Update
Strava activities will stop syncing to RestOrTrain on September 1st
July 2026 · Antoni, co-founder of RestOrTrain
TL;DR
- What is happening: Strava changed its API policy to block AI apps from reading athlete data - even with the athlete's permission. On September 1, 2026, Strava stops sending your activities to RestOrTrain. New Strava connections are already off, and on September 1 the ride summaries RestOrTrain writes into your Strava activity descriptions stop too.
- The fix: connect your platform directly and you get what Strava never allowed - your planned workouts pushed straight to your device, and up to two years of training history.
- What to do: in Settings → Data Sync, connect the platform you record on. Garmin, Wahoo, Hammerhead, Zwift, and Rouvy connect directly; everything else reaches RestOrTrain through Apple Health or Intervals.icu. Keep Strava connected until the replacement is syncing.
- Platform missing? We're sorry this happens - please tell us through the feedback form in app Settings, and we'll do our best to cover it.
Why is this happening?
Strava updated its developer policy with a new rule: AI applications can no longer read your training data. The exact words are "ingestion into a context window" - in plain language, an AI that looks at your ride to answer your question about it. That is what RestOrTrain does, so the rule applies to us - even though you gave us permission to read your own data.
The policy is public - you can read the full text yourself. It applies to every AI app, with one exception: AI that runs through Strava's own connector, available to Strava subscribers.
We believe your training data belongs to you. But this is Strava's platform and Strava's rule, and it seems there is nothing we can do about it.
What exactly changes
Until September 1, 2026: if Strava is already connected, it keeps syncing as normal. After September 1: no new activities arrive from Strava, and RestOrTrain stops writing ride summaries into your Strava activity descriptions.
The upgrade: workouts sent to your device
Here is the genuinely good part. Strava's API only let us read finished rides - it had no way to deliver a planned workout to your device. Direct connections do.
Connect Garmin, Wahoo, Hammerhead, Zwift, Rouvy, or Intervals.icu, and the workouts on your RestOrTrain plan are sent ahead of you: as a structured workout on your watch or bike computer, ready to ride in Zwift or Rouvy on the day they're scheduled, or onto your Intervals.icu calendar.
