The Splash Mash Dash Kids Triathlon is perfect for kiddos looking for a way to "TRI" the sport of triathlon or tune up their skills for a larger race. The race will offer kids a safe and fun environment for racing.

To encourage participation and enjoyment for all, The Splash Mash Dash Kids Triathlon is a non-timed event. However, we do have awesome finisher medals that look just like the medals they've seen parents collect over the years! We encourage every child to do their best and practice racing in a supportive environment. We encourage parents to manually time their child if they are interested in a time for their race.
