I've got a couple of runs I've done several times and decided to clear out old courses and make some new ones. Is there a way to apply a newly created course to previous activities that were on that course (in batch)? Or do I have to go activity by activity and do them that way (which means I won't)?
I like the Strava feature that recognizes routes that you've done previously and lets you see your progress (or regress) along those routes. You don't even have to bother with self-creation of courses it just says "hey, you do this a lot - click here and we'll group them together for you."
