Strava (http://www.strava.com/) is similar to MapMyRide, I just happen to be a major fanboi of it. The King of the Mountain achievements are really cool to me. I might have to do a ride down the Mt Vernon down to your hood this weekend and check it out.
Does Strava have an AQndroid App? I like that the MapMyRide website has the Apps and connects to your phone's GPS. Gives you the time, distance, elevation, etc.
