Estimate VO₂Max

VO₂Max is shorthand for the Maximum Volume of O₂ your body can use.

You inhale oxygen. Your heart pumps it to your muscles. They combine it with glycogen and fat to produce the energy they need to propel you. The volume of oxygen you can consume is related to how hard and fast you can go. Accurate measurement requires a sports lab, but you can estimate it from a training run - even if that run is not flat out.

• Training Calculators

  • Estimate VO₂Max
    Estimate your VO₂Max based on pace, heart rate, age, weight and gender
  • Heart Rate Zones
    Uses your resting and max heart rates to calculate percentage zones for HRM training.
  • Training Pace
    Enter a race time, and find out how fast to run in training.
  • Your BMI
    Want to calculate your BMI? Our BMI calculator does what it says.

• Race Time Predictors

  • Race Times
    Just done a race? Want to know what your equivalent time would be for a different distance?
  • Marathon prediction
    Most standard predictors (including the one above) predict marathon times that many of us struggle to achieve. This article offers a more accurate prediction, and advice on how to beat it.
  • Tanda Marathon Calculator
    Calculate your marathon time based on your training volume and pace.
  • Riegel Calculator
    Fine tune the predictions in your training log by recalculating your Riegel number.
