.19_thumb

In my case though, for my recent runs I’ve upped the ante and brought out various comparisons, specifically the following setup:

– Left wrist: COROS Pace 2 with native wrist power
– Right wrist: Polar Grit X with native wrist power
– Foot: Stryd Air footpod for running power
– Chest Strap & Running Shorts: Garmin HRM-TRI & RD-POD for running power

So in essence, I’ve tracked all four across numerous runs to see how they track. And it’s fascinating. The Stryd and COROS Pace 2 units tracked near identically. Some minor differences here and there, but run after run the values shown on the displays were almost scary close.

And after the fact, the data supports that as well. Here’s those four plotted from last night’s run, which was steady-state for the first 5KM, and then 800m intervals for the next 5KM. The COROS and Stryd are lower down in purple/brown:

image_thumb1

Now, as I’ve pointed out countless times before with running power data – this does not mean COROS & Stryd are right. It just means they agree. As with numerous other running power products on the market, this is not standard for how to measure running power. It might sound like a silly thing, but there really isn’t any agreement there from scientists, let alone companies. At this point, it’s mostly more about consistency within a given unit than anything else.

Garmin, Polar, RunScribe, and others tend to take a different approach to the data than Stryd (and now COROS). Usually it’s noted that if you add the Stryd Form power value to the Stryd power value you get into the same ballpark as Garmin/Polar (though even that is variable). You can see this below by looking at the lowest line that hovers around 100w (Stryd Form Power):

image_thumb3

In any event, if we look at another run I did (which includes going up/down some hills), you’ll see the COROS & Stryd are again nearly identical, with the COROS data smoothed a bit more. And in fact, I generally found the COROS power data a bit slower to respond than the other units, and you can see that both above and below near some of my surges.

image_thumb51

Note that for the image directly above here, I did have Garmin’s running power enabled, but forgot to put a new battery in my RD Pod, so it dropped out constantly until it died. Whereas on my earlier run I used the HRM-TRI.

Finally, I’ve just added in another run – this one on a crazy windy day. Winds were sustained at 30KPH, and gusting to 50KPH. I did this on a track, which is fun for a lot of reasons. First, because the wind was consistently either head-on or tailwind (aligned to the straightaways, making it easy to spot). Second, I was doing 800’s, and as you can see, my pacing is rock-on consistent. Variations in power were largely due to gusts (and probably a bit of running form change over time due to the wet surface). Note, the COROS Pace 2 was in track mode (so, still using GPS, but ‘locks’ to the track shape). The workout was primarily 800’s, with 200’s easy in between. Then some 200 sprints at the end.

First, here’s all four power sources at once (Stryd Air Power, COROS Pace 2 wrist-based power, Polar Grit X power, Garmin Power via HRM-TRI), data set here:

image_thumb31

Pretty similar to what we’ve seen before. Let’s go ahead and remove the Garmin/Polar ones, since people most want to see/understand the implication of the wind, and Stryd’s Air Power accounting for that.

Looking at the first 1600m, there’s virtually no difference whatsoever. That’s the warm-up session (I did a warm-up from office to track as well, so this was the on-track warm-up). Remember, each time I looped the track I’d encounter the strong headwind and the strong tailwind, plus the crosswinds at both ends.

image_thumb5

These were roughly done at ~6:05/mile (about ~3:45/KM). Nothing crazy, was more focused on keeping them super consistent. And you can see from the speeds, they were. Here’s the Stryd Power Center data from the pod showing the blue line of how stable I was:

image_thumb71

And here’s the data from the Garmin Fenix 6 showing the same stability using the GPS/wrist-based hybrid for pace (despite claims to the contrary, all major vendors use a blend of GPS + wrist-based accelerometers for smoothing pace data).

image_thumb9

Again, wind-speed measured a few blocks away at the weather station was ~30KPH sustained, with gusts to 57KPH (I started at ~4PM).

image_thumb1[1]

So let’s look at the 800’s more closely from a power standpoint. I’d start a jog about 10-12 seconds prior to each one, arriving at the line and hitting lap at that point on-pace. Since I was jog/walking 200’s in between, it meant that I was alternating whether I’d hit a headwind or a tailwind first for each set.

image_thumb11

And what do we see above? Relative consistency, but no specific repeatable differences between them. For example, they both trend relatively similar, but also have unique differences. But those differences don’t actually appear related to the wind. Here, let me show you. Below is from Stryd Power Center. On the map to the right I’ve illustrated the wind direction with the red arrows, and then my running direction around the track with the blue arrows. The little white splotches in the corner are where I started each set of 800m. So I’d always start on a corner, and then either hit headwind or tailwind.

image_thumb15

Now, let me add in the grey shading of Air Power to the Stryd chart:

image_thumb17

It’s hard to see, but it’s the grey under the orange bits. Here’s the 2nd interval zoomed in on, as we’ll use that for comparison:

image_thumb20

So let’s look at the comparison of just that interval, since there’s both similarities and differences there. Note the above/below charts don’t precisely match sizing. Also, my annotations aren’t perfect to the second because I’m trying to match things up on the map on the track – but they illustrate the gist of it pretty well.

You see that the Stryd seems to spike slightly higher as I start the interval – logical since as I’ve shown above, the COROS Pace 2 seems slightly more smoothed. Like most people, the first couple seconds I tend to start a touch bit fast and then settle in by 5-8 seconds in. As I hit the first tailwind, both units decrease correctly. And then, as I hit the first strong headwind, both units rise correctly together. So despite a Stryd Air Power factor showing 8% for this 100m section, COROS Pace 2 power matches the power perfectly. In other words, having a wind sensor made no difference there.

image_thumb21

Then we hit the section labeled ‘Side’ above. In this case the two units disagreed. This end of the track is a spot that’s semi-protected by a small line of trees/fencing. Stryd believes the wind here was strong at 5-7%. I’m guessing it’s misreading that. It was raining outside, and perhaps the sensor hole got some droplets in there. I’m not sure, but I am sure there’s no headwind there (as it correctly showed on most other laps). Also, given I was just coming off the headwind, it’s unlikely I double-down on power again. If you scroll up to the Garmin/Polar power, neither show the Stryd spike there.

Anyways, onto tailwind section #2, and both are the same. And then into headwind section #2, both rise up, with the COROS actually rising higher a little bit (Stryd reported a wind factor of 8% again for that portion).  Following which you see the Stryd power cut-out quicker than COROS, which takes a few more seconds after I stop to cut-out (again, the smoothing I discussed earlier).

This cycle repeats essentially the same for all of these sets. The exact variations differ, but it seems pretty darn clear there’s no meaningful difference in these from an on the run pacing standpoint. Like most running power products, they both are somewhat variable in the actual values second to second.

So what about the 200m sprints? Ask and you shall receive. In this case, I started all of them in the same spot – which was with a sidewind followed by a tailwind. Then 200 easy in between. You can see some moderate variance, namely after the first interval.

image_thumb23

You see the slight bit of delay on the COROS Pace 2 power values for Interval #1, though Intervals #2/3 are only about a second behind. Interval #4 (which I ran the fastest of them across the entire interval) was virtually identical in responsiveness. Meaning, COROS appears to smooth less when the change is more sprint-like (whereas an easy roll into an interval means it smooths more).

