VO2max is the maximum flow of oxygen consumed by an individual during intense effort.

To summarise, 10 means that the runner can hold 90% of his MAS for 1 hour, and 5 that he can hold this 90% of MAS for 30 minutes. The greater the endurance score, the better. This duration is divided by the support time of the MAS (fixed here at 6 minutes). This long distance endurance score corresponds to the time that a runner can hold 90% of his MAS. There are different endurance scores but we use endurance defined in the MIT model, which our co-founder Guillaume Adam contributed towards. EnduranceĮndurance is the ability of a runner to run for a long time at a given intensity. MAS tests are subject to the nature of the test and the state of fitness on the day.

There are different MAS tests that can be used to estimate your MAS, although race results are usually more accurate. The races selected are those from the last 4 years and for durations between 6 minutes and 5 hours. We calculate it from past races and it’s the speed you could hold in a 6 minute race. MAS (Maximum Aerobic Speed) is the speed at which a runner reaches his maximum oxygen consumption: VO2max.
