About FIT
FIT is the binary format Garmin watches and bike computers write for every activity. It is compact and carries sensor data such as heart rate, cadence and power alongside the GPS track. Wahoo, Zwift and many other devices use it too.
FIT is binary, so map tools and text editors cannot read it. FIT is the full-detail record of a workout.
