Trouble is, I can’t figure out how to edit it. I am starting from an entirely different location but want to join the route I did half way through and follow it.
Surely this is easy?
Not really but what you can do is start from your new location, ride to where the route is (at whichever point you join it) and then fire up the old route on your head unit. It’ll start asking if you want to be directed to the start, click NO and just start following the route. It will pick it up from the point you’re on, even if it takes the unit a minute or so to work out what you’re actually doing.
Another thing that annoys me about Strava is that the desktop version is almost like different entity, and doesn’t seem to share much functionality, and looks quite different too.
Yep, a baffling lack of continuity between them.
