How Does It Work?

Your cardiorespiratory fitness level (VO2max) offers good insight into your ability to maintain a certain level of performance over a period of time. VO2max provides a strong basis for predicting how you will perform in in an endurance event, but your VO2max isn’t the only thing that matters. The work you do to prepare should be considered too.
