Sunnyvale Kids Splash & Dash

Nice introductory event for youth triathletes.
Event consists of a swim and run combination where the athletes have to go through the transition while changing sports.

"Splash and Dash races are a fun, fast-growing variant of aquathlons for youth athletes that combine swimming and running. Timing is not required during Splash and Dash races, putting the focus on participation rather than competition.

With less equipment required and a great opportunity to meet friends and other young athletes, Splash and Dash races are the perfect introduction for youngsters to the world of multisport."
