Question 1

Which file formats does Re-Track support?

Accepted Answer

Re-Track supports .FIT (used by Garmin, Wahoo, Polar, Suunto, and most modern GPS devices), .TCX (an older Garmin format), and .GPX (a universal GPS format supported by nearly every platform).

Question 2

Does it work with Wahoo, Coros, or Suunto files?

Accepted Answer

Yes. Any device that exports a standard .FIT or .GPX file works with Re-Track. This includes Wahoo Elemnt, Coros Vertix/Apex, Garmin Edge, Suunto, Polar, and others.

Question 3

Does Re-Track store my activity files?

Accepted Answer

Parsing and file generation happen entirely in your browser. When you download a corrected file, an anonymised record of the repair session is stored to improve the service — speed, HR, power, cadence, and altitude readings, but never GPS coordinates or route data. No account, name, or email is ever linked to this record.

Question 4

Do I need to create an account?

Accepted Answer

No. Re-Track is completely account-free. You upload, edit, and download — nothing else required.

Question 5

Is Re-Track free?

Accepted Answer

Yes, entirely free. There is no paywall, no premium tier, and no ads.

Question 6

Why is my distance showing as 0 km?

Accepted Answer

This happens when your device recorded an activity without GPS — typically an indoor ride on a trainer, a treadmill run, or any workout where GPS did not lock. Upload the file, type the correct distance, and download. The file is fixed.

Question 7

Garmin Connect or Strava rejected my corrected file — why?

Accepted Answer

Both platforms validate basic sanity checks on import. Make sure your edited distance and duration are realistic for the activity type. For .GPX files, the corrected stats are injected as metadata — some platforms may still display the GPS-calculated distance instead.

Question 8

Can I upload a file exported from Strava or Garmin Connect?

Accepted Answer

Yes. Both platforms let you export your activity as a .FIT or .GPX file. Upload that file to Re-Track, make your edits, download the corrected version, and re-upload it.
