Cooper Test Calculator
Estimate VO2 max from your 12-minute Cooper test distance.
How runners use this tool
The Cooper 12-minute test is a classic field test for aerobic fitness. Enter the distance you covered to estimate VO2 max.
- Run as far as you can in 12 minutes on a flat course or track.
- Enter the total distance covered in meters.
- Review the estimated VO2 max and fitness band, then retest every few weeks to track progress.
How to use the result
- Use the full VO2 max calculator to compare Cooper results with race-based estimates.
- Translate fitness gains into training paces with the training pace calculator.
Formula and assumptions
- Cooper test estimates are field approximations, not lab measurements.
- Pacing strategy and course surface affect the distance you can cover in 12 minutes.
Worked examples
- Beginner: 2,400 m in 12 minutes → Estimated VO2 max band. Creates a baseline aerobic fitness marker.
- Race prep: Retest mid training block → Fitness trend vs prior test. Tracks aerobic progress between races.
- Advanced: 2,900 m Cooper result → Higher aerobic capacity estimate. Useful for comparing training cycles over time.
