I cruised up the street to Rage again after work, for my second go on the pump track.   I sure suck compared to the guys in the vid, but still saw some improvements over last week.   What a fun time, with a great group of laid-back and supportive people! The course takes about 10 seconds a lap, but seems longer since you are working and focusing every moment, and brushing right up against (and sometimes, into) the walls.   I resisted pump-tracking for a while, not that it wouldn’t be fun, but i figured it would not be a workout. I simply don’t have the time to be on the bike away from the family and not burn calories.   I could not have been more wrong!   Its not the same workout as pedaling, but you aggressively utilize your whole body to propel the bike via body english and momentum. After 4 or 5 laps i feel an intense anaerobic burn as my arms and hips and calves start to shake.   The crossover skills pay immediate dividends on the mtb. Can’t wait to go again, can’t wait to carve a turn and shoot out of it faster than i entered, can’t wait to to manual jumps one after another and clear a tabletop.
