What is age grading?
Age grading lets you compare running times independent of age and sex. The method assigns a "standard" (world-class) time to every age and sex at a given distance; comparing your time to that gives you a performance percentage.
100% corresponds to a world-class performance for your age and sex. This makes a 60-year-old's and a 30-year-old's results comparable — or your own versus last year. The calculation is based on the official road factor tables of World Masters Athletics (WMA).

Frequently asked questions
What does the performance percentage mean?
It shows how close you are to world class for your age and sex. 100% is world-record level; above 80% is national class, above 90% world class.
What is the age-graded time?
It is the time your current result would be worth in the open category. This lets you compare a younger runner's time directly with your own.
Which tables is it based on?
On the World Masters Athletics (WMA) 2020 road age-grading factors and open standards, from 5K to the marathon. These are the official reference tables of international masters athletics.
