Age-grading
noun - Age grade tables are statistical tools used in running events to score and compare race times across different ages and genders. They calculate a percentage score showing how a runner’s time compares to the theoretical world-record time for a person of that exact age and sex.

How Age Grading Works
The Standard: Maintained by organizations like World Masters Athletics, the tables list a standard baseline time for every single age (from 8 to 100+) and every racing distance.
The Math
The age-graded score is an athlete's time divided into the standard world-best time for their age and gender, or vice versa to find an equivalent "open class" prime time.
Level Playing Field
Age grading lets a 60-year-old runner fairly compete against a 25-year-old runner by neutralizing the natural slowing effects of aging.
Performance Levels Explained
100%: Equal to or better than an approximate world record for that age and gender
90%+: World-class runner
80%+: National-class runner
70%+: Regional or top local club-class runner
60%+: Local or general recreational club-class runner
Why Runners Use Them
- Track Fitness Over Time: See if an athlete's fitness is improving as they get older, even if their raw clock times are slowing down.
Race Comparison
Age grading enables athletes to judge whether their 5 km time is better than their half-marathon time.
Awards
Allow race directors to give overall prizes to masters (older) runners based on performance percentage rather than raw speed.
