Age Grading

Can you explain age grading and age graded times? Age grading is a way to compare the performance of runners of all ages and both genders with one another on a level playing field. When your time is “age-graded” it is calculated as a percentage of the “ideal” time for your age and gender at that distance. This allows races to give awards to the runners with the best performance for their age. It is also frequently used in team scoring so that awards can be given to the teams whose runners turned in the best performances.