On intervals #2/3 Stryd spikes quite high above COROS towards the first 1/3rd of each interval. I was curious if Garmin/Polar also did this, and they do to an extent – Garmin more so than Polar (relative to the baseline for the rest of the interval). I’m not really sure what to make of that. And honestly, I’m also not really sure who (if anyone) is using power to pace 200m intervals, as realistically time/pace is a better indicator there given the variability of power over such a short timeframe.

image_thumb25

Ultimately, what my windy day at the track showed me is that there was no obvious (or even non-obvious) benefit to an air pressure sensor over what COROS has come up with. In the handful of times they differed (such as on one of the curves) – I don’t think the Stryd was correct there anyway. And then inversely, in the case of the 200m sprints, I don’t think the air pressure sensor specifically was a notable factor, rather, the fact that algorithms are accounting for accelerations differently.

But wait – there’s more. What about a trail run? A few days ago on a non-windy day I took to the trails to see how it might handle different terrain surfaces. This is an area that’s always been a bit challenging for Stryd. Specifically the softness of the trails, where Stryd (as well as other running power meters) don’t accurately handle when you go from hard surfaces (concrete, hard pack gravel), to soft surfaces (like sand, mud, or mushy stuff). So after getting into the forest, I did my best to find all the surfaces. Hard pack, softer pack, horse trails that sunk in like beaches, and so on.

2020-09-01 12.40.16

And what I found was that this was by far the least similar data set between Stryd and the COROS Pace 2. Sure, they trended in the same directions, but the offset was greater. Here’s that data:

image

I mean yes, they look similar at a high level, but have a greater disparity between them across the board. Also, every 10 minutes I did a sprint of sorts at increasing durations. You can see the first one at 30-seconds long shows the lag from the COROS Pace 2 power in comparison to Stryd, but it also shows it lower too. The next one at ~21 minutes shows the lag, but the COROS power gets higher. And finally at the 30-minute marker you see 3xSprints where the COROS actually doesn’t have as serious lag. This is a pattern I’ve seen throughout all my runs, whereby for more gradual pace increases to a higher intensity, the COROS lags. Whereas for true sprints it picks it up almost immediately.  I suspect this is something they’ll be able to solve fairly easily with some algorithm smoothing tweaks.

Finally, some of you have asked about indoor running with COROS wrist-based power. During COROS’s product announcement presentation they noted that indoor power doesn’t work. Except, in my testing it does seem to. Now I haven’t done an exhaustive treadmill comparison here. Instead, I was more interested in the general construct of whether or not it worked at all, and if it was in the ballpark. So, I jumped on the treadmill and opened up the indoor running mode and gave things a whirl:

DSC_8771

Huh. Nothing burger. No data was displayed in the power metrics while running on the treadmill:

DSC_8772

So, then I tried something fun – I changed it to the outdoor running profile. The same profile I’ve been using since July for my runs. Sure, it wanted GPS, but I was under a 6 or so story giant concrete building. It wasn’t gonna find GPS no matter how much it might want to. I ignored the GPS warnings and press start. Sure enough, running power (and I did this with another pair of shoes that had no pods, no HR straps on me, just me and a t-shirt/shorts):

DSC_8773

Now I haven’t yet had a chance to do a full sweeping comparison indoors between this and Stryd. However, I can say that the power values I was getting were in line with the same Pace 2 power values outside. And they were pretty darn steady (crazy steady actually). Maybe more testing to come there.

Now, for comparison on the technologies, COROS put together a pretty detailed chart comparing the different options. I then layered in a few more line items, and added the Polar units to it as well.  I will point out I appreciate that over the years COROS is always astonishingly accurate in their competitor comparison charts, they don’t tend to be heavily skewed towards them (nor omitting competitors’ features). In other words, I rarely have to take out the red marker and make corrections to it.

image_thumb11[1]

Ultimately at this point I’d have a really hard time with digesting why I’d need/want another pod. Sure, there’s more metrics to be found – but I feel like with as many years down the road we are on the running power journey, there *still* isn’t clear guidance for using those other metrics to train or race faster. At least from a purely metric-driven standpoint.

Stryd has other aspects of their platform that would drive adoption, like their race power calculator platform and sync process, which allows you to put in the course for your race and it basically spits out a running-power driven race plan. That’s cool.

Or their entire Stryd Power Center dashboard, which allows you to do more detailed analysis of your runs from a running power standpoint.

image_thumb7

But realistically, most people are going to stay watch-based when it comes to power. Meaning, they probably aren’t going back to the Stryd dashboard every day, aside from casual looks. It is notable that upon launch you’ll be able to pair a COROS & Stryd account together on the back-end.

In fact, as I got to this point in the post I started to wonder if COROS bought a financial interest in Stryd, or acquired them. Because frankly there’s no logical reason why Stryd would agree to all this, as at this point there’s very little reason for most people to buy a $219USD Stryd sensor if you’ve got a COROS watch.

So…I asked.

And COROS says that they do not have any financial interest/stake in Stryd. Further, they said that all of the wrist-based running power work they did was entirely by themselves, as Stryd wasn’t even aware of the wrist-based running power coming to COROS units until the day of the dry run broadcast presentation with COROS.  COROS says that the two companies are both smaller, and the synergies of ensuring both products worked well together was the main driver for increased Stryd integration.

Speaking of that integration, if you do decide to add a Stryd pod, you’ll find some handy features. First off though, add it through the ANT+ sensors menu like normal, except you’ll see Stryd listed once it finds it:

DSC_8488_thumb1 DSC_8489_thumb1

The first thing it’ll ask after you select it is for your critical power, which you can find via Stryd’s app/site:

DSC_8490_thumb1 DSC_8491_thumb1

By having this data, you’ll get correct Stryd power zones natively on the COROS watch – which is a huge deal in terms of how it compares to other competitors. While you can download the Stryd Zones app for a Garmin device via Garmin Connect IQ, this just does it natively.

Next, there are also two additional settings. The first is the ability to change the distance setting to toggle between Stryd and GPS:

DSC_8492_thumb1 DSC_8493_thumb1

And then the second is the calibration factor, which you can adjust as well:

DSC_8494_thumb

Again, these just re-enforce that if you have a COROS watch and Stryd, you’ve got a pretty powerful setup.

However, the flip side is that for most people, unless you really really really want Leg Spring Stiffness and Air Power (which, you probably don’t), or some of the Stryd platform bits – I think there’s very little value to picking up a Stryd sensor for use with a COROS watch. Especially given how impressively close the two values are.

And again, remember, all this running power goodness comes to all existing COROS watches, so if you’ve got a Stryd already (or if you’ve got nothing) – then you’re in luck!

Training Plans:

DSC_8478_thumb

Aside from running power, the other major new feature on the COROS Pace 2 (and again, to other COROS devices now too) is the Training Plan/Calendar feature. This allows you to not only create training plans, but also share them too – even with something as simple as a QR code.

To begin, you’ll go into the settings of your watch and select training plan. As with the structured/gym workout functionality, this particular placement is a bit wonky because it *requires* you be in range of your watch and your watch be powered on (and Bluetooth happy with your phone). This means its not something a non-COROS user can do.

In any case, hit ‘Add Plan’, followed by ‘Create Plan’. Note though that if someone sent you the URL for the plan (or QR code or pigeon messenger or whatever), then you can simply tap that instead to open up their plan. More on that in a second.

2020-08-25-16.55.08_thumb2 2020-08-25-16.55.04_thumb2

Once you’ve got a plan created you can add either previously created structured workouts (such as step by step targets, like I showed in the running power section) for running, cycling, swimming, and weightlifting/core/gym. I showed the power of the gym workouts previously here. You can essentially add one of those complex step-by-step workouts, or, you can add a simplistic workout, such as below with a target of 50KM for the ride and a given intensity level. Same goes for a run.

