Here's another confession: Starting to regret putting the standard double on my bike last summer and then getting so incredibly f***in out of shape over the winter that I had to stop and walk up two hills today, as well as stop just about every mile to get my heart rate down from 180+. I wasn't even trying to push myself, had I gone any slower I would have never made it home from my 13 mile ride :-( It's amazing how just a few months can destroy your fitness level.
