Segments & best-efforts

Segments

Cairn matches your activities against segments using PostGIS. Each matched effort is timed and ranked, producing leaderboards (KOM/QOM-style) across the users on your instance. Segment definitions imported from providers (e.g. Strava segment efforts reference their segments) are first-class entities.

Best-efforts

For supported activity types, Cairn automatically detects best efforts over standard distances/durations from your stream data, and tracks personal records. New PRs trigger notifications as part of the import follow-ups.

Browse them under Best-efforts and Records in the web UI, or read them from the API: GET /api/records, GET /api/best-efforts/history, GET /api/segments, GET /api/segments/{id} and GET /api/activities/{id}/segment-efforts.
