This 15-minute running test requires participants to cover the maximum distance possible in 15 minutes. This test, designed by Bruno Balke, is one of many running field tests designed to measure aerobic fitness. This test has a formula to predict VO2max from the run distance.
Participants run for 15 minutes, and the distance covered is recorded. Walking is allowed, though the participants must be encouraged to push themselves as hard as they can.
To ensure that participants don't just run down a big hill to get a good time/distance, you are required to run a looped circuit or perform shuttles between two markers. The loop/shuttles can be can be anywhere from 0.5 to 1.0km in distance.
VO2 max refers to the maximum amount of oxygen you can utilise during exercise. It's commonly used to test the aerobic endurance or cardiovascular fitness of athletes. It's not the same thing as heart rate, though it can be just as effective, if not more so, to measure and track your fitness progress.
You can use Balke's formula below to work out your predicted VO2 Max using the distance achieved during the test. For those without a calculator, do not panic, your score will be displayed on the Mettle leaderboard.
Balke's VO@ Max formula:
VO2 = 6.5 + 12.5 x kilometres covered
You can compare your score against the table below to see where you rank in terms of fitness and age category.
