VO2 Max Calculator

VO2 max is a strong predictor of endurance performance, but gold-standard measurement needs a gas-exchange lab. This page uses a running time-trial and body weight, or a simpler age-based model, to output a number you can track month to month. Illness, altitude, and a bad test day can swing the estimate—trend lines beat single scores.
