Week in Review–June 30th, 2019


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 this past week:

Wednesday: Polar’s $199 Ignite GPS Hands-On: Everything you ever wanted to know
Friday: Testing In The Wind Tunnel with Stryd’s New Running Power Meter

I had three slated posts slide due to last minute tweaks from companies. So…you’ll likely see the fruit of those labors this week instead. Welcome to my world.

YouTube Videos This Past Week:

Here’s what hit the tubes over on the You of Tube, definitely don’t forget to subscribe there to get notified of videos the second they hit!

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 (and in this case, some of these are from the past few weeks…as my backlog is a bit longer):

1) Fundamental issues with recent Shimano based right-sided power meter: GPLama goes deep down the rabbit hole on this one with inconsistencies seen on newer Shimano-based power meters.

2) And a bit more detail from Keith Wakeham: And of course, Keith dives even deeper into the issues. Definitely worth a watch!

3) Apple Watches offered by Apple for grants: Apple will be launching an Apple Watch grant program, for organizations wanting to do research projects using Apple Watch. Of course, this is more of a formalization of something that already occurs. Apple has funded numerous research programs already with Apple Watches.

4) Apple Watch continues march towards no iOS dependence: This will allow Apple Watch to get updates directly from Apple without requiring connection to an iPhone. Of course, there’s still many other dependencies that need to evaporate (and apps that need to instantiate), but I wouldn’t be surprised if we see the next Apple Watch this fall (assuming a yearly cycle) include Android support.

5) The esports bubble is ready to pop: Of course it is. Duh.

6) Garmin announces sleep study results: Putting this on the pile of slightly older things, Garmin commissioned a sleep study, and these are the results.

7) Samsung Galaxy Watch Active v2 might include LTE: Or might not. Also, somewhat surprising to see rumors only a few months after the current device released. I’d be hesitant to put much stock in this. Often rumors are wrong or timelines horribly askew, be it for Samsung or Garmin. That said, as far as LTE support goes, Samsung is one of a couple companies globally that can pull this off at this price point, because they’ve got the telecoms by the round things. Leverage is a key requirement for succeeding today with cellular-enabled wearables.

8) Researchers develop AI for listening for cardiac arrest: Well that’s super cool. Basically the idea of taking an Alexa speaker or such, and having it listen for the breathing/gasping patterns of cardiac arrest. Whether or not someone can commercialize this successfully is a different question.

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 and a few other firmware updates.

Garmin Edge 530 Firmware Update: Bug fixes, and prioritization of ANT+ sensors over BLE sensors (to minimize issues/confusion)

Garmin Edge 830 Firmware Update: Bug fixes, and prioritization of ANT+ sensors over BLE sensors (to minimize issues/confusion)

Garmin Fenix 5 Plus Firmware Update: Bug fixes

Garmin FR245 BETA Firmware Update: Bug fix

Garmin Instinct BETA Firmware Update: Bug fixes and Explore improvements

Garmin MARQ Athlete Firmware Update: Some new features, pile of bug fixes

    Hey Ray,

    Not sure where to put this one so here it is – have you ever done (can you do) a post on how you manage uploads from multiple Garmin devices? And, whether there is a “better” file to keep or not?

    I have a 945 and an Edge 830 (had a 935 and an 800 before that) and when I’m riding I run both as backup just in case one crashes. However, that means I usually get both activities uploading to Garmin Connect, Strava and Training Peaks. I can delete the duplicates manually but that’s annoying and I’m also never sure whether to delete the 945 file or the 830 file (does either have more data etc.).

    Cheers for all you do!

      The Edge should give you more data. In my case (945 vs 530) I got MTB metrics, some advanced powermeter data, nutrition data (if you care about) extra only in the edge fit file. Also the temperature coming from the Edge should be better if you don’t use a Tempe.
      If this data moves on to third parties like TP is a whole different story.

    • MDus24

      Also the watch can only add and store data from 2 iq datafields while on the edge you can use 10, I think, which also gives you (theoretically) more data

    • Yeah, for me I just tend to keep all the duplicates on Garmin Connect, but then weed out the duplicates on Strava, and ideally also on TrainingPeaks when I remember.

      Unfortunately, it’s all manual. Like MDus24 said, in theory you’d want to keep the Edge data assuming all else equal.

    • ekutter

      I didn’t think Strava allowed for multiple uploads of the same activity. Meaning I thought it would fail if there is already an activity up there. Maybe it’s just the manual process that has this limit as I never have files automatically uploaded to Strava. And I’m with Ray for GC, just keep all the files there.

    • Nate C

      I use Garmin Connect as the “Truth” for my training logs (allows for editing of distance for occasional times when I forget to start the watch after a break on a known route), which I think is not available on Strava without creating new manual activities.

      By deleting duplicates, I can easily track total mileage by sport for any time period and for specific gear tagged to the activities (I.e. uploading two identical runs would attribute twice as much mileage to the default running shoes and I’d be replacing them twice as fast…). And if you use MyFitnessPal calorie integrations, your activity/sport calories aren’t doubled, and I think may also affect the TrueUp and training load metrics.

      To avoid duplicates, I usually upload from one device after pausing both at the end of an activity, and then discard the backup device without saving after I can see that the primary device uploaded successfully. (When comparing new devices, I will sometimes upload both to make sure they capture data similarly and then delete the duplicate…)

    Nice to see Garmin include some useful notes on their firmware updates. I have some friends that have been wondered if they should use BLE or ANT+ connections and Garmin gives concrete and simple guidance on this. Kudos from me.

    • Agree, I thought it was the most useful descriptor I’ve seen in a long time in their release notes. I mean, usually they’re pretty good about listing the core changes, but this was a super concise description.

      And also one I absolutely agree with. I always recommend using the ANT+ side of things over BLE, unless there’s some specific issue someone has. But that’s especially true for power meters because folks just won’t get all the (extra) data their power meter is sending over BLE.

    Still waiting for the 1030 firmware update to add the 530/830 features. ?

  4. Peter

    Also Wahoo has some new updates

    Apparently, a recent Garmin Connect for Android update broke the very useful gexporter/gimporter connection. The biggest news for me this week.

    FULGAZ does not matter until they push out to Windows. Great program but I only have troubles with BT. I have a year subscription but I have not been able to connect all my sensors….When they get ANT+ on Windows I am in for the long-term…

    Right now I only keep the subscription only for my wife on the ATV4.

    Clever Training advertised the Humon muscle oxygen sensor. Interesting sounding tech. Planning a review?
