Hi, I'm a runner and an MTB rider; while I use a lot the roundtrip option for running in unknown cities/places, I can't do the same for MTB riding...is there any specific reason for this? I don't think it would be so challenging to add this possibility for MTB activity. The only option we have is to use Garmin connect, navigate routes and find what suits the best for you...but that's not as much convenient as the possibility of doing it straight from your watch as it happens for running or road cycling.
