Beep Test Calculator

Beep Test Calculator

The beep test, or multi-stage fitness test, is a standard 20-metre shuttle run used in schools, the military and team sports to measure aerobic capacity. Enter the level you reached and this calculator estimates your VO₂ max and rates your fitness against general adult benchmarks. Use it to test endurance, track progress, and set your next level target.

The beep test (20 m multi-stage shuttle run) ramps up running speed every minute until you can no longer keep pace. From the level you reached, this tool estimates running speed (8 + 0.5 × (level − 1) km/h) and predicts VO₂ max with Léger's adult formula (5.857 × speed − 19.458). As a rough adult guide, a VO₂ max under 25 is poor, around 35–43 is average, and over 52 is excellent — norms shift a lot with age and sex, so track your own trend.
