Strava Ranks by Jelle Buitenhuis

Strava Ranks shows your rank on every Strava segment, straight in the segments table of an activity.

Strava stopped showing much of this in its interface, but the data is still there. Strava Ranks puts it back:
1. Your personal rank, total attempts and the percentile of your best effort, on every segment
2. Sort the segments table by any column: distance, elevation, time or your rank
3. The complete list of your attempts at a segment, including the slow ones
4. Working analyse buttons: jump from an activity or a running/bike segment straight to the analysis page
5. The extension only runs on strava.com, has no server of its own and sends your data nowhere.
