Early on, you may want to do some really basic "get to know the track" drills where you put on a warmup gear and simply do things like:
- Ride 10 laps in the Sprinter's lane
- Ride 10 laps on the Stayer's line
- Ride 10 laps at the Rails/Boards
- (f the track is relatively empty) Safely and gently swerve back and forth. This trains the brain about the curves.
- No max speed efforts (to save energy for more reps)...OK maybe a couple, but remember the objective for the day.
- Ride in a paceline with others taking pulls (if they aren't elite fast).
- Don't be afraid to ask questions. I'd rather a rider ask me what he thinks is a stupid question (there are none) than have him pull an actually stupid maneuver
Also, bring your tools and feel free to tweak your bike fit.
A lower gear is important as you won't tire out as quickly and have to pack it in for the day.
Routines like this help new racers get their "track legs" faster if they can't get to the track very often. Basically, spend your limited time on the track doing things that you can only do on the track. Namely: Learning how to ride the curves. You can do strength and cardio training elsewhere.
