This calculator is intended to provide you with an age-graded race time and an achievement percentile for a recent performance at a specific race distance. Age-graded information allows you to:
Adjust your performance to what it theoretically would have been during your prime running years (your 20's and a portion of your 30's depending on the race distance).
- Judge your performance, using an achievement percentile, without bias for gender or the aging process (in other words, you are measured against a specific standard for your age and sex). These percentiles can be interpreted as follows:
My 1.17.55 half marathon P.B. set last year at 50 years old gives me an age adjusted time of 1.10.31 and puts me in National Class :0]
- Over 90% --- World Class
- Over 80% --- National Class
- Over 70% --- Regional Class
- Over 60% --- Local Class
Sounds good but I wonder how true it is ?
