FAQ

What VO2max is 2,400 m in 12 minutes?

42.4 ml/kg/min. 2,400 m is 1.49 miles: 35.97 × 1.49 − 11.29. Your maximal aerobic speed is about 7.7 mph (12.4 km/h).

What 10K time does a 2,800 m Cooper test predict?

About 46:48, with 22:17 for a 5K and 1:44:26 for a half marathon. That is a maximal aerobic speed of 14.5 km/h, held at a lower share over longer races.

How is VO2max calculated from the Cooper test?

With Kenneth Cooper's 1968 regression: VO2max = 35.97 × miles run in 12 minutes − 11.29, in ml/kg/min. It was built by comparing the 12-minute run with treadmill tests.
