One thing I did love about the physical therapist-- she never acted like there was anything strange about training for a 50K or 50M race. (Good rec, Jen!) Plus, she said there was nothing wrong with running as long as my knee wasn't hurting. Lovely... more trails soon!
Just to let everyone know: Sports Basement is a dangerous, dangerous place. I think one should never venture in there without specific limits on both time and money to be spent.
