Garmin Running Power vs Stryd
I was reflecting on the information that has emerged over the last week or so on Garmin’s impending foray into Running With Power. I got around to writing a few initial comments yesterday (link to: the5krunner.com) and I also draw your attention to STRYD’s blog post from Monday (linked to and duplicated, below).
The specific information that Garmin was going down this route was known to STRYD last week at the ANT+ Symposium.
Like others (dcrainmaker) I had been expecting a premium power pod of some sort from Garmin. Something like STRYD’s pod but different AND, certainly, more expensive ;-). On reflection, I suppose the introduction of the clip on RD pod was an early indication that a new, dedicated power footpod probably was not in the offing. No one was expecting a freebie.
You pay for what you get.
On further reflection Garmin’s move is cleverer that I first thought. Maybe it is some sort of internal app development exercise (DCR) but maybe it is a quick, low-cost, low-resource way to increase sales of high-end, Garmin product? Let me explain. I quite happily use a Garmin 235 and STRYD. It works perfectly well. But for a Garmin 235 owner interested in running with power for the first time and PERHAPS also contemplating an upgrade to the upcoming Forerunner 245/645 (which will likely be announced at a similar time as the Garmin Running Power stuff gets more formally rolled out). Then PERHAPS the temptation of free power will tip the balance in favour of an upgrade. Kerching £$£$£
Maybe also a new pod from Garmin would consume too many internal and post-sales people resources for what is, after all, a relatively small end market?
Then, after more reflection, I became a little less optimistic about Garmin Running Power. My excitement has waned and grumpiness has returned. (I need some running endorphins).
- STRYD’s numbers feel right to me. The ups and downs DO seem to be a proxy for effort of some form or other. Whether 200w or 400w is ‘correct’, I have no idea. BUT the ups and downs feel right. Garmin and RunScribe need to convince me that their ups and downs are similar. I have a plan 😉
- It also feels ‘right’ to a few triathletes I have heard from, that running FTP from STRYD and cycling FTP are similar. You can add me to the list of those people as I train roughly equally between running and cycling. Of course ‘feel’ is not a science…yet.
- It seems that STRYD has studies that correlate their data to VO2. That sounds a bit more sciencey. There might be some indoor nuance to what they have done already and that might be why their blog post from today/yesterday (link to: stryd.com) makes the specific point of showing them testing VO2 outdoors.
- My understanding is that pace is an input to the STRYD power model. Apparently, Garmin’s power figure partly comes from a GPS-derived pace. My repeated experience is that Garmin sports watches’ GPS performance is demonstrably below that of Polar and Suunto (link to: the5krunner.com). A question would be “might this partly explain the 100w differences dcrainmaker found in his first run?”. Especially as part of his run was through trees and up a mountain. Trees and mountains are not great for GPS, in my experience. Probably yours too 😉
- Perhaps Garmin’s model might be improved by a better source of horizontal speed? Perhaps they could use STRYD for that purpose 😉
- Many people are super-happy with the accuracy of STRYD for pace (me included). Fellrnr’s chart is included below.
- Garmin Running Power proposes to use the clip-on RD pod. If you recall STRYD’s gen 1 product was a clip-on. STRYD abandoned that route for a reason. It didn’t work. It didn’t work because of changes to the elasticity of the waist garment and muscle-related factors. eg a big meal might equal a tighter waist and more power 😉 Gen 2 was the chest strap and Gen 3 the footpod.
- If you are a cyclist and have not yet used power for running then you wouldn’t be aware that your running ZONES are much narrower than cycling ones. So a 10w error when running can easily throw you way out of a zone. ie wrong training…put bluntly.
- I’m not quite sure how Garmin’s solution will work on the winter treadmills of North America. STRYD’s does work on treadmills.
So then I wonder if Garmin have made half a mistake?
Probably not. Garmin Running Power data is going to be ‘quite nice’. And it’s going to get some (many) people using it who would never previously have entertained the notion of running with power. However I suspect it will have limitations that feed through to INaccuracy in certain scenarios (as indicated above). That won’t bother many runners. But it MIGHT bother the more tech-savvy runners. The tech-savvy runners who buy higher-end Garmin watches. The watches that this tech works on. hmmm. ie the people who buy STRYD anyway. hmmm x2.
Here’s what’s going to happen, in my opinion:
- Some STRYD purchases will be delayed by this news
- It (Garmin RP) will be released in Novemberish
- It will be working but with data discrepancies in Q1-Q2.2018
- RunScribe Plus will hit the streets soon. THAT will be the proper initial competition for stryd for people serious about running power in 2017 (what’s left of it).
- The ANT+ standard will be sorted out for running power by Q1.2018 and then within 6 months for BLE. Hopefully by the end of the year the data standards will be in a good place. (Edit: Q3.2019…ahem)
- The Garmin announcement will drive innovation and maybe price changes for both RunScribe and STRYD who might initially be nervous about the Garmin offering.
- Do you really think STRYD and RunScribe didn’t see anything coming a year ago from Garmin? (Hint: they did…watch this space)
- 2018 through 2019 will see LOTS more people dabbling with power because of Garmin’s welcomed innovation.
Here’s a suggestion: Dear Mr Fitbit, perhaps your sporting battery life could be improved? Customers seem to want that. Perhaps you could use STRYD as an accurate source of pace for your sporting apps and intelligently turn off GPS more frequently depending on the degree to which the app needs navigation and post-run location/mapping info.GPS is a big drain on the battery, I believe. Just a thought.
That’s a big market. If you think about it and read between the lines quite a bit.

Stryd is the ultimate racing experience.
There is a tried and true method to have the ultimate racing experience. The secret? Power. We have carefully designed and refined Stryd to give the best power available on the market.
Your race experience will only be as good as your power. Find out why.
Zone in: Run with the correct power
Why is your performance top notch? It is because our power is top notch. It is highly important to have a precise, accurate power number so you can recover properly and stay in the proper zone during training. When your power is consistent, you train the right systems of your body. When your power number is precise, you know the exact amount of recovery you need to prevent injury.
Stryd measures your performance via metabolic costs. If the power measurements do not match Stryd, they are simply not measuring metabolic costs! Our technology has been verified as accurate and consistent through university and laboratory studies. Read more here.
It is a game of seconds: Run with precision
Stryd offers best-in-class speed and distance measurements straight from the box. We adapt to your unique running form from the moment you go from your first run. This highly accurate speed factors in to your power number. You will always stick to the race plan because Stryd is the perfect guide.
GPS watches with power? They will not cut it. GPS satellites are over ten thousand miles away. They give slow responsiveness which means your race plan suffers. You need a STRYD on your shoe to measure your power in real time. It responds quickly and brings great reliability. It is the only way!
Care for your legs: Measure your leg stiffness
Want to run more efficiently? Look at your leg stiffness. We put Stryd right on the foot to measure your leg stiffness. Your legs are your most important tool on race day so you should to give them the proper attention. Measure how strong they are and improve over time!
Run everywhere: All terrains, weather, and conditions
Where will you run? Will it be deep in the mountains on a snowy day? Will it be in the heat of the desert on the flattest terrain on Earth? Stryd is ready to take you there. We collected billions of strides across the world and dissected them. Stryd has seen it all.
We are ready to take you everywhere: from the smoothest treadmill to the toughest trail. Be prepared for anything with Stryd.
- You get precision from Stryd’s highly accurate speed and distance.
- You become a more efficient runner from Stryd’s leg stiffness metric.
- You can confidently run anywhere with Stryd’s billions of world-wide data points.
