How to fix corrupted .fit file?

Hi guys,

I went to a long run last Saturday and, after saving the activity, I realized that it did not sync with GCM.
I tried to do it manually, but a message "One of your files was not accepted by the system..." shows up.

I downloaded the fit file repair tool, which solved part of the problem, however all info is messed up.
Watch shows only about 14 minutes of HR in a 1h45min run.

I was using the strap and the data from the strap looks fine as I can see in the phone, however the one from the activity is messed up. I also downloaded it from the strap, but file is still corrupted.

If I look in the activity "Laps", it seem the HR was OK for all laps.

When I used the fit file repair tool, I managed to import the file to Komoot, but the GPS data looks all messed from certain point.

Does anybody know how to fix it (if it is actually fixable)?

Thanks in advance.

I see you used the HRM-Pro which can sometimes cause issues with corrupt files. Calling on Former Member to see if that is the case…

Attach your fit file here so we can take a look.

Zip the file, then in a reply post Insert >> Image/video/file >> click Upload >> browse for file >> OK.
Or upload the fit file to a file sharing service, such as OneDrive, Google Drive, Dropbox, etc., make the file public, then paste a link to the file in your post.

Update the HRM firmware How Do I Update the HRM-Pro Software Using the Garmin Connect App?
Note that HR data download after the activity is usually for swimming or when for some reason you could not wear your watch during an activity.
During the HRM-Pro download process keep the strap and watch in close proximity
If issues persist even after the firmware update, contact Garmin Support
More here about corrupted HR data: Corrupt FIT File Repair Requests

Some suggestions to help minimize the occurrence of corrupt fit files:

Sync your device then remove all activity fit files from your Garmin device using these directions - Removing Recorded Activities on a Garmin Fitness Device
Regularly check for firmware updates using Garmin Express
Let us know when you encounter corrupted files again

Hi seilogramp, Former Member.

Thank you both of you for the support.
File is uploaded and working fine, HR and GPS are now OK.
Only the calories are still weird, but I don't think it is used in any performance metrics, so I am happy with the results.

I indeed downloaded the HR. That will be the last time, I didn't know it could this kind of issues.

Enjoy your day!
;-)

Hi @seilogramp wondering if you could support me to fix mine... I tried everything and this is boring me too much since I'm a data addicted.

There doesn't seem to be anything wrong with this fit file. It uploaded perfectly fine to my own Garmin account.

Hi seilogramp,

Many thanks first of all. Actually it is the calories totally low and not in line in the exercise. Second time I use an external chest strap heart monitoring and happened it… I would like to exclude this additional info (believing that the watch kept anyway the wrist one).

is that possible according to you?

thanks again!

So, this is not an issue with a corrupt file, rather the way your fenix 5 Plus is calculating calories burned. Is this happening on every run? You can also edit the calories burned from the activity in Garmin Connect Web. FWIW, I'm not the "calorie expert," rather give that title to trux & e7andy.
