Good in a 4/5 field. I'm really surprised nobody tried to bridge in those 20 minutes where you were setting tempo. But hey, if you can get away with it... *shrug*. Might work on a lazy Cat 3 field. Won't work at all in a 1/2/3 field. The moment the pace slows some opportunist will attack. One guy goes and maybe nobody responds if it's early in the race. Two or three go, then a lot of guys follow and the pace shoots through the roof.
I remember that course. My first year racing I was in that field. There were rain storms all day the day of the crit and that course turned slick as ice. One of my teammates slid the front wheel on warmup and landed on his face and during the race, through every corner I felt my rear wheel slide. There must have been over a dozen crashes in our race.
