Age-Graded Performance vs Your Race Time
Formule
## Age-Graded Running Performance Age grading adjusts race times to account for the natural decline in performance with age, allowing fair comparison across all ages. ### Simplified Model **Age Factor = 1 + 0.0005 x |Age - 28|^1.8** **Age-Adjusted Time = Actual Time / Age Factor** **Age Grade % = World Record / Age-Adjusted Time x 100** This simplified model peaks at age 28 and applies a power-law decline. Official age-grading tables from World Athletics use detailed lookup tables derived from age-group world records.
Exemple Résolu
A 45-year-old runs a 5K in 25 minutes (world record approximately 12.7 min).
- 01Age factor = 1 + 0.0005 x |45-28|^1.8 = 1 + 0.0005 x 17^1.8 = 1 + 0.0005 x 186.1 = 1.093
- 02Age-adjusted time = 25 / 1.093 = 22.87 min
- 03Age grade = 12.7 / 22.87 x 100 = 55.5%
Questions Fréquentes
What age-graded percentage is good?
Above 60% is local competitive, 70%+ is regional class, 80%+ is national class, and 90%+ is world class. Anything above 100% indicates a result better than the known world record.
Why is this simplified?
Official age grading uses detailed tables based on age-group world records for each distance and sex. This calculator uses a mathematical approximation that captures the general pattern.
At what age does performance peak?
Distance running performance typically peaks between ages 25-35, with the exact peak depending on the distance. Marathon runners tend to peak slightly later than sprinters.
