Accepted formats, what happens to the file, and where the data appears.

Accepted formats

If your device produces a different format, export through Garmin Connect or Strava as FIT/TCX/GPX first.

Where to upload

Drag and drop or pick from the file dialog. You can drop multiple files at once.

What happens after upload

  1. The file is parsed (per-second power, HR, pace, GPS, laps).
  2. An Activity record is created with computed metrics: * Duration, distance, elevation gain. * Normalised power (bike) or normalised pace. * IF, Load, hrTSS. * Best efforts (max 1s, 5s, 1m, 5m, 20m, 60m for power; equivalent for pace). * Power zones distribution (bike) and HR zones (all sports).
  3. Laps are stored as ActivityLap rows.
  4. If the activity matches a known assessment template (e.g. 20 min FTP test pattern), it is flagged for your coach to review.
