TRi KiDS Race Distances

YEAR OF BIRTH is used to place athletes in the appropriate age group.  The athlete’s age on race day is not used for age group assignment. As an example, all athletes turning 8 in 2019, whether their birthday is in January or December,  will be placed in the 8-9 age group. If you feel your child is not ready to be in the age category based on this criteria please contact us by email prior to registering.

See Age Group Assignments page.

Athletes start off with a swim in the indoor (and outdoor) pool, transition to the bike and then head off on the run course. All that’s required is a swim suit, a bike in good working order, a helmet and running shoes.  Visit and review our Race Details and Rules for Safety page for more information.
