Age grading compares your time with the best possible for your age and sex, so a 70 year old and a 25 year old can see who ran the better race. Most club runners score between 50 and 70%.

The working

A man of 50, 5K in 22:00

The 2020 open standard for men's 5K is 12:51. The age factor at 50 is 0.8796, so the age standard is 12:51 ÷ 0.8796 = 14:37. Then 14:37 ÷ 22:00 = 66.4%.
