- The old Stryd footpod vs the newer Stryd Wind footpod for pace and distance at Worthing Track.
The idea was to run 10k round the track. That's 25 laps of a 400m track and see how close the footpods could get to the correct distance.
Here is a similar test on a 10k straight course on the seafront promenade near my home. • Stryd Footpod Testing ...

Great conclusion;) thanks!
Roughly 1% margin of error either way, that's really good if you ask me! Especially uncalibrated and I guess what would effectively be like 'out of the box'. Plus with the positioning of them I'd argue the margin is even closer than that... Pretty darn impressive!
Agree. I think anything under 2% is probably fine.
I find with every pair of trainers I need to recalibrate....
Nike Zoom Fly 97.9%
Kinvara 11 98.2%
Pegasus 36 100.9%
Endorphin Speed 99.9%
As long as I remember to switch the calibration value before a run the stats are very accurate, if I forget the stats can be waaay off 🙄
While Stryd claim it's impossible, it's a known problem by anyone who's bothered to do any detailed testing, but worse it can change from one run to the other by +/- 2% and pace has an influence too.
@@Peakabike That is exacting what I find. Same shoe, same calibration factor, same placement on shoe, same pace...for me does not always give the same distance.
Very good video, i always do a calibration test at the start of the season, mine came at 100.5, very accurate footpods in any case
I agree. Whilst these results may not be perfect, I think they are very good with less than 2% error without calibration.
I have wheel envy! Which one is it? With my Stryd Wind I found a calibration around 102.5% was about right. In other words my Stryd "uncalibrated" reads a bit short. So interesting you found the opposite. I have tried 3 of the older non Stryd wind ones and one needed a calibration under 100% (so it read "long") and the other two bit over 100% but less than my Stryd Wind. Each is however then fairly consistent to itself. I did my own video on the Garmin Track Run app and if you are running on a track and have a suitable device that is the way forward I think and especially good for races where, as you mentioned, the distance is what the race is not what your device might say. Might be interesting to see what distance you got from GPS if it was in "normal" mode. Generally for me GPS gives a good enough distance and I don't use a Stryd for that. It is after marketed as a power meter not a measuring device. Good to know once again though that the Worthing 400m track is indeed 400m! I can't recall a UK ever having to be "rebuilt" as they built it to the wrong size.
Really great real world review. Unfortunately, they are still way outside my price range.
Unfortunately Stryd is not accurate. Depends on shoes, style of running etc. I always have to calibrate before races for the specific shoe to get it right. Dont know why nobody is talking about it, great video!
Great video, what you haven't tested for though is the variability from one run to the other, redo the same test 7 days later with the same shoes and be ready to see a different result, within +/-2% based on my experience. You'll see changes with a different pace too.
Thanks. Yes, I’ve been using the Stryd for many years now and I have done these tests many times. I just haven’t filled them all!! I do plan another video testing the same thing but in a straight line.
@@FilmMyRun Sounds good, on a shorter distance then ? If you get a chance it would still be great if you could redo the same long 10k test at a different time as that limits the risks of "errors" due to when the lap button is pressed. I've seen people complain about errors when timing 400 meter laps and Stryd rightly advise to run 8 laps I think before drawing any conclusions.
Did you ever notice variances over your years of using Stryd ? It's really not something one expects to experiment based on the advertising done by Stryd where they claim perfectly consistent results. Like most I was happy to take that at face value until I started to see these +/-2% shifts on new officially measured 1k segments on my usual route. It's hard to find people to discuss them with as Stryd censors these discussions on their FB page but sometimes some slip through and that's where you find that people who've looked into this seriously do indeed see these unexplained shifts.
@@Peakabike I’ll be doing a full 10k with the measuring wheel. 5k out and back. I’ve had four Stryds going back to the Stryd Pioneer chest strap. All of them have given differing power and distance results. Although usually they are fairly consistent with themselves.
Geat Video!
What happens if you set the wind footpod to calibration 102 and then run 10000 meters?
Calibrating your Stryd will most definitely improve its ‘accuracy’.
will you consider doing a test on hilly course, would be interesting to see if it accurate or as accurate
It’s not accurate. I run all the time on hilly terrain with the Stryd. The old Stryd is better than the Stryd Wind, but both will need a calibration factor applied.
Useful test and thanks for posting this video.
Distance deference between right and left foot should sum up to about 30m at 10k and 1,2m per lap (assuming 20cm offset).
Your logic was inverted. "Wind" was inside so it should show too small distance at 10k mark and it did , you had to run another 170m (instead of only15m more). Old one was on outside so it should show too big distance at 10k mark and it did.
I think less than 2% accuracy is pretty good for inertia based measurement. Wind was 6,8m off per lap (6,2m taking into account different radius of the arc), and old one was 3,6m (3m). Your another measuring wheel was 1,6m off per lap. It sum up to 40 m at 10k.
