Age grading compares your time to the world record for your age and gender, giving a percentage score. This allows fair comparison between runners of different ages. A 60-year-old running 70% is performing equivalently to a 30-year-old running 70%.

What is a good age grade percentage?

90%+ is World Class, 80-89% is National Class, 70-79% is Regional Class, 60-69% is Local Class, and below 60% is Recreational.

Does parkrun show age grading?

Yes, parkrun displays age-graded percentages on your results page, making it easy to track improvement and compare across events.

Age Grading Formula

Age Grade % = (Age-Standard Time / Your Time) × 100
