Fixing a recovered FIT from an accidental discard

I accidentally hit "discard" on a recent ride and am trying to recover the data.

I did manage to extract the deleted FIT file from my Garmin 530 but as others have reported (used TestDisk), Garmin Connect won't accept it.

Online FIT tools don't seem to be able to handle fixing it, aside from the very first part of the GPS track.  Ride was ~105KM and recovered FIT file is ~165KB.

Can anyone offer any pointers? TIA!

  • ...update - tried a demo version of the Fit File Repair Tool https://www.fitfilerepairtool.info/ and it recovered the first ~20 minutes but also said "107567 bytes of the file are corrupted and could not be repaired". I don't think this is a good sign :-(

  • Fit File Repair Tool Has the ability to fix most corrupt files. It does require the paid version in order to export a repaired file.

    If you want to zip then attach your file here, we could give it a try.

  •  thank you for the offer!

    Here's a zip of the FIT file. This was extracted using TestDisk, although I tried with Recuva as well and got the same result (plus a livetrack.dat file that I think might also have some data but can't figure out how to get at yet).

    *edited to remove file*

  • After recovering a deleted file, you will almost always have some bizarre timestamps and GPS data in the fit file, such as this. These need to be manually deleted.

    After doing that you still only have the starting portion of the ride, as you mentioned.

    If you've enabled LiveTrack and you sent the link to your LiveTrack to yourself or someone else, with "Extend Session," and it's not past 24 hours ago, you might be able to recover the GPS track using a LiveTrack converter, such as LiveTrack export (dsantini.it). Keep in mind that doing it this way, you'll be missing a lot of the metrics you would typically have. You'll have the track on a map, elevation, pace, and heart rate, but not much more.

  • Thanks for trying. I did try the LiveTrack export but as I had discarded the activity, the LiveTrack session was closed at that point (I think) and I couldn't get anything from the previous URL that was shared in the email.

    Looks like the ride is toast!
