Age Grading Calculator
Use this when raw time alone does not explain how strong a result is for your age and sex.
- Uses 2025 road age-grading benchmarks for common race distances.
- The 100% benchmark represents an exceptional top-level reference, not an average standard or pass mark.
- Best for comparing similar road races, not trail, heat, or workout efforts.
Age grading helps compare race performances when age and sex make raw times hard to compare directly.
- Use an official road race time.
- Choose the distance that matches the race.
- Enter race-day age as a whole number.
The percentage compares your time with a top-level 100% benchmark for that sex, age, and distance. It is not a pass mark. The age-standard adjustment describes the difference between top benchmarks, not average runners or a converted personal result.
- Compare similar road races rather than very different courses.
- Use it as context, not as a training prescription.
- Track the percentage over time if raw speed changes with age.
Calculate one recent race, then compare it with another distance only if the race conditions were similar.
