a great ride and another broken foot

I pushed up to Croton-on-Hudson this afternoon. It was hard, a lot of climbing. Gorgeous day though, perfect temperature. The part that sucked was the realization, once I got there, that my foot was broken. How did I manage to push 30 had miles on a broken foot without realizing it was broken? Needless to say, I took the train back. I'm pissed because I won't be able to race in May.
