Visualize an activity file

Drop a GPX, FIT or TCX file to see its route on an interactive map with an elevation profile and activity stats. Everything stays in your browser — nothing is uploaded.

How to view your activity

  1. 1

    Select your file

    Drop your .gpx, .fit or .tcx file onto the viewer, or click to browse your device.

  2. 2

    Explore the map

    The route is drawn on an interactive map with start and finish markers, an elevation profile and activity stats.

  3. 3

    Stay private

    The file is parsed locally in your browser — it is never sent to a server.

Frequently asked questions

Which file formats can I view?
GPX, FIT and TCX — the formats exported by Garmin, Strava, Wahoo, Coros and most training apps.
Are my files uploaded to a server?
No. The map is rendered locally in your browser. Your file never leaves your device.
Why is the map empty?
The file probably has no GPS data — for example an indoor trainer or treadmill session. You can still see the elevation profile and stats if they are present.
