Age Grade calculation determines a relative race result for males and females and to compare races of different distances. For example, the result can be used to compare times between two runners with ages 35 and 65 years. Calculations are based on empirical data. For each age/sex, 100% is the fastest recorded time for the distance. Please note that irregularities and conditions of your running course may affect results. A runner who scores in the 90% range is considered a worldclass runner, 80% range is considered a nationalclass runner and and 70% range is considered a localclass runner.
This system was developed for the World Masters Athletics, an organization promoting and supporting Master Athletes (age 35 years+) through international racing events.