I just got a Stryd to use with my Apple Watch series 5 and I've found that, on running a 8.5km route I'd previously ran before, it was under reporting distance and pace by about 4%. On previous runs I've found that the distance reported by my Apple Watch (using the workout doors app) almost always matches the corrected GPS distance in Strava. Would be nice if Stryd had a calibration option that could be done a flat straight open outdoor area using GPS. I know that the Apple Watch uses it internal pedometer to compute distance but that is also calibrated initially using GPS data.
can you provide info on the measuring wheel, i may want to buy one, thanks.
Of course. I have this one Digital Distance Measuring Wheel... www.amazon.co.uk/dp/B07NJHVBQ1?ref=ppx_pop_mob_ap_share
@@FilmMyRun thanks, i guess they cant ship to me in usa, do you have an alternative or how i can find an accurate one like yours, and thanks for quick response, i dont like my fitbit ionic to give me good measurement
@@BayAreaMusicLens just search for a 318mm measuring wheel on Amazon.
@@FilmMyRun thanks for the help, of course many of our tracks are 440 yrds but i guess in can convert 1mi to meters
How about the power readings for each Stryd?
I was not testing this today. The test was focussing only on distance.
@@FilmMyRun the conclusions of your test is that it's more accurate to count laps than use a watch if your track is measured correctly
@@sylvainbauge hahaha I guess you could look at it that way! If you are racing on a track, it matters not how far you have run at all. The finish line is at the finish line on the track. If it’s a 10000m race, you might have actually run 10080m but the results will not give you that extra 80 metres. It’ll just say you ran 10000m.
My testing was to see how accurate the Stryd Footpods are at measuring distance uncalibrated.
@@FilmMyRun true but if you're running by yourself you can lose track of the lap count 😂
@@sylvainbauge This is indeed true!
As far as I have read and viewed almost anywhere re the Stryd, it is said to ALWAYS calibrate the Stryd. There might be a reason for it.... :)
I think the advice from Stryd themselves is precisely the opposite to be honest. They would say that calibrating will make the Footpod less accurate. But it’s true that everyone Stryd I have ever owned needs calibrating.

@@FilmMyRun Calibration has no impact on the footpod itself, only on the pace/distance the watch reports. However the problems arise when that calibration "shifts" between shoes and/or runs and/or pace by around +/- 2% because pace is used internally to calculate power. Say your CP is done with a Cal98 shoe and you race with a Cal102, shoe it's going to be impossible to hit your target in a 10k...I've been there and it's...distracting.
@@Peakabike Exactly, I am loosing lots of power on my stryd profile because I have some "slower" shoes according to stryd :(
Most shocking thing about this video is that you've got 2,772km on that pair of shoes.
Haha I know. Although that distance is spread across two pairs but nevertheless it’s just ridiculous.
What do you mean?
@@maharajaasura Strava allows you to track shoe usage and it showed an insanely large number.
Wouldn't this have been a better test had you calibrated both Stryd pods first? All I see your test showing is that un-calibrated pods give un-precise results.
Yes which is precisely my point given that the website states ‘accurate out of the box’ and many many Stryd users automatically assume their pod is 100% accurate and continually repeat this ‘fact’ on all their FB groups! But this is actually an old test. We’ve now shown the Stryd is not even accurate once it’s calibrated as it will change distance measured simply from different stride lengths.
@@FilmMyRun Thanks for filling me in. I was considering buying a Stryd for its pace/distance accuracy since using GPS for that purpose is so inconsistent. Now I am reconsidering that thought...so thank you for helping enlighten me on Stryd. It is hard to beat pace derived from know distance marks using a stop watch. However, I do like a GPS watch for giving me distance and ballpark pace.
@@stevebailey1682 if you get a newer watch it will have much improved multi band GNSS which is more accurate than previous GPS watches. In my opinion Stryd is a running power meter and is very good at that. It’s not fit for purpose as a distance measuring device for runners.
@@FilmMyRun Good to know to look for multi band GPS. I do have an older watch and although it does have 2 bands (GPS & GLONASS)...using both I have seen no real difference in accuracy. But I do see there are watches now with more than two 'bands' so will look more into those. Thanks again.
Hey Stephan. I am circling back on this topic as I now have a Stryd pod (I bought used) for my own testing purposes. I have calibrated my unit both on a 400 meter track and a couple of courses I have measured with a calibrated bike wheel. What I find is about a ~2% variation in distance using the same shoes and same pod location on shoes. Pace does appear to effect the consistency. This is disappointing. Given Stryd power is a function of pace which itself is a function of distance and time, power will be inconsistent too...but maybe not to the 2% level. One final question then for you...since you own a couple of multiband GPS watches...do you find distance for those watches to be more consistent than from a Stryd pod?
