Red, Yellow, Green

Green means go. Intervals, the true path to Valhalla. Nothing is more universally accepted as the hallmark of glory in training culture as the interval session. To become one of the initiated you must destroy yourself eight times with a sixty second recovery. Yellow means go faster. We discuss the impact and the structure of intervals in our culture and suggest the best definition of intervals. How should intervals actually be used, and how do we make decisions about what constitutes good training? Red means floor it.