2020-08-25-16.55.11_thumb2 2020-08-25-16.55.41_thumb2

Whereas if you choose from your workout library, then you get far more detailed step by step options.

2020-08-25-16.55.46_thumb2 2020-08-25-16.55.54_thumb2

This is all in the pursuit of adding workouts to a week by week baseline, but not necessarily a given date. See, with the training plan the goal is about making this distributable, rather than personal to you. So you’re aligning things to days of the week and week #’s, but the exact start date will vary based on what you choose later.

Also, now is later. Once you’ve added a pile of workouts to your plan you can go ahead and save it, and then set the start date. After which, you’ll sync it to the watch:

2020-08-25-16.58.45_thumb2 2020-08-25-16.58.50_thumb2

Once on the watch you’ll go to start a new sport, but instead choose the Training Plan menu:

DSC_8479_thumb

Then the date, and then the planned workout:

DSC_8480_thumb1 DSC_8481_thumb1

After that, it’s just like before with structured workouts:

DSC_8483_thumb

While some companies do allow multiple training programs to run concurrently, COROS does not, only one at a time (frankly, it never ends up well doing multiple anyway). So you can remove a plan if you want, via the app.

That in turn allows you to add in other plans from someone else by just scanning the QR code, or, if they e-mailed you the plan URL, that’ll work too.  For example, you can see below me loading up someone else’s plan, and then adding it to my calendar:

2020-08-25-17.11.02_thumb2 2020-08-25-17.11.04_thumb2 2020-08-25-17.11.07_thumb2

All of this works pretty well, though is occasionally a bit clunky – primarily due to the modal nature of requiring not just your watch, but your watch not be in any active menus (and also be connected). Essentially the same quirks I saw this past spring where a bit more polish would help here. Also, it doesn’t import/account for plans from TrainingPeaks or other sources, so that makes it less appealing for now.

Still – I really like the changeability aspect of it, that’s something that’s fairly hard to do with your own plans and friends. Or just creating a simplistic plan for a family friend.

GPS & Heart Rate Accuracy:

DSC_8467_thumb

I’ve got runs and rides stretching back into July on the COROS Pace 2, and overall, it’s pretty impressive. Not perfect mind you, but pretty good. In this section I’ll take a look at both the heart rate and GPS accuracy compared to other units on the same workout.

So let’s dive right into it, starting with last night’s run (and then working backward from there). This run was a simplistic 10KM, but split into two pieces. The first part I was feeling lazy, so just ran nice and steady Z2. But then the second part I was feeling frisky and did 800m interval repeats. Starting with the GPS track, here’s what that looked like on this out and back route. Oh, and this is compared against a Polar Grit X, iPhone 11 Pro, and Garmin Fenix 6 Pro. Basically, all higher-end units.

image_thumb46

So at a high level, it’s hard to tell. You can see some purple spots peeking out from the Garmin Fenix 6, but the others look pretty close. So let’s zoom in a bunch. Here you can clearly see that the Garmin Fenix 6 struggles quite a bit after going under this bridge, completely losing the plot and also being a bit offset. The other units are virtually identical on the same path:

image_thumb60

Now, technically speaking on last night’s run my Fenix 6 Pro was running a public beta firmware version (including public beta GPS firmware). So I suppose that could be a factor, though honestly I kinda doubt it. Who knows. Basically anytime I made a turn, the Garmin doubled or tripled down on it:

image_thumb62

But what’s important here is that the COROS Pace 2 was rock-steady in its GPS track – easily nailing it, even under massive highways and train tracks like this here:

image_thumb64

So, what about the heart rate side of things? After all, this was an interval workout (kinda), so, here’s that:

image_thumb66

As you can see, the COROS Pace 2, in brown gets off to a rather brown crappy start, for the first 6 or so minutes it’s horribly off. Heck, even the Whoop 3.0 strap was more accurate, and that takes talent.

However, around the 6-7 minute marker it decided to wake-up and start tracking correctly. Shortly after that the Polar Grit X did its usual HR spike thing. Apparently it was feeling left out in the inaccurate game. But, let’s fast forward to the intervals to see how it handled:

image_thumb68

As you can see, the Garmin HRM-TRI chest strap responded most quickly (in purple) to the changes, while the Polar and COROS Watches followed the trendline fairly quickly behind it, matching pretty darn closely minus a few Polar quirks. The Whoop strap did what Whoop does best during intervals: Act confused and hide low. I seriously need to start/finish my video on it so I can stop spending money monthly on it. Heck, I’m sure Whoop probably wants that too by now.

Meanwhile, I did four short 30-seconds sprints towards the end of the run. Pretty similar pattern here, with the Garmin chest strap leading the way on responsiveness, but the COROS and Polar optical HR sensors following behind relatively quickly. The only exception though was the 3rd sprint, where the COROS completely missed the boat (similar to the beginning of the run), and basically just flat-lined. The Whoop wasn’t horrendous, but wasn’t great either.

image_thumb70

While the majority of the hard parts of the run were good, there was that initial lock issue that was kinda odd.

Here’s another run, this one around the forests south of Amsterdam. There’s some solid trees in here, and dense foliage. First, here’s the high level:

image_thumb48

You can see here I am under the trees, and things are pretty much identically the same between the units. The Grit X seems to swing wide a bit more frequently, but the Garmin and COROS units are virtually in lock-step throughout this run.

image_thumb50

And then in this more open field area, all the units are basically glued together:

image_thumb54

Same goes for other aspects of the run. Frankly, this run was super boring in that everyone agreed:

image_thumb56

Speaking of agreement, here’s the heart rate graph from this run. It’s comparing the COROS Pace 2 against the Polar Grit X, and then a TICKR X HR strap. As you can see, it near perfectly agrees with the TICKR X, save a bit of slowness at the beginning in the first 90 seconds, where you see that delay.

image_thumb58

But after that point, it’s like the two are buddies the entire time. As for the Polar Grit X? More of the usual optical HR spikes that I’ve consistently seen from it.

So what about elevation changes? Well, I don’t have much elevation around me here in Amsterdam, but I did last month in France. So let’s look at a run from back then – this one showing the changes over the route. The starting elevation points of roughly 5-6m are correct, rather than the Grit X assumption of 40m+. Beyond that it’s hard to say which unit was correct between the Garmin and COROS, they were mostly within a couple of meters at all times, with the Garmin appearing slightly more smooth (I didn’t stop), while the COROS appears a bit more blocky going up/down.

image_thumb52

But I think most people would find that level of closeness pretty acceptable (between the Garmin/COROS units). Again, I don’t have a ton of travel planned right now, given the world situation, so my elevation testing is semi-limited.

And as for the heart rate tracking on that run?

image_thumb72

Basically they were pretty close, but the Garmin was a bit more variable in a few locations – notably around the 3:45 marker, which was kinda odd. But from a COROS standpoint it basically mirrored the Wahoo TICKR X.

Now, what about a track run – let’s increase complexity for the GPS side. Tracks are often one of the hardest things to get right due to the near constant turning nature, and the fact that you can very clearly see in satellite imagery if the GPS track is incorrect. Here’s a track run I did using the Pace 2’s track mode:

image

And at first glance, you’re like: ‘Oh, the Garmin and Polar were pretty darn close to – everyone seemed to be on the track, right?

