Actually, if you don't have an altimeter, Bikely does a reasonably good job of estimating the amount of climbing on a route.

Here's the elevation profile for a ride in Marin that I had mapped out on Bikely (the route itself is here ):


And here's the elevation profile from my bike computer when I rode that route:


Bikely estimated about 3200 ft of climbing and my computer registered about 3500 ft. - which is pretty good agreement, methinks.
