Week in Review–July 1st, 2017


The Week in Review is a collection of both all the goodness I’ve written during the past week around the internet, as well as a small pile of links I found interesting – generally endurance sports related. I’ve often wondered what to do with all of the coolness that people write, and while I share a lot of it on Twitter and Facebook, this is a better forum for sending it on to y’all. Most times these different streams don’t overlap, so be on the lookout at all these places for good stuff!

So with that, let’s get into the action!

DCRainmaker.com posts in the past week:

Here’s all the goodness that ended up on the main page of DCRainmaker.com this past week:

Sunday: Week in Review–June 25th, 2017
Monday: DJI Spark In-Depth Review
Tuesday: 5 Random Things I Did This Weekend in Sardinia
Thursday: Polar M430 In-Depth Review
Saturday: Tour de France 2017–The Trainers, Power Meters and Gadgets of the Pro Peloton

Sports Tech Deals This Week:

With the start of July brings a fresh wave of new sports tech deals.  More interestingly, some of these are actually Europe-specific, which is a rarity around these parts!  I’ve noted which ones specifically are Europe-focused.

4iiii Power Meters - From $399 Normally20% off
Apple Airpods (2nd Gen) - $15 off$144I use AirPods primarily when I'm travelling just to listen in airports, planes, etc... I don't tend to use these for workouts due to them falling out.
Apple Airpods Pro - $15 off$234Yup, these are the new noise-cancelling ones that don't fall out of your ears. I haven't tried them yet, but lots of people seem happy with them.
Apple Watch Series 3 (38mm)$169⚡ This unit recently got reduced to $199, and now it's down to $169. Walmart is also offering it for $129 on Black Friday weekend.
COROS APEX GPS Multisport Watch - Normally $29920% off
COROS Vertix GPS Multisport Watch - Normally $59920% off
Elite Drivo II Smart Trainer - Normally $1,19920% off

Elite Tuo Smart Trainer - Normally $49920% offNote: I haven't gotten this trainer in to test yet. It's one I'm super excited about after trying it at Eurobike, but I have no idea on things like accuracy yet.
Feedback Sports Omnium Over-Drive Portable Trainer - Normally $39920% off
Garmin Cadence Sensor Gen2 (Dual ANT+/Bluetooth) - $5 off$35Note: This is a random Amazon deal that will probably disappear. But, it's a great sensor for Zwift usage as it's not just dual ANT+/BLE, but dual-BLE atop that (so it can do two concurrent Bluetooth connections and unlimited ANT+ connections).
Garmin Descent MK1 - $200 Off$799
Garmin Edge 1030 - $150 Off$449
Garmin Edge 1030 Bundle - $150 Off$549
Garmin Edge 1030 Bundle- $150 Off$549Note: Includes Extended Mount, Standard Mount, Speed Sensor, Cadence Sensor, and Premium HRM

Garmin Edge 130 Sensor Bundle - $50 Off$199
Garmin Fenix 5 Plus (5/5S/5X) - $150 Off$449⚡This is a strong deal on the Fenix 5 Plus series. This is for all models/variants. Obviously, the Fenix 6 came out two months ago, so don't expect major new feature updates on the Fenix 5 Plus - but still, it's a strong option.
Garmin Fenix 5 Series - 34% off$399Down to $399 is a substantial deal. It's the Fenix 5 (non-Plus), so don't expect much in the way of major firmware updates. But still, at that price it's solid.
Garmin Forerunner 735XT GPS Multisport Watch - Normally $34920% off
Garmin Forerunner 735XT GPS Multisport Watch - Normally $349$219-$236⚡ This is a fantastic deal right now. The price on Amazon is fluctuating a bit, but either way - by far the lowest we've seen. Awesome if you're looking to get into triathlon or just want a really capable running/cycling/swimming watch.
Garmin Forerunner 935 - $100 Off $399
Garmin Forerunner 935 Tri Bundle- $100 Off$549
Garmin Forerunner 945 - $100 Off$499⚡⚡ This is a super hot deal - first time we've seen the FR945 on sale.
Garmin Forerunner 945 Bundle- $100 Off$649⚡⚡ This is a super hot deal - first time we've seen the FR945 on sale. Note: Includes HRM-SWIM, HRM-TRI, Quick Release Kit
Garmin HRM-DUAL (ANT+/Bluetooth Smart Strap)- $10 off$59⚡ This is my favorite chest strap these days (ANT+ & two concurrent BLE connections). It's never on sale, so this is basically just Amazon offering it at a discount for fun. Take it and run - probably won't last long.
Garmin HRM-RUN (with Running Dynamics) - $20 off$79This is the odd (and unheard of) Amazon sale. This strap includes Running Dynamics, but is ANT+ only. Honestly, unless you really want Running Dynamics, I'd recommend getting the HRM-DUAL instead (it's dual ANT+/BLE).
Garmin HRM-TRI/HRM-SWIM Bundle (30% off!)$139Another rare Amazon sale on the HRM-TRI & HRM-SWIM straps. Also individually for 30% off too at same link.
Garmin Instinct - $100 Off$199
Garmin Instinct Tactical - $100 Off$249
Garmin Instinct Tactical- $100 Off249
Garmin RD Pod (Running Dynamics) - 17% off$57Allows you to get not just Running Dynamics metrics, but also running power, on Garmin devices.
Garmin RTL510 Varia Cycling Radar - $50 Off$149⚡⚡ These days this isn't just a Garmin thing anymore. Wahoo and Hammerhead also support the radar, with Stages coming soon! Also, fun fact: This is *by far* the most ordered item on this page on the opening day (Friday, Nov 15th, 2019).
Garmin RTL510 Varia Radar Bundle (Radar + Display) - $50 Off$249
Garmin Speed Sensor Gen2 (Dual ANT+/Bluetooth) - $5 off$35⚡ This isn't a huge deal per se, but it is my favorite speed sensor for a commuter bike as it just quietly tracks all your mileage in the background and syncs it to your phone. Also, this falls in the bucket of 'random Amazon deals that will probably disappear'.
Garmin Tactix Charlie- $150 Off$599
Garmin Vector 3 - $200 Off$799⚡ This is the lowest price we've ever seen Garmin Vector 3 at. I don't expect a new version anytime soon - just a good holiday deal.

