I'm definitely all about RWGPS!
and I really understand your situation (you can see my similar previous post here). I've found a number of aps online, tried half a dozen internet mapping sites and taken a bit of advice from HFC Mike who tends to be the guru at this kind of stuff.struggling to take a ridden activity and mess with it to create a new route
I've seen you mention this "in yellow" thing before.I solve this (as I've expained to Tim) by never using my Edge 810 to follow a course. Instead I just set the course to display on the map at all times in bright yellow and visually follow it (or not) on the map, i.e., I don't ask or want the GPS to tell me where and when to turn.
From the Edge 810 manualPray tell, how does one change that line's colour?