But then let’s show just the COROS:

image

That isn’t just one loop around the track – that’s 22 loops there – but it appears as a perfectly stable line. As you can see, the consistency of the line is spot-on. Really really really damn good.

However, the actual shape of the track is incorrect and non-aligned to where I ran. See, COROS ‘learns’ the track in the first few laps of any track effort, and in this case it appeared to learn the wrong track shape. There are numerous track shapes out there, and when it doesn’t quite nail the shape it’s more obvious. Does it impact distance accuracy though? Nope – it still got that spot-on correct. So that’s more of a visual thing than not.

image

As for the heart rate during that run – it was spot-on with the Garmin HRM-TRI chest strap, save however the first 5 minutes where it completely lost the plot. Totally missed the ‘we’re starting’ boat apparently. Then all of a sudden it locked and off it went. The brown is the Whoop strap (recorded on the Polar Grit X).

image

You’ll also see that on the 1st interval it’s a little bit latent on the start, as well as missing 3 out of 4 out of the short sprints at the end. You can dig into the set in more detail if you like, but that’s the gist of it.

Let’s switch to one of a few openwater swims I’ve done. In this case I have it compared against a Garmin Instinct Solar watch on the other wrist. Normally I have a reference track on the swim buoy, but the watch slipped down below the water surface line and was unusable data (first time in about a decade). Here’s that data:

image

What you see is actually very close to where I swam. There is a point though where both units struggled, but that was somewhat expected – I was treading water there for a minute or two taking photos/pictures, so that’s natural. I had stopped in a few other spots for a few seconds and no issues with brief stops.

image

I don’t have a reference track for heart rate, however, this one is honestly pretty easy – the COROS was horribly wrong. This was a lazy swim, as such, my heart rate was not 170-180bpm for the majority of it (the purple line). However, at the 23-minute marker you see my HR spike on the Instinct– this is actually legit. I swam hard for a section on purpose – so that’s real. However, later at the 33-minute marker as I got out of the water, that’s not correct and Instinct is wrong there.

image

Generally speaking, I look at swimming HR as ‘best effort’ when it comes to optical HR sensors. For some people it works well/OK, for some it’s a disaster. Measuring heart rate through water to your wrist is incredibly difficult, and the technology just isn’t super reliable yet.

Just for the fun of it, here’s another swim – the track was visually near perfect compared to the reference track:

image

However, it did have a bit of jitter to it – not quite as smooth as I’ve seen in a few other devices, so it increased the distance by about 80 meters. Again, pretty darn close though:

image

Finally, I’ve got a pile of bike rides with the COROS Pace 2. We’ll briefly look at the boringness of GPS accuracy on a road bike, and then switch to the pain of HR accuracy while riding. First up, the high-level GPS accuracy of that track:

image

I could copy/paste a million images in here – but the track is spot-on perfect from end to end. City and countryside, zero issues.

image

Inversely, the heart rate while cycling was a complete dumpster fire. Just as there’s little need to further analyze the GPS above, there’s little need to further analyze how inaccurate that purple line is below. And not just a little off – we’re talking really off.

image

Though, I did have one good ride where heart rate was very close:

image

Thus, it can get it right cycling if the conditions are right. That ride was warmer in temp, as well as more stable – which usually nets better results than rides with intensity shifts and cooler temps.

So ultimately things seem about what I expect for a generally good optical HR sensor minus cycling. A few stumbles here and there on running, but when push comes to shove the COROS Pace 2 seems to handle most situations fairly well. And usually if/when it goes wrong, it’s super clear it went wrong (like at the start of the workout).

As for GPS accuracy, it’s really spot-on. Super good. And that’s also what I tend to see from COROS lately. While COROS, Garmin, Suunto, and Polar are all using virtually the same GPS chipset, that doesn’t mean they have the same chipset firmware nor does it mean they have the same watch firmware to decide how to handle GPS quirks. Thus why you see differences play out in unique ways.

(Note: All of the charts in these accuracy sections were created using the DCR Analyzer tool.  It allows you to compare power meters/trainers, heart rate, cadence, speed/pace, GPS tracks, and plenty more. You can use it as well, more details here.)

Wrap-Up:

DSC_8455

As I said at the outset, the COROS Pace 2 is probably the most important watch COROS has released to date, and also the most important product they’ve made to date (they also make connected helmets). It’s a product that gets COROS back to their roots of doing what they do best: Being a well-priced alternative that offers solid features for a great price, while also being a bit of a disrupter.

Their wrist-based running power is a great example of that. Sure, Polar did that first – but Polar’s offering that has that is about twice the cost. And atop that, nobody integrates natively better than COROS with Stryd for running power, for those that want to go that way.

Which isn’t to say it’s a perfect watch. There’s elements of the app side that definitely need more love, more polish, and a bit more consistency. Other elements are too modal – like setting up training programs/workouts being pretty cumbersome at best. There’s some talk of TrainingPeaks workout integration, which might help there. And of course – if you’re looking for music, contactless payments, apps, or even following courses – those aren’t here.

Still, it’s hard to find any option on the market anywhere near this price point that’s as feature-packed, accurate, or with as good of battery life as the COROS Pace 2. Sure, they probably could have gone with a $249 price point, but I’d strongly argue that once you get there, then you’re within range of all the mid-range $279 Suunto/Polar options that have more cohesive online and app platforms. Albeit, none of them have running power in the wrist at that price.

In any case, as long as the features here fit what you’re looking for, then I think this a stellar option to consider – especially for someone either just getting into triathlon, or a runner who isn’t so fussed with all sorts of extra data metrics or features.

With that – thanks for reading!

  1. Lol that quick-release band is the same thing I bought for my Garmin Fenix 6s Pro, u can buy them for like €12 on alieexpress!
    More to the point, why does Coros hate music?! If they would add onboard music they would sell so much more and be a good alternative to much of Garmin’s watches!

    • I don’t think they hate music, I think it’s virtually impossible for them to do anything about it.

      Sure, they could relatively easily add standalone music support for MP3 files and such. But in 2020, almost nobody wants that (I know, someone will say they do – but realistically the market doesn’t). Instead, they want streaming support. And for that it takes millions of units in the marketplace for a Deezer/Spotify/Amazon/etc to even consider having an integration conversation. Not even Fitbit has offline Spotify yet (just music control).

      The same story is also true for contactless payments. It’s going to be near impossible for them to integrate there, since that requires a per-bank relationship. It requires Garmin/Apple/Fitbit going to literally every bank in the world and getting them onboard.

    • John A

      It would also bump up the price. I would love to run with music on my watch, but nothing integrates into Google Music/Youtube Music, and I don’t really want to switch. I don’t care of Garmin Pay either as my bank doesn’t support it.

    • ekutter

      I suspect another huge issue with music would be battery life. If they somehow got the streaming contracts, there’s a ton of battery involved with the streaming. But even just for local music, I assume the memory would have to be a lot bigger (I don’t know the specs here for sure). Bigger memory generally means going to off chip memory, which tends to be a battery drain.

    • Most people I know run with music and alot don’t always want to take their phone, If I say I don’t need my phone for music they don’t know that their are watches that u can put music on, alot of them now bought a Vivoactive!
      So I think it’s more of bad advertising/bad information!
      Now maybe I’m not the right guy to tell, I’m still using no music streaming service and mostly listen to podcasts!
      But as u say that it would be easy, than why not, it’s an easy box-ticker that Garmin does that they don’t, podcasts are so popular and they are easy to download!

