A Splash and Dash is a fun and fast-growing sport that combines running and swimming, and focused on focused on fun and participation over competition. OTC wants to introduce kids and families to how
great the multisport life is through this USAT sanctioned event!
We celebrate participation!
For our regular Super Sprints, timing will be unofficial, and everyone wins for the regular Super Sprints. Kids of any age can choose Super Sprint x1 or Super Sprint x2.
And back from 2025, kids can choose to do the Super Sprint x2 competitive event - which will count towards the USAT Northern California Youth Series!
We will have volunteers around supporting safety and fun, making sure kid take breaks mid-swim if need -- and that they catch their breath before heading on towards the run course. Every competitor will be celebrated as they cross the finish line and will go home with an NEW FOR 2026 official USAT Splash and Dash medal, or a custom competitive wave medal.
Come on out and join the fun!
