Sounds like we've got similar stories! Cycling was my cross-training for running, but I'm quickly becoming addicted and it looks like it's going to wind up being the other way around for me, too. Cycling beats my bones up less, and allows me to be outside working out for longer periods of time-- definite bonuses!
