About the Stonetown Triathlon 

The Stonetown Triathlon, organized by the Balance Point Triathlon Club, offers thrilling races for youth aged 8-19. In addition to competitive drafting races for older athletes, it includes recreational and non-drafting events for younger participants.

A triathlon combines swimming, biking, and running into one continuous event, with distances tailored to age groups. Athletes wear timing chips to track their race, and results are posted online. Spectators are encouraged to cheer from the sidelines.
