It was just last year when I wrote that short-track mountain bike racing was the key to preparing for the upcoming ’cross season. Not racing the road, I still wanted to keep that edge that only real racing can give you. So, I turned to the C.U. Cycling Short Track Series. The fit seemed perfect -short, intense races that mimicked the effort and style of cyclocross racing. Because they were short, they allowed for more training on race days. I’ve added something else. Something even more intense and painful in it’s own way. Endurance racing.
