I came, I rocked the run-up in the first lap, I crashed (whoops; a little too much front brake!), I had a blowout.
And there, half a lap in, was my race. I was sitting about where I wanted to be (8th-12th-ish) when the whole thing went down.
Funniest thing (in retrospect): a pair of Andre Dugast tubular tires on a bike in the Men's 4B's. That's $300/pair tires in a beginner race. Ah, eagerness!
Lessons learned: I'm fast enough that I should start in the front row. Remember to bleed speed when it's muddy with the rear brake (or legs, as the case may be).
I'm sure that the postmortem on the front tube will tell me something too.
