I'm sure you ladies already know about the miracle that is Map My Ride, but if you don't, you should definitely check it out: http://www.mapmyride.com/ Not only can you click along roads to show your exact route, but it automatically fits your route to those roads. And, best of all, it tells the exact elevation and shows your elevation profile, as well as telling you exact distance!

Let me just say that this is the most fun I've had on a web site in a long, long time, and it enabled me to find a backroads route all the way from my work to my home: http://www.mapmyride.com/ride/united...ster/601475168
