Cooper formula for a 12-minute run.
How it works
Estimate VO₂max from a Cooper 12-minute run test result.
Who it's for: Runners and fitness enthusiasts gauging aerobic capacity without lab testing.
VO₂max reflects maximum oxygen uptake — higher values indicate better aerobic fitness.
Uses the Cooper formula with distance converted from miles to meters.
Distance should be from a maximal 12-minute run on a flat course.
How to use
- Run as far as you can in exactly 12 minutes and record the distance in miles.
- Enter Distance in miles (e.g., 1.5 for a typical fit adult result).
- Optionally enter Age for context — the Cooper formula does not use it in the calculation.
- Read VO2max in ml/kg/min.
Good to know
- Warm up thoroughly; consult a physician before maximal effort if you have cardiovascular concerns.
