As it stands, creating a simple course is a pain. I've resorted to using third party apps to create GPX files which I then import via the stages website. However, this option is not available in mobile mode and even if it were, it makes creating a route while on the go pretty much impossible.
I wish there was some way to just either create a route directly in the mobile app which would quickly get synchronised with the device (as I currently do on my Suunto) or import a GPX file in the app (which, again is available on my Suunto).
Of course, I could be wrong and I just haven't figured out it's already possible, so I'm very open to feedback.
