Why is that ^ not embedding?
You have linked to the trip, rather than the route. If you Map a route and log it as a ride at the same time then all of the links to that route redirect to that trip. Which I imagine is good for some people, but I find quite annoying.
If you hover over the link to the route in RWGPS you can see what the URL should be and update your post manually (something like www.ridewithgps.com/routes/12345).
I always log rides separately to routes to avoid this "feature".
