Although this track stuff is pretty dang hard and, yes, a little boring, it is GREAT training and a good excuse to get out of the cold, snow and wind of the front range.
After viewing these pictures of the track, I am reminded why I NEVER look down when riding. Slippage factor... It is STEEP.
Yesterday, we did 4 "little sprints" (ie. start practice). Here is one of mine (do not take notes. It is not an example of a fast little sprint).
