Well, nothing beats time on the track. Other things to practice: learn how to ride in a tight fast pack (do any training club rides locally)? Finessing acceleration and deceleration were important for me, as was really concentrating on being smooth predictable, and safe.
Track events are short bursts of speed, even the long ones. So, practice intervals. Run hard, take a break for 5-10 minutes and run hard again. There is lots of info out there on interval training techniques. Acceleration is very important – Being able to ride at a relaxed pace, and then go all out for 30 seconds is important. Naturally, you need to be able to spin smoothly at speeds up to 130 – 150rpm.
The strategy is only going to come through time on the track, but some of the technique can come from the road.