Garmin Vivosport GPS Band - Normally $16920% off
GoPro Hero 7 Black with 32GB - Normally $32920% off⚡ ⚡ While the newer Hero 8 Black is great, for the price inclusive of the 20% discount - this Hero 7 Black is an incredible deal.
GoPro Hero 8 Black with $50 REI card$400This is the best deal we've seen on the new Hero 8 Black for purchase today (if you're an REI customer). You get a $50 REI gift card to spend.
GoPro Hero 8 Black with 32GB card, Head Mount, Shorty Stick $329BLACK FRIDAY WEEKEND ONLY! This is a huge deal, as the GoPro Hero 8 Black itself is $399, and then the Shorty Stick is another $40 (my favorite GoPro accessory), and the head mount in the $30 range, and the 32GB card in the $10 range. Again, deal doesn't start till Nov 28th.

Suunto 9 G1 GPS Multisport Watch - $120 off$279
Tacx Flow Smart Trainer - Normally $36920% offThis is a great little starter unit that supports full control in Zwift/TrainerRoad/etc... It's not super powerful (meaning, it won't without a 500w ERG mode session), but if you're just getting into things it's not a bad place to start at all - especially on sale. Note: REI Members-only sale.
Tacx Flux 2 Smart Trainer - Normally $89920% off *Deal with REI or Clever Training - Members save 20%, with the link here! I don't expect it to last (but hope it does!).

Velocomp AeroPod Aero Sensor - Normally $49920% off
Wahoo CLIMB Accessory - Normally $59920% off
Wahoo Headwind Fan - Normally $24920% offThis is one of those units that is undoubtedly expensive - yet everyone who has one loves it. Including myself.
Wahoo KICKR + CLIMB Bundle - $200 off!$1,599This is a simple bundle of the Wahoo KICKR 2018 + the KICKR CLIMB, for $1,599. Pro Tip: Keep in mind that if you have two people in your household, both CT VIP members (which is free), you could achieve this same thing for less by purchasing both units individually at 20% off. However, if you lack friends, then this is a solid deal!
Wahoo KICKR 2018 Smart Trainer - Normally $1,19920% off⚡ One of the top three trainers out there. There's no better deal on it anytime of the year except the VIP sale.

Also of note is that ELEMNT $80 rebate for the larger unit.  Helps to equalize the price compared to the smaller BOLT.  Both contain the same software, though the larger unit has an additional LED stripe.

Stuff that I found interesting around the interwebs:

Here’s a not-so-small smattering of all the random things that I stumbled on while doing my civic duty to find the end of the Internet.

1) A Breakdown of of a Tour de France Team Bus: Neat little look at what it costs to run a TdF team bus. (via My Dad)

2) Fitbit Sleep Study: Pretty cool charts and breakdowns of how much and how different millions of Fitbit users sleep on average, divided up by age groups and all assortment of metrics. (via Ernesto R.)

3) I’m over on the latest Cycling Maven TDF Vlog!  Boom, now I’ve made it!  Awesome to run into him while running around.

4) Tour de France massive infographic: Ok, this is the week of infographics – but if there’s any infographic to look at, it’s this incredible four-page one put together by Le Tour themselves.  I think I read through it for 10 minutes.

5) Science people – please stop doing this: Yet another study doubles-down on doubling optical HR sensors per wrist.  Just don’t.  Really, don’t.

6) Yes, EPO impacts sports performance: Why do you ask?

7) The Pain Cave: A look into an apparent obsession with it and everything about it.

