Age grading uses tables of "age factors" and "age standards" to put all athletes, regardless of age and sex on a level playing field.
Select the event (or enter the distance), enter your details and result, then press Age-grade to lookup the WMA factor. This factor is used to calculate an age-graded result, which can be compared with athletes of different ages.
Also shown are the Open and age-graded standards set by WMA, and from these, your age-performance as a % of the Age std is calculated. This can now be compared between different events.
Pressing Result will calculate your result for a given age-performance - e.g. use your age-performance in one event to predict a different event or the same event at a different age.
Times can be entered as hh:mm:ss.dd - if no colon is supplied it will be taken as seconds; only one colon will be interpreted as mm:ss. The decimal seconds (dd) are not required. Distances and heights can be entered in metres, with or without decimal places.
Decathlon and heptathlon scores (Dec pts) are also calculated from (relevant) results (including age-grading).
This calculator uses the 2006 Age-grading factors (most current) - see: Master's track website. Factors available as Excel file.
