Retrace
Step one

Load your files

Drop a GPX or TCX file. If it already contains heart rate — most Strava and Garmin exports do — that is all you need. If your track came from a device that does not record heart rate, such as an inReach, add a second file from your watch and Retrace will join them on the clock.

Read this before you trust the map. It says where the record is solid and where it is guessing.
