Manual archive import is the beta setup path for new athletes. Use the beta access code and your original Strava archive ZIP or FIT/FIT.GZ fallback. Email can be added now for login, or skipped for a test import if you save the recovery code.

Manual archive import

Archive import for deeper history

  1. Use the beta access code from your coach.
  2. Upload the original Strava export ZIP.
  3. Keep this tab open until the completion page appears. Keystone may keep processing after that.
  4. Save the recovery code shown on the completion page. It is shown once.

Use this path for the most complete first-time ZIP onboarding, archive completeness, older history, or when you prefer not to connect Strava.

Use the original Strava export ZIP for first setup. FIT/FIT.GZ files are accepted only when the ZIP is unavailable or for later gap fills; TCX and GPX entries are skipped today.

Where is your trainer usually located?

Keystone applies this only to indoor rides; outdoor rides keep their recorded elevation.

Help Keystone start smarter

Optional cycling anchors. Keystone will replace formula priors with field estimates after import.
