Ride With GPS won't allow cropping except with subscription. I have a lot of 4-mile rides now that should be 3.7 since I didn't turn off the app for ten or twenty minutes. It's also throwing some weird elevation bugs. But when the ride is loaded over to Strava it does some error checking, I guess, and there I can crop it. I should try Strava's watch app and see if it picks up heart rate. Might go back if it does. But Strava is still showing me a much higher power estimate from going faster on my road bike than the MTB, even though the heart rate is about the same.
