What this format is
FIT is Garmin’s compact activity format. Most mapping apps want GPX. The conversion happens on this page; the FIT file never leaves your computer.
How to get the file
- From Garmin Connect
- 1. Open the activity in Garmin Connect (web).
- 2. Click the ⋯ menu on the right → Export original or Export as FIT.
- 3. Drop the .fit or .fit.gz file here.
- From Strava
- 1. Open the activity → the wrench icon → Export GPX if you only need the track.
- 2. For original FIT, request a full account export and use the Strava export tool.
What is kept and what is lost
| Kept | Lost or missing |
|---|---|
| GPS, elevation, timestamps | Device settings, lap alerts, and some manufacturer-specific FIT fields |
| Heart rate, cadence, temperature, power | Nothing in those four if the FIT recorded them — they are written into the GPX extension |
Questions
Will heart rate and power still be in the GPX?
Yes. They are written into Garmin’s TrackPointExtension (and a power extension), which Garmin Connect and Strava both read.
Is there a file size limit?
No upload means no server cap. A long ride or a .fit.gz from a bulk export is fine; the work happens on this device.
Do I need a Garmin or Switchback account?
No. Drop the .fit, run the converter, download the GPX. Nothing is stored here.
