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 score, 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 - see: Master's track website. Factors available as Excel file.
(The calculator using the previous (1994) factors is still available.)
Explanation for those who wish to use this calculator for race times only.
Age grading is a way of putting all race participants on a level playing field, regardless of age or gender. Age-graded scores let you compare your race times to those of different runners, as well as to the standard for your age and gender.
Your age-graded score is the ratio of the approximate world-record time for your age and gender divided by your actual time.
Age-graded performances have been categorized into these broad achievement levels:
100% = Approximate World Record Level
Over 90% = World Class
Over 80% = National Class
Over 70% = Regional Class
Over 60% = Local Class
Your age-standard result is your finish time adjusted to that of an open division participant using a factor for age and gender. Thus, the times for women and older participants are adjusted downward, while the times for most open division participants (such as 25-year-old men) remain the same.
