If you do not have the garmin power turned off the risk is that athletica will use that power data instead of the one coming from stryd. So, to be sure, keep it off.
If you turn it off, and you have stryd paired, the power data are registerd inside a proper garmin IQ field. Athletica seems to do not properly recognise that field and hence you won’t see any stryd data in your garmin imported fit file. Proably because the IQ field is either not well managed or totally ignored.
Anyway it seems that athletica can properly recognise power data coming from Strava. Hence the quick fix is exporting garmin .fit file to strava (using the strava athletica connection) that will also import it back as a strava .fit file. Merging the data from gamin fit file and strava fit file will do the trick.
It’s just a workaround but it will do.
A better solution will be to let athletica extracting the stryd IQ data field form garmin fit file directly
This is kind of along the lines that I figured was happening. I DO have Garmin power turned off on the watch and the Garmin Stryd field active on all my runs. In the Garmin Connect app it recognizes Stryd as the primary power metric. I figured most here can see the older 2023 and 2024 stryd data in Athletica because they were using the Strava connection, which properly showed the Stryd data over the Garmin power data. In 2025 we all unplugged Strava from Athletica after their API warning. That means we’re using Garmin as our primary connection now in 2025, but for some reason Athletica isn’t picking up the connect IQ power field data. I have to believe it’s there in the connected file though.
@Prof following up on this issue several users have reported here, not having power displayed on Athletica with runs synced from Garmin, while the same garmin files are displayed with power on other platforms such as Intervals, Strava or Training Peaks.
As reported by @thekappe loading same fit file into a new profile works. I have also tried creating a new profile, synced to the same Garmin account and I can see my running power curve built with over 28 runs this year. I can also see on that new account the curve from 2024 and 2023 are built on stryd power (no crazy numbers) while on my normal account garmin power was activated and retrieved by Athletica to build the curve
I would suspect something is wrong with our accounts while Athletica has previously loaded power from Garmin power as that was also reported by the other users impacted.
It may be that Athletica is looking for the IQ power field from the older Stryd IQ app. It will have a different ID in the fit file for the newer field. The newer one is Zones.
That’s so weird. I can confirm I also see this same behavior. I also get the same result if I download the FIT file from Garmin Connect and import it manually.
My athletica zones are still not correct. This maybe due to Garmin recording power once or twice which is about 100 higher than Stryd. Any way to manually adjust zones. They are useless now so I switched back to pace.
I’m not running these days but trying to understand more how we might do better for seamless running power guidance. Obviously we’re close but not quite spot on. After watching Dr Will I almost wonder if connecting with Stryd API might be the way to go. Any thoughts?
Good Day,
Quick note.
I have validated the Power data from my Stryd pods and can confirm the average power in Athletica is the same as the Average Power in my Stryd portal. Athletica is receiving my power data from Garmin and not Stryd; I don’t have my Stryd API connected to Athletica. @Antonie I had to turn Garmin power recording off (wrist and HRM strap) for any run session via the activity setup. As you noted reported wattage is higher than Stryd’s, this is related to the lack of Power measurement standards. For me once I turned Gamrin power off and left Stryd power reporting on via the Stryd Datascreen, I then set my Critical Power (which I took from Stryd) and once Athletica recalculated my power zones they were pretty close; with only a small amount of difference between Garmin, Stryd and Athletica in zone 2b, 3a, 3b. You may also choose to realign Garmin power zones (Threshold power) to Stryds (Critical Power).
Hopefully that helps. Let me know if you have any questions as you go through it.
I turned power on again and it seems better now. Only issue now is the difference in Z1 and Z2. Any suggestions on how to get those alligned?
@Cubicfunction thanks for your suggestions. The issue with Garmin and Stryd both recording was a while back when I was testing an alternative data field. So maybe it has dropped off the athletica measurement period now.
Sorry to pile on, I know there are a lot of other issues at the moment, but this happened again. I was wondering why my zones seemed so hard all of a sudden. My CP once again was auto-increased, from Stryd’s value of 274 to 323.
Hi @Prof
I would definitely go with Stryd API integration.
As you know Stryd recalculates your critical power and changes it automatically (optional). I think connecting to them directly would automatically adjust that data and save each user a step and avoid having to do it manually in Athletica.
Hey Christian welcome to the Athletica community … depending on your Garmin watch (assuming you don’t have a power pod / meter like Stryd) will use their own algorithms to estimate running power. You can turn it off/on your watch settings.
Sorry, I was replying to @thekappe and @jhbuchholz . I use a Stryd, switched off power on my Garmin 965 and it shows the Power data in my workouts. So for me everything ist fine. In combination with intervals.icu Athletica works really good for me. I think I will use it even after my trial.
