I strained a calf muscle last month, raced the next weekend anyway, tried to race the week after that and failed, rested for a couple of weeks hoping to try again, got scared away by a cold spell, etc.
Now finally, I've admitted the inevitable. This weekend I rebuilt my hubs, broke down a damaged wheel for spoke replacement and put on the road tires and fenders. Tragically, this coincides exactly (thanks to the rest and a lot of pie) with the weekend on which I became eligible for the upcoming Clydesdale Cyclocross Championship of the Universe.
Oh well, I had planned to be done by now anyway. I just didn't plan to sit out the last four weeks.
