I don't like warming up, I get bored.
Consequently, it takes me longer into the race to get warmed up.. and I saw more wins in Cat 3 when I was there than I saw in Cat 4 or Cat 5. In the Pro/1/2 races my best finish is 3rd, which is actually my most memorable accomplishment (I was ~12th when the field broke to sprint) because I felt so fresh and ready by the end.. and after missing all of last year I got torched in my one race this year. But alas.
I wish there were Mt. Mitchell/Bridge-to-Bridge type rides around here that were actually organized as a race.
