This calculator uses the Rockport 1-mile walk test equation with weight, age, sex, walk time and finishing heart rate. It estimates oxygen capacity in ml/kg/min and runs fully in your browser.
A good score depends on age and sex. Higher values usually reflect better aerobic fitness. This tool compares your result to age-and-sex adjusted ranges and highlights low, fair, good and excellent categories.
Consistent aerobic training helps most: brisk walking, cycling, jogging, intervals and hill work. Start gradually, recover well, and retest every 4–8 weeks under similar conditions.
