The big advantage to running is that it is much simpler. In the summer, when I run on the beach, all I need is a bathing suit. Off the beach, it isn't much more than that (add shoes, socks, and a shirt).

Yesterday I road 33 miles on fairly hilly roads. My chain fell off three times as a result of things being slightly out of whack from my recent incident. This was a bit frustrating since I had brought the bike into the shop after the incident. After the ride yesterday I headed directly back to the shop.
Saturday I was on the track and working towards my half-mile time trial.
I am looking forward to the time when a 33 mile ride in the hills doesn't leave my quads sore.
