Week in Review–April 21st, 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:

Tuesday: 5 Random Things I Did This Weekend (Sea Otter Edition)
Wednesday: Sea Otter Sports Tech Update: 4iiii, Acer/Xplova, Barfly, Bryton, K-Edge, Stages, Wahoo
Thursday: TrainerRoad Opens Up New Outside Workouts Feature, Outlines Bike Computer Integration

Hold onto your saddles folks, it’s gonna get crazy here momentarily.

Sports Tech Deals This Week:

There’s still a pile of deals out, most of them ending in the next week or so:

Garmin Edge 820 is down to $259, a pretty massive price drop. My full post on the unit here.


Garmin Vector 3 is $100 off, and Vector 3S is $50 off My full in-depth review on them here.


GoPro Hero 7 Black is $50 off (not sure when that ends). My full review on it here. It’s what I use on every ride/run I do. Note the unit from Clever Training comes with a free 32GB MicroSD card.


Fitbit Alta HR is $40 off, down to $89 – This model is being replaced by latest units, but it’s frankly still a fantastic unit for the price to have optical HR in it. Full review here.


Fitbit Ace Kids activity tracker is 11% off, this is the first gen ones though. Still, I suppose if you’re in the Fitbit ecosystem already.

All of these help support the site as well – enjoy!

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.

1) Zwift adds new desert time-trial like course: It’s not too shabby. I had a chance to ride it last week at Zwift HQ prior to release. I know a lot of folks have been asking for a flat course – and this certainly delivers. Also, on a well equipped (graphics-wise) machine, it really shines. Here’s Shane’s overview video on it:

2) AI creates a new sport: It actually doesn’t sound half-bad. Given all the crazy-ass sports that we as humans have come up with over the years, this seems quite normal.

3) Kickstarter to trial ‘guaranteed delivery’ campaigns: The backer would get their money back if the product doesn’t ship. Meanwhile, the company doesn’t get their money until the product ships. In unrelated news, the rest of the world calls that concept ‘a store’.

4) The logistics of getting Astronaut Scott Kelly’s blood back to earth: While having almost nothing to do with endurance sports, I found this pretty fascinating (also, if you remember back to my very first ‘Week in Review’, it was never bounded by sport-specific stuff)

5) Withings restores Pulse Wave Velocity to weight scales: You’ll remember this feature was included when the scales launched a few years ago, but was pulled a short bit later due to concerns around validity. Now it’s back.

6) Polar releases firmware adding ANT+ to H10: While normally this falls into the firmware updates sections below – it’s kinda a big deal. I talk about it here in this post when they first announced it. But now you can actually update your own units (for free, just takes a couple minutes). Now…where’s that Vantage ANT+ update? [Update: OH1 firmware not yet out yet]

7) Wanna buy a wind tunnel? No problem, now you can. You’ll likely lose a tremendous amount of money – but hey, when did that ever stop most triathletes? 😉

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 Fenix 5 Plus Series BETA Firmware Update: Bug fixes

Garmin Forerunner 645/645 Music BETA Firmware Update: Mostly music focused updates, including adding mono/stereo music playback

    I always enjoy looking through the things you found interesting section of the post, you always have an article or two that makes me curious.

  2. Jim

    So Edge 520 plus or 820?

  3. Marcin

    I can’t find this new odometer from Wahoo – where is it?

  4. British Reader

    Edge 520 Plus at £199 on Amazon UK. Edge 820 at £171.10.

    why can’t garmin make a decent HR monitor, Whaoo makes a great one, never fails me. Just ranting.

    • GLT

      I’m one of the tiny minority that has never had issues with any Garmin, or any other brand HRM. Garmin HRM-TRI primary dedicated to my outdoor rides and a Wahoo TICKR X for indoor training & backup. Both seem to work equally great for me with Garmin head units. No irritation, drop outs, or disintegrations.

      Maybe there are some subtle issues with body chemistry or anatomy at play. Prior forum threads mentioned the frequency & workflows for washing HRMs after use. At best all I’ve ever done was rise them off once a month during the summer months.

    • Raul V.

      No problems for me either >> Reason 1: people with problems publish! Rest doesn’t. 2: average Joe makes mistakes. Like thinking sporting should result in sweating. (there’s people wearing shirts on a stationary!!!) Logical thinking will learn that’s an emergency action of the body.

  6. Bikeman

    Still no update on the OH1. I’ve pulled it out of mothballs to check. Back to the junk drawer.

  7. Brian Bossler

    I’ve noticed that scheduled TrainingPeaks workouts are now syncing to Zwift in custom workouts. Not sure if that’s new but it was new to me. ?

  8. Pavel Kajaba

    Beta update for FR645 lost support for galileo ?

  9. JP. Shorts

    Hey Ray
    Are there any cycling trackers out there that offer live tracking WITHOUT the need to have mobile connected?
    Ideally not a watch – either a small device in Jersey pocket or saddle bag, or really ideal built into GPS computer (like wahoo/garmin)

    This is mostly for safety and family tracking, but also when doing multi-day bike packing advertures.

    I’ve tried the Spot adventure trackers but not been impressed at all
    These just show location, but not speed, distance, elevation etc etc

    Thanks so much

    PS. Happy belated Easter

    • Paul

      Can you do this with an Apple watch with the virtual sim?

    • JP. Shorts

      Great suggestion Paul
      Ideally I’d like to not have to wear a watch as prefer cycling without watch/jewellery on etc
      May be my only option for reliably tracking without needing a phone in the Jersey pocket


  10. Thanks to your blog and website, over 3 years ago, I found out about WahooFitness providing gear which would supply data (e.g. heart rate and cadence) by Bluetooth connection to my phone in a generic format (.csv) which I could use as I wished. I bought their products and used their apps.

    Fast forward three and a half years. I go to use the app and find out it has been changed and the generic format option eliminated. Customer service told me there were many complaints. Does anyone know more about this? Does anyone know anyone else supplying generically formatted data?

    Polar OH1 Ant1 Update is out now too (well, since last Tuesday)!