    • Local music isn’t that bad for battery, on long road rides I listen to podcasts (with 1 bluetooth earpod) constantly for about 4 hours, on my Fenix 6s Pro I loose about 20% battery.
      U get about 29gb free space on a Fenix 6s, 300songs (about what I have on it) takes about 3gb so you can get alot of songs on it!

    • marklemc

      I had the Garmin 245 music so I could run with podcasts. I found it to be so cumbersome that I ended up getting rid of the watch. Running watches are good for running, mediocre for music support. Instead I got a little tiny Mighty player. About the size of an old ipod shuffle, works with spotify and is so small it easily fits into a tiny shorts pocket and it’s not noticeable.

      Much better solution than a watch that streams.

    • Mark

      I typically run with a SanDisk MP3 player. It has 8GB of space (micro SD expansion too).

      128kbps MP3 takes up about 1MB per minute – this particular watch has 64MB or space, so IF you delete the entire operating system and all your runs, just over an hour of MP3s. As Ray so nicely listed on the FR245 Music review, the 245 Music has 3.5GB of free space for music. More memory = more costs, something that seems to be high on Coros’ m.o.. The memory with a MP3 player alone would put this in the $250-280 range.

      Then add the license from Spotify

    • Andrew

      I still use an iPod Nano with Bluetooth headphones. It is so small and light that once in a pocket you would not even know you were carrying it. I think there are lots of people that don’t use streaming music services and prefer their entire music/podcast collection to be stored locally. If the iPod battery goes flat then no music for the rest of the run but my watch is still recording.

    • Eli

      For offline in spotify link to developer.spotify.com
      link to docs.google.com
      There have been a few small offline devices that support spotify. Delphin and also supporting Amazon music offline link to bemighty.com

    • I’m pretty convinced Mighty had managed to sign a Spotify contract years ago to get them access. It’s frankly the only thing that makes sense, since Fitbit and others have been unable to secure access. Obviously, Mighty (no matter how good it might be) is not even a rounding error in rounding errors in terms of why Spotify would agree (years ago).

      As for Delphin, it’s just running Android, and thus is able to download the Spotify app like any other Android app.

    • Stephen Thomas

      And after looking at the Delphin manual, I’ve revised my opinion about how much of a hassle it is to get music on a Forerunner 645 from a Mac. The Delphin has got to be the most horrible user experience I’ve ever seen documented; it makes the FR645 _almost_ seem reasonable.

  2. Alex Masidlover

    Suunto + cohesive online and app platforms ? 😉 Still great review – very tempted by a Coros to replace my Ambit3 when Suunto pull support for the Movescount App; if only they had an affordable option with breadcrumb navigation + back to start.

    I keep looking to see if I can pick up a second hand Apex, but I never see any come up – which makes me think their owners must like them…

  3. Miro

    Some nice features and a nice interface. Any chance they could be the target of an Garmin buy out?

    • John A

      I don’t know if they have anything of value to garmin. It doesn’t really do anything Garmin can’t do, it’s mostly the price that is beating them. Garmin could make a new 745 for $199 if they wanted and probably sell really well. They are the big dogs on the block and people will pay more for the name.

    • Agree, no real value to them from an acquisition/IP standpoint – except perhaps to make them go away.

    • _tido_

      Same feeling. But this could be an idéal target for Wahoo

    • Agree, Wahoo would actually have something to gain here, it would give them a massive jump into wearables. However, I think it’d realistically take 1-2 years for them to integrate and Wahooize what COROS has.

    • E Shaw

      And they’d have to rename the watches. PCE, APX, VRTX etc.

  4. Howie

    Where can this watch be purchased in Europe?

  5. John A

    I’ve been keeping an eye on a cheaper then a new garmin tri watch. This maybe the best one out there. It seems like garmin still hasn’t worked all the bugs out of that new Sony GPS chip.

  6. Will

    A quick release for a bike mount would add to its triathlon credibility.

    Other than that it’s great value.

  7. ekutter

    Ray, do you actually find running power useful for anything? I do most of my running on rougher trails, and there I don’t see any usage as the accuracy isn’t there. I can see some benefit on more consistent paved surfaces, but is it really providing anything speed and HR can’t provide for training purposes?

    Without direct measurement, it doesn’t seem like it will ever have the benefit power does on the bike.

    • Will

      Aren’t most bike power meter users road bikers rsther than mountain bikers?

    • JR

      In the case of both cycling and running, the idea of measuring “power” is to give you a precise snapshot of your metabolic output. Cycling power is “direct” in that it measures the strain on the pedals (or hub or crank or whatever) but what really mattes is that the power you put into the pedals happens to be directly proportional to metabolic output as measured by oxygen consumption in a lab.

      Running “power” as measured by Stryd is also directly proportional to oxygen consumption, so there’s no need for a “direct” measurement of how hard you’re pushing into the soles of your shoes. Nor is it totally clear that such a “direct” measurement would prove to be directly proportional to metabolic output.

      Stryd seems to work fine for me on any trail that’s fairly runnable, i.e., not much tougher than major trail ultras. Once you get to trails that are really part running, party hiking, then the numbers get screwier. Also, very soft terrain (sand or snow) will make the numbers useless.

    • Skookum8

      Your thoughts are correct and JR nailed it with his/her reply. I run trails and the fact that running power measurements can’t account for terrain variability makes it a non starter for me. Alex Hutchinson of Outside Online wrote about how Stryd factors in incline, for example, and it’s via a hack/swag that I don’t find rigorous enough.

  8. Dean

    Any data on the accuracy of pool swims ?

    • Sadly no pool swims this go around. I haven’t tried dealing with the pool situation here yet.

    • Mark Bauckman

      One key pool swim feature that the Pace 2 appears to be missing or I haven’t figured out from my first swim that Garmin multisport devices support is drill distance and time capture for non-stroke kicking drills. On Garmin, you work off the “Drill” screen and can view elapsed time and then manually select the correct multiple of the pool length to capture distance at the end of the drill. With Pace 2 now, it appears that if you’re not stroking, it ain’t counting. Hopefully this can be added in a future update.

  9. Rui Pereira

    One of the best typos in a while:
    …sitting on a coach flipping…

  10. Gilberto Baisch

    hi Ray,

    how about the screen visibility during workouts during night? I understood they are using some type of a dim backlight constantly. Is it visible enough during a hard workout? I tend to leave my fenix 5plus backlight on during night workouts… I’m looking for something simpler, but with enough visibility during night…

    thank you! nice review!

  11. Tim J

    Can the screen be flipped in order to wear it on the right wrist? If not, it looks like the dial would make it useless for left-handers.

  12. fl33tStA

    great review, looks like a really nice running watch,
    supplemented with with Karoo2 it could be a substitute for Garmin Forerunner & Edge, anyway
    I hope Garmin is now under a bit of pressure to support Native Power for running with Stryd

  13. Tomer

    Thanks for the review!

    How do you think it compares with Garmin 245?

    • It’s tricky. Super tricky.

      The FR245 is a runners watch. It doesn’t have a triathlon mode for example, nor support for cycling power meters. Whereas, this does both.

      Inversely, the FR245 has things like music support, and PacePro for runners, and all the physio stuff.

      Both have good Stryd support once you install the CIQ apps from Stryd. Which is sorta part of it. Sure, COROS has native support and it’s really damn good. But as Stryd has shown over the last few years, their CIQ apps are more than sufficient for 95% of the population. Obviously, if Garmin got on the wagon i could be so much better. But for most it’s good enough.

    • JR

      With music, the 245 is almost double the price!

      I get that it’s essentially impossible for COROS to get payments of Spotify. But I do think it’s feasible, and in line with what they’re doing, to try to get all the physio stuff. Body Battery in particular is something that has given me actionable intelligence. If COROS had something like that, I could see selling my Fenix 6 and replacing it with a Pace 2 for workouts and races and an Apple Watch for listening to stuff on easy runs. Heck, I’d even ditch the Stryd (pain to switch shoes, keep it charged, plus the new air resistance readings seem to make it less reliable than the previous version).

  14. ACE

    does HRM TRI/SWIM works with COROS in Swim Mode? does the watch pull the HR data after swim?

  15. Jon H

    It looks like it can only display 4 data fields at a time? Similar to the 735. I’d prefer 6 or more for the structured workouts i do.

  16. Evan

    If I understood correctly, without a Stryd pod – the watch doesn’t support the automatic creation of power zones, based on previous runs – that one can follow and display during a run ?.

  17. Francis

    How about instant pace? Is it as good as a Stryd? thx!

  18. Francis

    You have not mentioned anything about navigation, is that comparable to a Fenix?
    Thx!

  19. WoW42

    Hey, Ray,
    the training data from the watch can be saved as a file ( .fit, .fitbit, fitfile, fit.log etc.)
    can be exported, PC, Laptop ?
    Thanks

    • You can export as a .FIT file from the smartphone app (as well as .TCX/GPX/KML/CSV). But the device itself won’t show any files enumerated when plugged in via USB to a PC. Interestingly though, it does enumerate two empty folder as a USB drive – so there is some potential there. However, it’s likely they do all file processing app-side, rather than on-device.

  20. Steven Booth

    Sounds like underwater optical HR just still isn’t accurate. Bummer! Guess I’ll stick with my old-ass 920xt until there’s a watch worth buying for swim/openwater swim HR. Chest strap not an option for me, I just doubt it will stay without wearing a “top.” HR isn’t that useful in swimming….but, I’ve been swimming since I was 6 and I’ve never had HR data for any swim ever. It would be nice to see how my PE lines up with my zone-HR.

  21. csabot

    Quick question – Are there issues with doing sports that are not part of the the standard set? I do a lot of nordic skiing and roller skiing in addition to the standard swim/bike/run. Are there any potential performance related issues or is it merely a matter of labeling. I would sync with Strava which does allow for these sports. I assume I would need to manually edit each activity in Stravea to select the correct sport.

    Thanks so much!

  22. Oskars

    No video with menu walkthrough?

  23. Tyler Martin

    I know you don’t recommend using them unless you have to, but it would be nice to see comparisons of the UltraMax GPS mode. To the regular GPS mode and to other brands Ultra modes. I can’t say I would need this often, but during the occasional race it would be useful.

    Thanks for the super in depth review as always.

  24. James

    Would you recommend this over the Suunto 5 as a triathlon (run predominate) watch? The Suunto is available now for near as matters the same cost of the Pace 2 (available in October). Grab the Suunto on sale or wait for the Pace 2? Thanks for all the great info, as always!

  25. Juro

    Am I the only person that has a problem with the fact that Coros is a ripoff of Garmin design-wise? From box through interface to the app design.

    • Dean

      Exactly how much do you think a sports watch can differ? You cant reinvent the wheel.

    • Suunto, Polar, and others seem to be able to reinvent the wheel…

      Though, I would say the app design is notably different for the most part.

    • Andrew

      Which Garmin watch has a digital dial + button?

    • I believe you’re looking for the Apple Watch there. Complete with near identical duplication of the activity rings in the app.

      Juro’s comment is accurate. The Pace 2 is less of a lookalike than all previous COROS watches, but the fonts, icons, etc are all exactly the same.

      I didn’t focus on the duplication much in this review, I think I’ve covered it pretty well in the past. But if someone wants to argue it, it’s a battle they’ll quickly lose.

    • Mr T

      No. Are you bothered most SUV look alike?

  26. fiatlux

    Seems like a great deal, too bad about the total lack of navigation. I am increasingly using the breadcrumb trail navigation features of my good old 920XT to explore new cross-country runs.

  27. Circe

    Drill-mode (or something similar) in swimming/pool app?

  28. Pepe

    Hey Ray, can you add the .fit file from Coros Pace 2 + Stryd?

  29. ChrisTexan

    Ultramax section, you said something like “hold the lower LEFT button”… assuming that should read lower “Right” button.
    I was going to ask if this will rebroadcast from a BTLE HR strap, to ANT+?
    You mentioned it broadcasts it’s own HR readings via ANT+, so just curious if it was setup using HR strap data, would it also rebroadcast that. (Not sure how many need that, I realized before writing this, using an H10, I get both broadcast (so don’t really need it to be “re-broadcast”) but for H7 users, or other branded BTLE only straps (if such are out there) might be nice.

  30. Eli

    Whats the AI Trainer? Is that a training plan then changes as you go sort of like Xert?

  31. acousticbiker

    Thanks as always, Ray!

    An intriguing watch to say the least, especially at 1/3 the weight and price of a Fenix 6.

    – Can you please comment on build quality?
    – Anything you can share about Garmin’s plans for running power?

    • Build quality feels good. It’s plastic no doubt, but feels fine.

      I’m not aware of any further plans related to Garmin and running power.

    • Andrew

      Your review doesn’t mention the screen being Corning® Glass (taken from Coros website).
      Do other wearables at the $199 price point have plastic or glass screens?
      I am notorious for scratching new watch faces so would like to know how resilient the screen is?

    • I typically don’t get into glass/plastic coverings in most cases, unless there is SKU differences.

      In any case, Gorilla Glass is actually pretty common these days at this price point. For example the Fitbit Versa series as it at $169.

  32. Mike H

    I’ve been looking for a cheap way to get more accurate running power for TRIMP so I don’t risk overtraining if I mix cycling and running workouts. HR zones just seem to noisy to be effective. I don’t give a flip about music / contactless payments etc or even nav – I always have my phone – and hate paying for stuff like that I’ll never use.

    This product seems laser focused at me. I was looking at the new Polar watches but at half the price this is a no-brainer. My only concern, and it’s a small one, is I don’t see anything about Google Fit integration for the all-day HR / sleep stuff. (Workouts come through Strava.)

  33. JOSE LUIS

    Calculate the power zones the pace 2 chorus automatically or you have to have stryd for it

  34. Mike C

    Thank you Ray. When talking about the track you mention you like to use manual lap. Are you able to manually lap to progress in a workout? (E.g. On my Garmin I preprogram my warmup to manual lap press to signal the end of warmup and proceed to the true workout as my warmup times vary depending on how I am feeling and the type of workout I am doing. I also manually lap if a repeat goes horribly wrong and I want to go to the recovery early.)
    Also, when connecting to Stryd you mention you are able to input in a calibration factor. Is there a maximum? (When running on my manual treadmill I use a calibration factor of 122%. I can do this on my Garmin but I know the Stryd Apple Watch App limits to a 105%.)

  35. Rohit

    Great in-depth review !!!!
    What material is the Digital dial made off and is it rugged enough and how responsive is it.I saw a couple of videos on youtube where users had to rotate the knob many times just to move over from one option to the next one. I liked most of the features this watch has to offer but am not a fan of the digital dial. Without the digital dial i would have probably purchased this watch without a second thought.
    Also how thick is the screen glass. Is it scratch resistant/proof?

