I'd like to upload a course into GC, simple as that. I know that I can first upload a GPX/TCX file manually as an activity and then create a course from that activity. The thing is, while doing so, this activity also gets posted to other connected services (like Strava for instance). Normally, I'd like to share all my activities on Strava (because not all my contacts have Garmins), but an uploaded course is not an activity (as I haven't actually ran it yet :-)).
I also know that I can put the GPX/TCX file directly on my device, but I also want it in GC to be able to review/prepare for what's coming.
Is there some other way to do this?
