I went out for my first dose of midweek pain at the San Jose Twilight crit last night. It was a blast, though I'm not sure I'd call it a crit. It is more of a really long circuit race/workout. We did 16 laps of about 2 miles each. I learned some good things, especially about how to conserve energy on the hill thanks to Irish Mike from the SJBC. I even threw down a fairly decent 'sprint' at the end, which was more of a seated drilling of the pedals (and I was off the back, so it didn't really mean anything). I still haven't figured out the best line threw the tight turn at the bottom of the hill. I seemed to find the right line about 1 out of every 3 laps.
I think I will definitely go again, because it was fun. Plus, I need to amortize my $40 SJBC club membership over a few more races (each racer has to be a club member for insurance reasons).
