Hi Marco, to serve our athletes better and to ensure we’re around for the long run, a few of our free features that are especially complex and expensive to maintain, like segment efforts, are now part of a Strava subscription. The
impact of these changes on the API include:
1. Segment Leaderboards are no longer available via the API
2. Segment Efforts will only be available for Strava subscribers
We realize these changes could be especially challenging for some of you, so they’ll be non-breaking for 30 days, returning empty data during that time so you can make necessary adjustments. After June 18th, those endpoints will either omit the data or return an error message. You can find more details
here.
