The Cooper test asks you to run as far as possible in 12 minutes. A “good” Cooper test score depends entirely on age, sex, and training status — but the rough benchmarks: 2,400-2,800m (1.49-1.74 mi) is average for an untrained adult man, 2,000-2,400m for an untrained adult woman, and 3,000m+ is the threshold for “excellent” cardiovascular fitness in any healthy adult.
The Cooper test was developed by Dr. Kenneth H. Cooper in 1968 for the US Air Force as a fast field test of aerobic fitness. It correlates well with VO2 max (within ±10%) and remains the most-cited cardiovascular field test in research literature 55 years later.
The Cooper Test Protocol
- Warm up with 10-15 minutes of light jogging + dynamic stretching
- Run as far as possible in exactly 12 minutes on a flat, measured course (a 400m track is ideal)
- Maintain a steady, near-maximal pace — too hard early and you collapse, too easy and you under-test
- Record total distance in meters or miles
The test estimates VO2 max via Cooper formula: VO2 max ≈ (distance in m − 504.9) ÷ 44.73. So 2,800m = ~51 ml/kg/min VO2 max.

What Cooper Test Distance Actually Predicts
- 2,800m+ for men: ~51+ ml/kg/min VO2 max — top 30% of population
- 3,200m+ for men: ~60+ ml/kg/min — competitive amateur athlete
- 3,600m+ for men: ~70+ ml/kg/min — sub-elite
- 2,300m+ for women: ~40+ ml/kg/min — top 25%
- 2,800m+ for women: ~51+ ml/kg/min — competitive
FAQs
What is a good Cooper test score for the army?
The US Army does not formally use the Cooper test, but the closest equivalent (a 2-mile run) needs to be completed in under 19:30 for men 17-26 (passing) — that’s roughly 3,260m in 12 minutes. UK and other militaries set similar standards.
Is the Cooper test accurate?
Cooper test results correlate with lab-measured VO2 max within ±10% for trained runners. For untrained or elderly populations, the correlation weakens — pacing inexperience adds noise. Still the most accurate field test of aerobic fitness short of a treadmill VO2 max test.
