Welcome to the
Orange County Kids Triathlon
Information & Registration Site
Thank you to all our OC Kids Tri Participants and Fans, 

We want to let you know that due to construction at Costa Mesa High School
we will be taking a one year hiatus from the Triathlon but plan to be back next year, 
even bigger and better!  Please check back next Spring for information regarding our 2016 Tri! 

Thank you again for your participation and support.  We hope to see you at our event next year!


The OC Kids Tri course is great for athletes new to the sport and provides a competitive sprint course for the more experienced.  It was designed to allow visibility and easy access for friends and family to cheer on their triathletes.


We will have kick boards available for our less than confident swimmers.

We pride ourselves on running a safe, fun, and challenging event.  Along with providing a clearly marked course, we will have plenty of volunteers along the course to assist if needed.

  • Run is flat. All areas easily accessible and visible for cheering on the athletes.
  • Cycling will remain within a closed course, entirely on paved roads.  Long course consists of two full laps. 
  • Swim takes place in a new Olympic size pool located at the CMAC (Costa Mesa Aquatics Center) on the property of Costa Mesa High School. 

If you are a beginner, this race is an excellent way to introduce you to the sport of triathlon.  If you’re a triathlete veteran, come test yourself on our closed course!
