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!

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

Thursday: Garmin Vector 3 Power Meter In-Depth Review
Sports Tech Deals of Note:
Despite what you might think – the sports tech deals are cruisin’ on! In fact, especially for Europe, which has seen the lowest prices ever for many items, much of which is still matching Black Friday sales. All of these are detailed on the massive deals post that I still keep updating.
Still, here’s the rundown of major deals still cookin’:
Wearables:
Product | Sale Price | Amazon | Sale Notes | |
---|---|---|---|---|
![]() | AmazFit T-Rex 3 - $40 off | $240 | Amazon | |
![]() | Apple AirPods 4 - $60 off! | $119 | Amazon | |
![]() | Apple Watch SE (2022/2nd gen) - $100 off $249/$299 (cellular) | $169 | Amazon | It's really hard to beat $169 for an Apple Watch. Again, like the other Apple units on this list, the SE3 was announce last month - which adds an Always-on Display, among other features. But at $169 with otherwise all the same software features as the higher-end Apple Watch units, this continues to be one of the best deals in smartwatches out there. |
![]() | Apple Watch Series 10 - $120 off $399/$499 (cellular) | $279 | Amazon | With the Series 11 out last month, you'll see sales on the Series 10. That said, there isn't a huge difference between Series 11 and Series 10. So if you were looking at the Apple Watch SE3, this might be worth grabbing instead for the added features. |
![]() | Apple Watch Ultra 2 Black Titanium - $150 off | $649 | Amazon | With the new Apple Watch Ultra 3 announced last month, it's time to clear some Ultra 2 inventory. This is pretty much the 'normal' sale price for the Ultra 2. |
![]() | Garmin Epix Pro - $250 off! $899/$999 | $499 | Amazon | ⚡ This is avery solid deal! The Epix Pro has the latest optical HR sensor in it, and thus has full ECG support as well. Note, this is for a 'renewed' model. In Garmin lingo, it means it went back to the (same) factory in Taiwan, and went back to the assembly line and is effectively a new watch again. I wouldn't have any concerned with a renewed model, but some might. |
![]() | Garmin Venu X1 - $100 off! | $699 | Amazon | This is the first time we've seen the Venu X1 on sale, since it came out this past summer. This is a good deal, though, I do wonder if it indicates the original pricing wasn't quite right here. |
![]() | Google Pixel Watch 3 (45mm) - $70 OFF | $229 | Amazon | The newer Pixel Watch 4 came out last month, and will start shipping this week. I see the Pixel Watch 4 as a pretty substantial hardware upgrade over the Pixel Watch 3, notably due to satellite SOS, as well as a user-replaceable battery. Still, this is a solid deal. |
![]() | Polar H10 Chest Strap (Dual ANT+/Bluetooth Smart) - $15 off $89 | $84 | Amazon | |
![]() | Polar Verity Sense - 15% off $99 | $82 | Amazon | I use this as one of my reference devices for heart rate accuracy testing. |
![]() | Samsung Galaxy Watch Ultra (2025) - $100 off! | $549 | Amazon | |
![]() | Samsung Galaxy Watch8 - $35 off | $314 | Amazon | |
![]() | Suunto Run - $50 off! $249 | $199 | Amazon | This is a very solid deal. It's got virtually all the software features of Suunto's higher-end watches (minus the app store), and just came out this past May. |
![]() | Suunto Vertical - $120 off! | $379 | Amazon | While the new Suunto Vertical 2 just came out last week, if you wanted to stock-up on MIP-based display watches before they disappear, here's your chance. |
![]() | Wahoo TRACKR Heart Rate Sensor - $15 off $89 | $84 | Amazon |
Cycling:
Product | Sale Price | Amazon | Sale Notes | |
---|---|---|---|---|
![]() | Garmin Edge 540 - $73 off | $267 | Amazon | ⚡At $267, it's pretty much impossible to beat this deal in terms of bike computers. There's no competitive option that beats it on features/battery/etc at this price, or frankly anywhere near it. Sure, it doesn't have a touchscreen, but it's not as bad as it used to be (I did a stint on it this winter for a week or so, and was fine). |
![]() | Garmin Varia Radar (RTL515) - $50 off | $149 | Amazon | This is Garmin's standalone radar+taillight option, and $149 is pretty much the standard sale-price. Even despite all the new radars out there, this remains the most accurate option on the market. Now, only if Garmin would just re-release it with USB-C. C'Mon Garmin... |
![]() | Wahoo ACE Cycling GPS - $90 off! $599 | $531 | Amazon | |
![]() | Wahoo BOLT V2 - $30 off $279 | $237 | Amazon | |
![]() | Wahoo ROAM V3 - $70 off! | $395 | Amazon | This is the first time we've seen the ROAM V3 on sale (notably the BOLT V3 is not on sale, though the larger ACE is). |
Action Cams & Drones:
Product | Sale Price | Amazon | Sale Notes | |
---|---|---|---|---|
![]() | DJI Mini 4K Drone - $60 off | $239 | Amazon | If you're looking to get into flying with a DJI drone, this is a solid place to start. Of course, moreso than that, the days are very limited for how much longer you can actually buy at DJI drone in the US. So, grab them while you can. |
![]() | DJI NEO - $30 off! | $159 | Amazon | This is the lowest price on this drone, and is a great option if you want a follow-me drone that's pretty hard to kill, at a price point that's still super reasonable. |
![]() | DJI OSMO 360 - $137 off | $412 | Amazon | NOTE: This is not sold by DJI directly via Amazon. DJI itself is NOT selling the OSMO 360 in the US, and WILL NOT support/repair it in the US. That said, it's a solid deal if you're ok with those risks. |
![]() | GoPro Hero 13 Black - $50 off | $349 | Amazon | |
![]() | GoPro Hero 13 Black Bundle (extra battery/SD card/floaty) - $100 off! | $379 | Amazon | ⚡ This is a very solid deal. It's a Hero 13 Black on discount, but then an extra battery tossed in, then an SD card, and then a floaty. |
![]() | GoPro Hero 4K - $20 off | $199 | Amazon | While the new Hero Lit was announced a few weeks back, which includes a front LED light, for the most part it's the same camera inside. Note I'll have a full comparison shortly though between the GoPro Hero Lit, DJI OSMO Nano, and Insta360 Go Ultra. |
![]() | Insta360 X5 360* Action Cam - $50 off! | $499 | Amazon |

