FIT is the activity file saved by many watches and bike computers. Drop the .fit file. This page reads the GPS positions and draws the path, with time, elevation, and speed when the file recorded them.

How to view a FIT file

  1. 1

    Export the activity

    Save the activity as a .fit file from the watch or its app.

  2. 2

    Read it here

    Drop the file. The browser reads the positions. Nothing is sent to a server.

  3. 3

    Save or edit

    Export GPX, KML, KMZ, or CSV. FIT is not written back. To change the path, open the GPX editor.

What the map shows

  • The GPS path, with time, elevation, and speed when the file recorded them.
  • Each sport, when the file marks them separately, is its own part.
  • Heart rate, cadence, and power stay in the FIT file. They are not drawn here.
  • An indoor activity with no GPS positions cannot be drawn. The page will say so.

Privacy

Your file never leaves your device. There is no upload and no account. Closing the tab drops the track from this page.

Questions

Does the FIT file get uploaded?

No. The browser reads the file where it already is. GPS Toolset does not receive a copy.

What is a FIT file?

FIT is the activity file saved by many watches and bike computers. This page reads the GPS positions and draws the path.

Where are heart rate, cadence, and power?

Those stay in the FIT file. This page shows the path, time, elevation, and speed when the file recorded them.

The activity has no GPS. What happens?

Some indoor activities have no positions. This page cannot draw those, and it will say so.

Can I download a GPX?

Yes. Export saves GPX, KML, KMZ, or CSV. FIT itself is not written back. To change the track, open the GPX editor.

The file has more than one sport. What is shown?

When the FIT file marks each sport separately, each one is its own part. Pick a part to see it on the map. A GPX download keeps every part.