  36. Andrew

    Is there HRV?

  37. Andrew D

    Hi Ray, great review. I’m in the market for a new watch after my second 735xt stopped working after the seal leaked.

    If you had to choose between a Garmin fenix 5s refurb for $240 and this watch, which would you go for? Running power seems like a great plus for the COROS, but there are a few other advantages with the 5s too. For context, I’m mainly focused on running right now, but would like the ability to swim and hike as well as a benefit.

    • Will

      Horses for courses. In the UK there is still almost £100 difference between Pace 2 and refurb 5s.
      If you’re a regular runner with power then the Pace 2 is the way to go. Garmin does not support power based running workouts. However Garmin IQ apps are pretty good. Also there are a lot more bells & whistles on the 5s, great if you use them. Breadcrumb navigation is also on 5s. Think of Pace 2 has a more focused triathlon watch.

    • Richard Shepherd

      If you consider GPS accuracy in open water swimming important then I’d avoid a 5 series. Ray tested the 5 and it was all over the place. I have a Descent Mk1 for SCUBA based on the 5X and it’s equally as horrible whereas my FR935 is much better despite the same chipset. I suspect it has to do with case thickness and antenna placement as the watch has to get some kind of GPS fix in a very small timeframe.
      My Pace 2 was due to arrive on 10th September but I’ve received an email form Coros saying they’ve had so many pre-orders thay can’t ship mine until sometime next week.

  38. YKW

    I am curious how this compares against a stryd in place of a footpod for running on a treadmill.

    I am looking to get a footpod, but this is the same price as a stryd and if it can measure speed/cadence and transmit to Zwift – honus

  39. GraemeW

    Does the swim data sync with Strava (or other online services)?
    Similarly – does the triathlon mode sync with Strava (or other), either as individual activities or as some sort of combined activity?

    The Xioami Amazfit Stratos 2 fails on both counts. Pool swims appear in Strava simply as an activity duration, with no lap count or any other stats.
    Triathlon activities fail to sync at all.

  40. Jose Luis

    This watch Synchronizes individually with PowerCenter without stryd association

  41. David

    Great review. Thanks for the job done.
    Do you know it is possible to use it for swimrun, I mean to configure several transitions run, swim, run, swim, … and record all in one single activity ?
    Thanks !

  42. Jason

    Just received a polar ignite. I’m a very novice runner and was looking for a fitness watch to compliment run , bike , mountain bike. I’m learning what all the different metrics mean and how to use to better my workouts. Also love to upload to strava!

    How does the COROS 2 compare to the ignite ? Should I ship back 🙂 I do like the polar flow app but thinking I could do the same with the coros? Help! Head about to explode lol

    • Phil

      Polar Ignite has a brillant display which is optimized for Indoor Training. Power consumption is high; battery runtime of Ignite not as good as Vantage M for example.
      If you mostly do your activities outside, then I would change to Vantage M / coros Pace2.
      If you are ok with battery & display readings outside then stay with Ignite.

  43. Wayne

    Thanks again for all your hard work and excellent reviews.
    I have the Pace 2, and overall I find it fantastic and very accurate (I use it with Polar H9 ANT+ connection.
    One thing really baffles me, is why oh why when during interval sessions, does the watch automatic switch back to a ‘preset’ data page, even when I have all 5 pages setup and put it on ones I need, yet every single lap it switches back?
    The autos roll is off, and after a few days of conversations with Coros via social media messages, they still have not told me why they have set this, as when running hard it is near on almost impossible to scroll that wheel back to the data page I’d already set at the start of the session. Super annoying and unworkable when like my last session was 16x 200s , with 1 minute jog recoveries, so yes, that was 32 times of trying to a scroll back to the page I require while running at a good crack.
    Other than this issue, the watch is excellent, but for me it will go back in the box, unless I hear Coros gets this sorted.

  44. Mike Trudell

    When completing a power based structured run, how well can you feel/hear the alerting either at an interval change or when falling out of a target zone?

    I’ve used both the apple 5 watch and the stryd CIQ app and both are awful at alerting via a sound or haptic while completing a structured run.

    Thanks!

    • Wayne

      I had no problems feeling the vibrate in any event, I have music in my ears mostly, but when I didn’t have music On I could hear the tones as well as a good vibrate, no problem there for me.

  45. Kevin Tan

    Hi Ray,
    You mentioned the ability to switch off auto lap. May I know how can I switch if off please? Been looking at both the app and the watch but couldn’t find the place to switch it off.

  46. Kevin Tan

    This is after I scroll down a line.

  47. moment-of-momentum

    So here’s a simple question to what would make me buy a Coros Pace2 instead of the upcoming Garmin 745:

    How does it handle GPS loss/drop mid-run?

    Because after years and years, Garmin still handles this horribly and never fixes it, never trying to re-gain GPS lock, never notifying the user in any way that GPS location has been dead for miles and miles despite going into treadmill mode and recording every other movement/metric.

    If the Pace2 just alerts the user GPS has been loss, that a “buy” right there given all the other abilities are mostly on par (if it tries to regain lock, that is even better).

    • I’ve honestly not seen what you’re describing for GPS lock from any company in the last 5-8 years. I run and/or ride through three sets of tunnels/bridges daily that GPS is lost, and it always resumes each time within seconds. In fact, it’s something I usually note if there’s any issues in the GPS accuracy test showing the entry/exit points are spot-on.

      What unit do you have that’s doing this?

  48. moment-of-momentum

    my fenix5s loses GPS mid-run at least twice a month (daily use) and never regains, no tall buildings, no weather, just goes away random

    the worst part is you never know until the run is done and you’ve uploaded, there is no indication on the watch at all that it went into treadmill mode permanently

    gamin support is silent on the issue

    hence maybe Pace2 if it handles this better

  49. St. Peter

    Reading / watching different reviews about this watch makes me feel like abandoning my Fenix 6s and converting to Coros 🙂 I do tons of running (lots of structured workouts), walking and XC-skiing or rollerskiing / biking / swimming from time to time. The only thing holding me back is lack of maps 🙁

    So, I guess, I have to wait for some updated version of Apex coming out. I know, I know that will not happen this year… Maybe next year? Do we have a chance of it Ray? (or someone else who might have an educated guess on the matter :))

  50. Mark

    Hello DCR!,

    Which do you think would be a better purchase: the Pace 2 or the Apex? I read your review of the Apex from 2019 and there seemed to be a few glitches. I wasn’t sure if maybe those were worked out with software updates.

    Mark

  51. madmalkav

    I understand this is a very specific / niche question but, how good is this watch at receiving notifications with emoticons and asian characters? Garmin will require you to buy an special version of their watches to get support for asian languages and I find that nothing but a greedy paywall.

  52. I like smart watch. where can i purchase

  53. Felix Alicea

    Hi Rainmaker:
    I’m curious how many of your readers have attempted to use the Coros Trade-In Program to purchase the Coros Pace 2 watch? The reason I’m asking is that I have tried two times with watches that were in very good condition, for instance, the Coros Pace One and the Polar M430 and even though they say they will give a credit of up to $100.00 to your purchase they seem to low ball you with half that price. They offered $50.00 for the Coros Pace One and $40.00 for the Polar M430 watch. These watches are in excellent condition. I would rather sell them on Amazon or eBay. All the best.

