Get a good warm-up in, get to the line with a sweat going.
Start as near the front as you can get.
Clip in fast, but relax and don't fumble it.
Expect a "leg check" for the first few laps which weeds out non-hackers and people who didn't warm up.
Don't stare at the dude directly in front of you.
Watch out for guys who can't corner for ****.
