Week in Review–May 7th, 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–April 30th, 2017
Monday: 5 Random Things I Did This Weekend in Southern California
Monday: Huge Spring Sale: 20% of all trainers, all power meters, and plenty more
Tuesday: Hands-on: Hammerhead’s new Karoo GPS Bike Computer
Thursday: Wind Tunnel Time: Is the Wahoo ELEMNT BOLT actually the fastest bike computer?

Don’t forget the big 20% off sale (trainers, power meters and more!)

In case you missed it earlier this week, it ends on Wednesday, and will likely be the last solid sale you’ll see on big ticket items till November, especially this diversity of trainers and power meters.  Here’s a list of the most interesting ones to me – remember, everything below is then 20% off those prices. Details in the post:

YouTube Videos I Published!

Here’s some YouTube goodness that I published this past week, don’t forget to subscribe!


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) Pricing your sports tech product as a startup: There’s few people better than Keith to talk about this, and everything he’s written in this post is worth reading (even if you’re just a consumer and want to understand why things cost the way they do).  Keith was a driving force behind the 4iiii power meter, after his DIY power meter project.

2) These mice run marathons without training: See, there’s hope for the rest of us. Albeit, with drugs. But that never stopped Tour de France winners…

3) Cycling Maven conquers Kickstarter, vlogging grand tours: In case you didn’t see this – pretty cool stuff to see them do so well on Kickstarter and now rocking some great videos already (daily vlogging the tour).  I haven’t historically watched Mark and Hannah’s stuff religiously, but have been hooked since they started their trip.  You can also check out their Kickstarter here, and an interview Shane Miller did with them here leading up to it.  Below is today’s VLOG from yesterday at the Giro (daily vlogs are typically posted the following day, since it incorporates the full previous day):

4) Ikea makes bikes…here’s how it rides: Go figure. But I agree – any place I can get meatballs and bikes in one stop is a winner in my book.

5) Strava Live Segments…for Zwift?!? I haven’t tried this yet myself (just landed a couple hours ago back home), but looks pretty intriguing.

6) How Leadout Trains Work: Putting this in the category of ‘the more you know’.

7) Sport Scientists take on the Nike Breaking-2 Hour Project: If you’re going to read one opinion…this is the one to read.

8) Summit Training Kickstarter: This training app aims to automate more of the coaching side of things with their training platform.

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 Chronos/Fenix 5/5S/5X BETA Firmware Versions: Some new features, mostly bug fixes.

Garmin Edge 820/820 Explore/1000 Firmware Update: Bike light support tweaks/improvements, some bug fixes.

Garmin Vivosmart 3 Firmware Update: Improvements in optical HR, rep counting, Move IQ, and a few others.

Garmin Vivoactive HR Firmware Update: Minor bug fix.

Garmin Forerunner 920XT Firmware Update: Bug fixes mostly.

Garmin Forerunner 230/235/630 BETA Firmware Update: Bug fixes mostly.

    Hey Ray,

    Typo alert on the 920xt firmware notice: “Big fixes mostly”

    Is it a Bug fix or Big Fix? or a Big Bug Fix?

    Sorry for being that guy….

  2. Tosin M. Akinmusuru

    Did you watch the Breaking 2 attempt yesterday? They was an epic effort!

    • I was travelling unfortunately, but, it’s on my to-do list. Still, been keeping up with it. I linked to one piece I thought was well written on it (above), from those whose opinion I think matters most on it. Enjoy!

    Hi Ray,

    Speaking of VIP sales, I came across the Recon Jet glasses for 140€. That’s a low enough price to get in my impulse buy territory but I was wondering whether it was still a reasonable purchase.

    Did you manage to test the VIRB integration and do you know if the glasses are waterproof?

  4. Yonah

    Polar is having a 20% off sale on their site for mother’s day as well, but I think that it’s newest devices are excluded (M430, M460,M600)

  5. Grant

    “Fitbit Blaze – Save $149 (Amazon/Clever Training)”
    Should be save $50

    if you like No 6 you should watch Eurosport Science of Cycling on the sprint:

  7. Hi,

    I’m Jakob from summit training (#8).
    As we have just reached the first prototype stage we’d really appreciate any feedback to better focus our future efforts.

    You can contact me here or leave a comment on bikeradar forums (link to bikeradar.com). We’re also setting up a blog to share more insights into our app and methods we use. And thanks for your support!

    Actually this is IKEA’s second bike – they brought out a 20″ wheeled folder a few years ago, built by Raleigh

  9. For IKEA bike, do I have to assemble it myself? I feel like it will fall apart like everything else.

  10. Alberto

    Is it my idea or the FR 235 is a Beta firmware?

  11. Eli

    I noticed an additional feature added to the Fenix 5 beta firmware didn’t make the final 935 3.30 firmware that just came out:
    Added support for a new app, ‘Boating’.
    link to www8.garmin.com

    I’m not saying I care about boating, but is an indicator of the 935 not keeping up with the functionality that will come to the F5. Ray, do you know if this was their intention to leave the functionality off?

    • I don’t know of any intentions, but I would note that generally speaking the Forerunner team lags behind the Fenix team when it comes to this stuff. While they operate from the same general codebase, they have different testing and release schedules.

    • Dom

      I was wondering the same thing, but apparently it is actually there. To quote a Garmin mod on the 935 forum,
      It is not called out in the change log, but Boating is on the Foreurnner 935 in version 3.30

    • Eli

      Maybe my pessimism on the 935 will be proved wrong :) This will be my 10th Garmin GPS
