These assume your endurance is as strong as your speed. Most runners grade higher at the distances they train for.

What do the levels mean?

90%+ World class · 80%+ National class · 70%+ Regional class · 60%+ Local class · below 60% Recreational. These are the standard World Masters Athletics bands. 100% equals the best performance on record for your age.

Age grading is a ratio against that standard. It is not a percentile. A score of 70% does not mean you beat 70% of runners your age; in most races a 70% runner finishes well inside the top quarter.

How is it calculated?

Each age has an age factor. Your age standard is the open (peak-age) standard divided by that factor, and your age grade is the age standard divided by your time. Your open-age equivalent is your time multiplied by the factor.

Grades are most reliable on certified road courses. Trail, cross-country and hilly courses will grade lower than your true fitness. parkrun uses its own variant, so your parkrun age grade may differ by a point or two.
