Track - yes!!
Love riding track. I think the most important thing to learn is track etiquite - how to enter and exit and the track terminology - stick, stay etc. Because you have no brakes this is essential for safety. We also did drills on the track when training - it is like playing games on a bike - island hopping, pyramids, miss n out etc. Lots of great advice in earlier posts - we need more tracks and riders in the US! Riding track also teaches you to be comfortable riding close to others and how to relax on a bike. Have fun!