YouTube Videos I Made This 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) The most incredible bike share photo: This photo shows what happens when you fill an entire football field with discarded bike share bikes…and stack it as high as some buildings. Unbelievable, you really need to see this photo.
2) Jumping into an airplane with a wingsuit: Undoubtedly, many of you have seen this by now. But if not, enjoy. And if you have already, enjoy it again. It’s worth it, as you know.

3) Getting the GoPro Shot (further details): Last week I shared a GoPro video on the behind the scenes of just one brief sequence in the launch video. This post however details that out even further in a more textual manner.
4) SoulCycle now offered as benefit on a points credit card: For those in Europe, the whole credit card points thing is illogical. But for those in the US/Canada, you know it’s all about the points card. This card apparently offers free days at SoulCycle. I thought it was interesting (I’ve never done SoulCylce however).
5) Fitbit selected for long-term national health study: Regardless of which vendor is selected, it’s good to see some long-term studies being done with vast numbers of people. Let’s just hope that there’s at least a few people that understand technology helping with this study, so that we don’t end up with all the flawed ones we see recently on wearables.
6) GlovePay, it’s a thing: Forget Garmin Pay and Fitbit Pay, for the upcoming winter Olympics, you’ll be able to pay by rubbing your gloves against the payment terminal.
7) FDA approves first EKG reader for Apple Watch: This is an interesting one, but one you shouldn’t be misled by the main headlines about it. This is NOT the FDA approving the Apple Watch as an EKG reader. Instead, it’s the FDA approving an accessory for the Apple Watch by a 3rd party company as an EKG reader. The cool part here though is that it’s doing it via an Apple Watch band/strap that you then place your finger on. I’ve gotta believe the company will look to make straps for other devices like Fitbit and Garmin, since it’d be easy for them to leverage app platforms on both companies devices.
8) Study looking at accuracy of the CycleOps Hammer trainer: Not too shabby. Though personally I would have liked to have seen wattages above 500w, since that’s pretty low by most testing standards. (via Tim)
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 Edge 520 and 820 Firmware Updates: Adds latest Connect IQ support, tweaks some indoor trainer stuff, other fixes. (both units identical here on update)
Garmin Edge 1000 Firmware Update: Adds latest Connect IQ support.
Garmin Edge 1030 Firmware Update: Adds latest Connect IQ support, boatload of other tweaks and some new features.
Garmin Fenix Chronos BETA firmware update: Bunch of fixes/tweaks.
Garmin Forerunner 735XT Firmware Update: Adds latest Connect IQ support, some Varia Vision tweaks.
Garmin VIRB 360 Firmware Update: Apparently resolves random things that were too random to list.
Wahoo ELEMNT/ELEMNT BOLT Firmware Update: Mostly bug fixes, but a smattering of new features including zero averaging calculations. GPLama also did a more detailed piece on it here.
Zwift update: You can now control the camera with far more granularity, allowing you to rotate it around you like drone shots. Also a pile of other new features and stuff, but the camera one stood out to me as nifty.

