How to Star a Segment
From any segment details page, click the star icon so that it turns orange. If you are not currently on a segment page, click "go to segment" from a ride activity page, or "View Overall Leaderboard" from a run activity page. To un-star a segment, simply click the star icon again, turning the star back to gray.
How to Find your Starred Segments
From any page on Strava.com, hover over the Dashboard tab and click on My Segments from the drop-down menu. From the mobile app, navigate to your profile and scroll down until you see the Starred Segments list.
