Content: For the men's marathon, athletes are considered seniors if they are aged 19 to 31; for the women's marathon, it's 20 to 30. All track events for both males and females have a senior age range of 22 to 31. Runners of ages above and below the range for senior athletes are considered at a disadvantage, and this is taken into account when determining their age-grading percentages. Open-class-standard
The open-class-standard is the time for the specified distance and sex that will result in an age-grading percentage of 100% for a senior athlete. The open-class-standard can be thought of as the fastest possible time for a distance by an athlete of a specified sex. Age-standard
The age-standard time is derived from the open-class-standard, and is the time for a specified distance and sex that will result in an age-grading percentage of 100% for an athlete of the specified age. It can be thought of as the fastest possible time for a distance by an athlete of a specified age and sex. Age-factor
The age-factor is used to calculate the age standard from the open-class standard. It is a value equal to 1 or less.
