Balke 15-minute run test
The Balke test is a 15-minute run in which you cover as much distance as possible. Divide the distance in metres by 15 to get your average speed in metres per minute, then VO2 max = 0.172 × (speed − 133) + 33.3.
How to run it
What you need
- A 400 m track or a flat, measured route
- A timer (the VO2 Maximizer app times the test and measures the distance)
Step by step
- Warm up for 10 minutes.
- Start the 15-minute timer and run as far as you can at an even, hard pace.
- Keep moving until the time is up, then note the total distance in metres.

The formula
VO2 max = 0.172 × (distance (m) ÷ 15 − 133) + 33.3Balke (1963). Distance ÷ 15 is your average speed in metres per minute.

Records
The Balke 15-minute run has no ratified world record, the same way the Cooper 12-minute run has none. The credible ceiling comes from extrapolating world-class 5,000m runners over the full 15-minute window: roughly 5,950 to 6,000 meters for a Cheptegei-pace male athlete and roughly 5,350 meters for the women’s 5,000m world-record pace. Inside fitness-test settings, county-standard male athletes cover 4,500 to 5,000 meters and county-standard females cover 4,000 to 4,500 meters.

Balke test or Cooper test?
Both are timed distance runs. The Balke test lasts 15 minutes instead of 12; choose one and keep using it so your results stay comparable.