  54. Will

    Coros 2 + Stryd bundles are available now from New Running Gear. £333. Further 15% discount codes work too. Cracking deal either way.

  55. Felix Alicea

    Hi Rainmaker:
    I just wanted to know if anyone has taken advantage of the Coros Trade-In program and what type of results they have had. Were they satisfied with the reductions offered during the process? I tried on 2 occasions with two different watches that were in excellent shape and was low-balled on the estimate. The result being I did not trade-in the watch for the lower price. Has anyone else had this experience?

    • Andrea Guss

      Felix I am wondering the same. Also I would be interested in purchasing your Pace.

    • Felix Alicea

      Hi Andrea:

      I haven’t decided what I will do yet. And, I am very happy with the Coros Pace One to date. But If I decide to finally purchase the Coros Pace 2 and if you’re still interested I will let you know. All the best.

      Felix

  56. Tom Jeff

    Hi there!

    I’m in a dilemma between the Coros pace 2 and Suunto 5.There is a discount for Suunto,so both are at the same price.I run a lot,sometime on trails,cycle and swim.
    I favor Suunto for its looks and moble app,but Coros Pace 2 for its battery and running power features.
    Which would you go for?Help Ray! :)))

  57. L.J.

    Hi all,
    does the pace 2 work with other footpods than stryd? (stryd is way too expensive for my needs)
    Can’t imagine that speed / distance measurement on a treadmill is reliable without footpod. I’m also confused about the Coros POD. How to measure e.g. stride length without GPS while mounted on my back?

  58. Mark

    Ray, can you extrapolate about the multisport/triathlon feature more? I read/heard somewhere that you can customize multisport races so they aren’t always SBR – so you could set up a duathlon run-bike-run, or a aquabike, or aqua run, or what ever funky race you’ve got planned (SUP-run?, Eppie’s Grat Race in Sac [run-bike-kayak])

    As a non-swimmer, it might be right up my alley 😉

  59. Mike PT Guy

    anyone have any experience with their return policy. I am looking at this watch seriously and I see it they advertise a 30 day return policy.

    I was thinking of trying this for 30 days to see if it works for me

    Thanks in advance.

  60. csabot

    Any thoughts on this vs. a Garmin Instinct? I don’t really need run power. I bike, run, roller ski and cross-country ski. I like how light this watch is but wonder if the Instinct could be a better all-around option?

  61. Felix Alicea

    Hi Rainmaker:

    Do you have any idea when Amazon will be selling the Coros Pace 2 watch?

    All the best,
    Felix

  62. JR

    Does it have both audible and vibration alerts? Vibration alarm clock?

    Does the Garmin hr tri strap work with the corus pace, and can you use its features?

    How much does it weigh without the strap? I have a watch with silicon strap which is a few grams heavier than Pace 2. So my watch may be the lightest if I go with nylon.

    Hi@all, can anyone tell me which power settings (without connected to stryd etc.) only by using the pace 2 itself are available?

    – is it possible to set “critical power” without pod?
    – is it possible to set & use power zones without pod?

    As far as I realize there is no data field for power zones for workout interface “running”.
    May be I’m wrong. Thanks for your advice.

      can anyone help?
      How can I change physical values like body weight or hrmax, treshold etc.?

      You might have better success by simply contacting Coros and asking them.

      link to support.coros.com

      But the Coros iOS app allows you to set body weight and heart rate zones, among many other things.

      Coros Consumer Support answers quickly. Here it is:

      All COROS watches now support running power from the wrist without the need of any accessories. Supported data types include Running Power, Avg. Power, Lap Power, 3s/10s/30s Avg. Power, however Critical Power data is not supported without pairing accessories. If you have a Stryd pod paired to your COROS watch, you can enter Critical Power manually on the COROS watch via System > Accessories > Added List > STRYD > Critical Power.

      If you would like to receive running power zone alerts, set up a structured running workout and choose Power for the intensity setting. Click here to learn more about structured workouts.
      There are 3 different heart rate zones for you to choose from. You can select the one that better suits your training needs from the drop-down menu located on the top of the page.

      Max Heart Rate Zone is the most straightforward one and can be applied to all users. Adjust the Max Heart Rate to change the zones accordingly. You can also tap and customize individual zones.
      Heart Rate Reserve Zone is favored among advanced athletes. Adjust the Resting Heart Rate (RHR) and Max Heart Rate to change the zones accordingly. You can also tap and customize individual zones.
      Lactate Threshold Zone is favored among advanced athletes. Adjust the Lactate Threshold to change the zones accordingly. You can also tap and customize individual zones.

    Wait… so this boils down to…

    “Except for swimming HRM, the Coros Pace 2 is great at tracking HRM on all sports other than cycling.” ? ?

    Those are literally 2/3 of the triathlon events! Why didn’t they make the summary?

    • tony McNamara

      Sorry, that was a bit terse. 😉

      Unless I misread, you showed that HRM for both swimming and cycling were way off in the analysis. But the summary was quite positive. Am I blowing the HRM for cycling and swimming out of proportion? (I’m a swimmer and cyclist, but really don’t enjoy running.)

    • Yeah, I guess for the most part nobody gets swimming optical HR on the wrist correct except sometimes by pure dumb luck. So I weight that super low. And cycling isn’t that different, it’s really hard to get outdoor cycling correct. Some watches pull it off so-so, but nobody does so ‘well’. So again I weight that a bit lower.

      Whereas I weight running, indoor cycling, and other indoor non-swimming activities higher since they’re more common.

    • Oh – and thanks for being a DCR Supporter. Welcome aboard!

      Thank you. I’m amazed at the depth of your reviews.

      I gripe about Garmin’s connectivity. I had to return a Venu because they blocked me, and several other people, for an entire week, not knowing how long it would be. I spent a long time working through this with them; the support people really don’t have any way of talking to ops, and ops doesn’t understand CloudFlare whitelists. A day after I returned the Venu in the return window, access came back, but that’s a massive risk when they don’t understand their own stuff. And a quick search will show this isn’t uncommon for them.

      But I was impressed with it otherwise. The wrist-based HRM seemed spot-on, including manual checks.
      Stroke detection was iffy – I have a classic strong butterfly and it even called that breastroke about a quarter of the time – but I was still impressed by it. Similarly, distance was often off but close enough.

      The only actual gripe I had, other than that their cloud issues, was that in swimming the Auto-Rest detection is good but… it kicks in fast and hides the heartrate, and you can’t get it back except by resuming swimming.

      Hence the concern about the Coros swimming HRM. It may be that I just have to bite the Connect risk and go back to Garmin.

    Could you comment on screen legibility of the Pace 2?

    I have a Coros Apex, and while it is excellent in terms of battery life (I run long races!) and general functionality, IMHO its biggest weakness is the quality of the LCD. Whereas Garmin screens seem to be consistently visible in bright sunlight, I’ve found the legibility of the Coros screen is unreliable: I have to tilt my wrist to just the right angle to be able to read the display.

    The legibility is not horrible, but Garmin screens (I’ve tried many over the years) are far better in this respect.
    Coros unfortunately make the situation worse with smaller fonts and cluttered screen layouts.

    I went back and checked original Apex review, and was surprised that you never commented on this.

    • I’d say it’s good. Not quite as high contrast and crispy as some other watches, but mostly good.

      My challenge is honestly that I have pretty good eyesight, so something has to be really bad for me to notice it. :-/
