What is the Age Graded Running Calculator & How does it work?
Age grading is a method used in athletics to adjust performances for differences in age. It allows runners of different ages to compete on an equal footing by comparing their times to the world record time for their specific age group.
\text{Age Graded Time} = \frac{\text{World Record Time}}{\text{Performance Factor}} \times \left(\frac{100}{\text{Athlete’s Age}}\right)^b
var = meaning
The performance factor is a constant that depends on the event distance. For example, in a 5K race, the performance factor might be 0.98.
