1.5-Mile Run (Cooper)

The 1.5-mile (2.4 km) run test measures aerobic endurance by timing how long it takes to complete the distance at maximal effort. Data are from Physical Fitness Assessments and Norms for Adults and Law Enforcement (Cooper Institute, Dallas TX), widely used by US police departments, the FBI, and military branches. Because the source population is law enforcement candidates, likely fitter than the general public. These norms may be faster than population-wide averages. This test is also known as the 2.4 km run test. Note: this source is an institutional monograph with no DOI and undisclosed sample sizes; it is the only publication providing full percentile tables by age and sex for this test.

How to Perform This Test

Equipment
  • Measured 1.5-mile (2.4 km) running course or track
  • Stopwatch
Steps
  1. Warm up with light activity for 5-10 minutes before beginning.
  2. Start the stopwatch when the participant begins running.
  3. Complete 1.5 miles (2.4 km) as fast as possible using any running pace.
  4. Walking is permitted but will increase the time.
  5. Stop the stopwatch when the participant crosses the finish line.
Scoring

Record the total elapsed time in minutes and seconds. Lower times indicate better aerobic fitness.

Notes

The test should be performed on a flat, measured surface. Weather conditions, altitude, and course terrain can all affect performance. The Cooper Institute protocol requires maximal effort throughout.

Frequently Asked Questions

Why are these norms faster than general population averages I've seen elsewhere?

The source population is US law enforcement candidates and officers, who are typically more physically fit than the general adult population. These norms should be treated as performance benchmarks for active adults rather than population-representative percentiles.

How reliable is the source data?

The Cooper Institute monograph is the industry standard for law enforcement fitness assessments and is widely cited in peer-reviewed research. However, it is an institutional publication (not a peer-reviewed journal article) and sample sizes are not publicly disclosed. No peer-reviewed study with equivalent age- and sex-stratified percentile tables for the 1.5-mile run was identified in the literature.

Is the 1.5-mile run the same as the 2.4 km run test?

Yes. 1.5 miles equals approximately 2.414 km. The test is widely referred to as the 2.4 km run test in Commonwealth countries and by organisations such as the British Army and New Zealand Police.

How does the 1.5-mile run relate to VO2 max?

Run time can be used to estimate VO2 max. The Cooper 12-minute run formula and similar equations use timed run performance to estimate aerobic capacity. However, the 1.5-mile run norms shown here are based on time rather than estimated VO2 max.
