6-Minute MAS Test

PRIMED's build of the half-Cooper protocol — cover as much ground as possible in 6 minutes to find your Maximal Aerobic Speed, then take it straight into the MAS Trainer.

If you're on a standard track, tap Lap Complete each loop and we'll total it for you.
How the test works
Run continuously for 6 minutes, covering as much distance as possible — pace yourself, this isn't a sprint from the gun, but it is a maximal sustained effort.

Your Maximal Aerobic Speed is simply your total distance divided by 100 (since 6 minutes is exactly 1/10th of an hour) — e.g. 1500m covered = 15 km/h MAS.

On a track, tap Lap Complete each time you pass the start line and we'll total your distance automatically — you'll just need to add any partial final lap at the end. Otherwise, enter your total distance manually once the timer ends.
