Add Segment start/end as markers or waypoints in Strava Routes
Garmin connect recently started implementing segment warnings in a route you create on GC.
Once exported to a Garmin device, this will show you when a segments start trough a coursepoint.
This alone works really well!
Implementing this would be a major knockout for the GC segment feature (which obviously is never going to win it from Strava anyway)
Till then, I think I'll be doing this manually ;)
