In light of Runtastic’s decision to retire web features, our previously published method for moving your activity history from Runtastic to Strava is no longer functional. Unfortunately, the files provided via Runtastic’s current export feature are not formatted properly for direct upload to Strava.
We are sorry to learn of the inconvenience this has caused some current and prospective Strava athletes.
At this time, there does not exist an official method for uploading activity files exported from Runtastic to Strava. We cannot endorse nor provide support for third-party workarounds, which may prove unreliable as they may not employ approved uploading methods. Runtastic and other third-party developers are welcome to use our API to build a syncing integration.
