Age Grading Calculator
Age grading converts your race time into a percentage of the approximate best possible performance for your age and sex, so a 55-year-old’s 10K can be compared fairly with a 25-year-old’s. The tool reports the age-graded percentage, the achievement class (world/national/regional/local) and the open-class equivalent time.

Notes
- Factors are a smooth approximation of WMA-style age standards, accurate to roughly ±2%; official age-group records use the exact published tables.
- Age grading assumes road races on legal courses in reasonable conditions.
- Educational estimate for sport and training purposes, not professional coaching or medical advice.
