As for warm up depends on the type of race and the category. Cat 5 crits usually accelerate to maximum efforts from the gun, so you need to have done a fe short maximal efforts in warm up. Road races, particularly in higher categories often start out slower and you can warm up a bit in the race. I'd plan a little more than a half hour. Try 15 minutes spin, 5 minutues tempo. and then a couple of 2 minutes at 8/10ths, and 2 or 3 all out efforts for 30 seconds. Then 5 minutes cool down spin and then go race.
