What is an age-grouper?

Age-grouper is just another way to say amateur. Anyone who does not have a pro/elite license is considered an age-grouper and they race in events according to age groups, typically separated in five-year increments.

This is the take-off point for all you age-groupers looking for information focused on your interests.


All age-groupers who have done three or more sanctioned triathlons, or two or more duathlons, aquathlons, off-road triathlons or aquabike races are included in the annual age group rankings.
