what exactly is track cycling? i got into mountain biking and road biking over past year and love it! mountain biking is a rush, especially when barrelling downhill at 40mph dodging trees and what not! very intense and very hard on the body with all the climbing hills and holding on! road cycling can get boring but it is a great way to get your endurance/cardiovascular health up. sprinting on a road bike is fun and it is fun to see how fast you can go before your legs just tighten up. good to see ya back around base and love that avi!
