If you can d'ld a route from routeslips, don't know about it. I did find a route there, print it out, add on to it. Then went to www.bikeroutetoaster.com laid out the route and d'ld to my puter. Then I imported it into training center and used that to load it onto my G.

I understand that in TC you can input things like "turn left onto" or "convenience store" or "coffee shop". These will then pop up a certain distance ahead.

BTW, when you create the course, it will give you an estimate of distance, elevation, etc. The estimate was about a mile short, or less.
