I went to the track for the first time last night. It was pretty exciting and I think I'll be moving from road racing to track
The coach went around the track with me a few times to explain the lanes, how to pass someone and how to ride in a paceline. Then he sent me to warm up and paceline with a couple people on the blue line. I got to be in a mock individual pursuit, points race, and elimination race. Take a class if you can, I really would have felt clueless without that instruction.
It was a little weird getting used to the slope of the track and if you've never done any roadie stuff then get used to riding really close to other people.
