Imported .fit files, containing HR strap data, do not populate HR and Power zones

Since the last update, earlier this month, importing .fit files from Wahoo on the Garmin Connect website doesn't populate HR zone or data properly.

I'm using the Wahoo app on Android with my Garmin HRM strap. The files are then automatically uploaded to Dropbox and uploaded manually on the Garmin Connect website.

Even though the average was 118bpm, the entire activity was allocated on the HR zone Z1 (91-108bpm). As for the Power Zone, the entire activity was allocated on the Z5 (> 210W) even though my average was 131W.

Normally, the zones tables are included by the device (or by the 3rd party app) into the FIT file of each activity. I already saw a FIT file from a 3rd party app that used tables for the HR and Power zones that were not in the format used and expected by Garmin Connect. I do not remember though whether it was Wahoo or another app, and cannot find the thread now. I just found a similar thread, suggesting to trim the activity (for example removing just 1s) in GC and then saving: Garmin Connect vs Wahoo - Garmin Connect Web - Mobile Apps & Web - Garmin Forums. I do not know whether it will work in your case too, but it is worth of trying.

I had a chat with Wahoo about this. They reviewed my .fit file and stated it was fine and that I should be looking at it with Garmin. Is this forum the way to do this, or is there another method?

Lastly, they also stated that HR zones aren't done in their file but at Garmin? I don't know.

You can post your zipped fit file here, but we are not Garmin employees. The other method would be opening a case with Garmin Support.

Here's the last known working file I have before Wahoo released their new version of their app (Dec 5). 2023-12-04-203521-UBERDROIDAF9C-15-0.zip

Turns out ALL activities have this issues. I inadvertently went back through them and found that HR and Power zones all show the same issues.

I checked the file, and despite what they told you, the file does contain the HR Zones, but exactly as I wrote previously, in the wrong format not supported by Garmin.

HR & Power Zones in the wahoo file:

An this is the expected format in Garmin's files:

Did you try trimming the activity slightly, as previously suggested, to see whether it then gets reparsed and assigned the default zones?

No, I hadn't. However, I just did and, like the other article stated, it worked! OMG. Thanks!
