Convert FIT to GPX turn a Garmin .fit activity into a GPX track, on your device

What the GPX file contains

• Track

  One track point per recorded position, with latitude, longitude, elevation and time (UTC).

• Heart rate, cadence, temperature

  In the TrackPointExtension used by Garmin, which most apps that read GPX understand.

• Power

  In an extension of each point, when the activity recorded power.

• What GPX cannot hold

  Laps, calories, the sport and the summary: GPX is a track format. For laps, use FIT to TCX.

Good to know

Points without a position are left out of the GPX: an indoor activity (treadmill, home trainer) has no GPX track. Use TCX or CSV, which keep every point.

Impossible positions (0°, 0°, points outside the globe, jumps across the map) can be cleared with one repair before converting, so the GPX draws a clean line.

The FIT file stays the best file to import back into Garmin Connect or Strava: it keeps everything. GPX is for maps, route planners and apps that do not read FIT.

Example

The sample “Healthy bike ride” above the drop zone is a one-hour ride recorded every second: its GPX has 3,601 track points. The first one:
