Mapmyride.com
I just discovered this website that is perfect for mapping rides and race courses. It's a lot like Google maps, but it can give you the elevation profile (YAY!) for a route - perfect for getting to know an unfamiliar race course or new route. I love knowing elevation profiles. It also allows you to create the route just by clicking on points on the map.
For those racing this weekend, here is the map I made for Jeff Cup. If the elevation profile doesn't show up initially, there should be an option for it in the left tool bar.