8) Using drones to study America’s Cup Riders: This is pretty crazy. Though, it doesn’t surprise me.  Just this week I got asked questions about which drones would be best for doing form studies on rowers. (via Robin Crimp)

Sports Technology Software/Firmware Updates This Week:

Each week I quickly highlight some of the new firmware, app, software and website service updates that I see go out. If you’re a sports technology company and release an update – shoot me a quick note (just one-liners are perfect, or Tweet it at me is even better) and I’ll make mention of it here. If I don’t know about it, I won’t be able to post about it. Sound good?  Oh – and if you want to get a head start on things, this page is a great resource for watching Garmin firmware updates.

Garmin Fenix 5/5S/5X/Chronos BETA firmware update: A couple more new features, and a boatload of tweaks/fixes.

Polar M430 Firmware Update: Fixes some bugs, fully implements GPS-A caching


Thanks for reading!

    Any chance you could ask Garmin why the 935 preferentially syncs via (slow) Bluetooth rather than (speedy) wifi even when I’m 10 feet from my router? I end up turning off Bluetooth just before saving to force it. Damn annoying!

  2. rehmn

    Erythropoetin doesn’t have immediate effect, like other hormones (adrenaline, ADH, Oxytocine, etc.). It is stimulating the bone marrow to produce red blood cells. This production takes time.
    If you read somewhere, that during a race Lance applied an EPO to go faster or in the mentioned study/experiment users noticed difference in performance, it is a lie!
    If you want to increase your haematocrit (ratio between bood cells and plasma), you must plan long term. By means, you must calculate the buffer dose and the maintaining dose as well, the time intervals you need to apply EPO and also the level of concentration of the red blood cells you want to reach without side effect (like, avoiding thrombosis).
    This is a proof that Lance was using EPO for years and his physician set up the intervals, because he couldn’t do it alone…
    And by the way, EPO is used as supplementary treatment at breast cancer, because the cytostatics used for treatment are destroying the bone marrow and as the result, the number of Erytrocytes are decreasing.

    That’s all you need to know.
    Every other publication round EPO are empty words… blablabla…

  3. JCRunner

    Maybe Garmin can start focusing on fixing the Fenix5 Ant+/Bluetooth and GPS accuracy issues. I can’t even use a Garmin HRM chest strap, let alone my $200 Stryd footpod, which is currently sitting on my desk due to Garmin dropouts. Of course I really wouldn’t need the Stryd anymore if the GPS and instant pace were more in line with the past Garmin devices I’ve own.

    Garmins response everytime: “Please wait for updated firmware..”

    • The Stryd thing is a known of course, but the HR strap thing shouldn’t be happening. I’d push back on Garmin support to either replace your HR strap or your watch.

    • JCRunner

      Thanks for the advice. Garmin is remaining firm that my device is fine, and the ANT+ / GPS issues will be addressed in future firmware updates. Unfortunately, this isn’t my first rodeo trying to get a replacement. My FR235 had a faulty oHRM, and it took me nearly two months to get it replaced.

      Based on my recent conversations with the Stryd folks, they seem to believe this is a hardware issue with a weak signal. I wonder if Garmin could implement a “High Accuracy” mode on the Fenix, which will sacrifice some battery life to boost the hardware signals. I would be more than fine with that.

      It bums me out that Garmins flagship device, at $700 USD for my Fenix 5 sapphire, is still having issues. I’ve been using my wife’s FR235 for the more important training runs and races.

    OT: Is there any cycle computer or gps watch compatible with Galileo satellites?
    I checked http://www.usegalileo.eu but no sport device is listed.

  5. Tom Carter

    One of the Rowers here you spoke to about the Drones – In the sport we are starting to see more and more used to get some cool shots, my own video which I filmed a few weeks back came out really well for example

    link to youtube.com

    That was a Bebop 2 using a follow me app on my phone, cam out rather well

    The main concern is landing/crashing into the water but there do seem to be more waterproof drones appearing which would be more suitable

    • Gotta say – that footage is astounding, especially for just being 720p.

      Well done!

    • Tom Carter

      Thanks! One of those days where the conditions were just perfect for getting good quality footage, even as an amateur.

      This last week the Henley Royal Regatta has just been and gone which has a much more professional set up and has fully embraced Drones, 360 cameras etc – check it out here

      link to youtube.com

      A good example of the drone footage is in this video from 5mins in where you can see the crews racing and the people on the river and bank enjoying the event. The Drone is a specially built drone carrying a Sony P1 and livestreaming over UHF for the live youtube video – amazing stuff

  6. Mike Richie

    In fairness, in your “Science people please stop doing this …”, they were not testing optical HR, but activity trackers (including 2 phones on belt) and were also switching locations, so I’m not sure that it wasn’t a perfectly good approach (there is no link to the full study). The tweeter, however, seemed to have problem with it, but I’m not sure he isn’t just wrong.

  7. Struan Lownie

    The clever training UK discount doesnt seem to be being applied to an Edge 1000, Its shows as £439.99 on Clevertraining but only £325.59 on Amazon.co.uk.

    Am I missing something?
