VO2max is defined as the maximum amount of oxygen the body can utilize during a specified period of intense exercise, usually 30 seconds to 1 minute. It is said to be the gold standard of cardiorespiratory fitness, and therefore unsurprisingly, having high value as a strong correlation with long-distance triathlon performance. Think of it like the size of your car engine; of course, we want a big one!



The aim of this session is to develop VO2max, this means the intensity is high! The session consists of 4 x 1km reps, all above threshold running speed. We descend the reps, with each one getting progressively faster.
