I've stopped using Strava for the same reasons.My back was niggling so rather than sit, I have been another walk which helped. Ended up getting carried away and did nearly 6 miles up the hill trail.
Met a guy on a fancy Specialized e-bike zooming up the hill. Out of curiosity I have checked the Strava segment and lo and behold, he has not disclosed it as being an e-bike. These people are starting to spoil Strava for those of us who like to compare how we are doing with others in the same age bracket.
Maybe I've lost the competitive mojo.
