Age Grading...I am an athlete...

received this information together with the AMA HM Championships results:

"AGE GRADING – how it works

Age grading uses tables of “age factors” and age standards to put all runners regardless of age and sex on a level playing field. In particular, they allow runners’ performances, no matter what their age, to be corrected to what they would have been achieving in their prime years, and permit valid comparisons to be made between people of different ages.

The tables also provide each individual with a percentage value for an event, allowing them to judge their performance against the standard for their age both now, and keep track of their progress over time

Relative Standard Indicator:

> 0% = An Athlete
> 70% = Regional class
> 80% = National Class
> 90% = World Class
>100% = World record level"
