Balke 15-minute run

This 15-minute run test, designed by Bruno Balke, is one of many field tests designed to measure aerobic fitness. This test has a formula to predict VO2max from the run distance.

The original formula by Balke:
VO2 = 6.5 + 12.5 x kilometers covered.

Another formula (Horwill, 1994):
VO2 = 0.172 x (meters / 15 - 133) + 33.3