With that, thanks for reading!
$349 for the PowerTap C1 chainring power meter is an amazing deal. I just purchased – upgrading from left-only Stages. Thanks Ray!
I just recently found out about the Apple Heart Study. I’ve installed the app on phone and watch and signed up but nothing has happened yet. I don’t know yet whether they’re going to take data from anyone who signs up or only a selected few. Looks like it’s being paid for by Apple and run by Stanford.
What a shame that the Chinese government is just creating a giant scrap pile of bikes, rather than stuffing them in to containers and sending them somewhere that could really benefit from them through something like link to worldbicyclerelief.org. I’m sure that the vast majority of those bikes could be repaired by cannibalising parts from other bikes, at least before the were heaped up so high, which has likely bent anything more than a few feet deep beyond rescuing.
Indeed, that was both my and The Girl’s first thought as well. Just thinking that WBR could likely whack the bike locks off of these and call it macaroni.
Of course, it’s far more complex that that – but certainly some org must be able to use these in rural locales.
Here in Hong Kong I first thought that bike sharing was a good thing until it became obvious that many users are just too irresponsible and just leave the bike where they need to get off. That is in the middle of the walking/running path, in front of stairs or anywhere else they get in the way of other cyclists and pedestrians. The bike share companies are not much better, pushing out their bikes in public bike parking to the extent where there is no spot free for people to park their private bikes. Setting aside the fact that its a waste to just discard them, I would not mind if I saw a pile like the one of the pic here in Hong Kong.
I do remember a similar but smaller pile on a pic form Beijing, It was outside a hospital and it was bikes left by incoming patients that had to be piled up so they didn’t block access to the hospital.
The Hammer study summery says they are comparing to a “scientific SRM system” while the full text says its Powertap P1 pedals. Gee, I wonder who funded this…..
“The last 45s of each measurement was analyzed.”
Doesn’t a persons power output get steadier towards the end of a 3 min interval so easier to measure? Seems like steady state was accurate but the sprint test wasn’t so good based on figure 1.B
For those who want the full text: link to fredericgrappe.com
Nice find, I couldn’t find it quickly. That is odd.
What’s funny is that in looking at the authors of the study with their affiliations listed in the full text, I know from some other things just being local they work very closely with PowerTap/CycleOps on other projects. Didn’t recognize the author names, but definitely the orgs. Good call…
The comment on the dual sided WatTeam power meter says:
⚡⚡THIS BRINGS IT DOWN TO 300GBP/342EUR FOR A SINGLE SIDED UNIT – BY FAR THE CHEAPEST DIRECT FORCE POWER METER OUT THERE.
It’s £300 for a dual one or £204 for single (as you say in the next line down).
And the DCR discount applies too, so it’s even cheaper! :)
Hello Ray
Tourism Flanders has created a website ‘Cycling in Flanders’ to promote its cobblestones classics to foreign cycling tourists: cool!

I think you have discussed this before but I can’t find it — do we know how long for tomtom have committed to supporting their web platform?
I’ve commented on the wrong post ?
