Strava sync.

Connect Strava in Settings → Integrations. The webhook fires within ~60 seconds of you finishing an activity. We pull distance, duration, avg HR, max HR, and elevation gain.

If a prescribed session of compatible type exists on the same date (run → run, bike → cross-train, etc.), the activity auto-links and the session flips to completed. The session detail page then shows actual-vs-prescribed.

On next week’s rebuild, the engine reads prescribed targets vs your actuals — letting it spot drift like easy runs averaging above your prescribed Zone 2 ceiling. Apple Health is the integration we lean on most; Strava is here if it’s already part of your routine.
