The Splash and Dash Race is an aquathon consisting of a 1.5km (1-mile) swim and a 5km (3.2-mile) run.

It is a fun, community-focused, grassroots event. There are timing chips; the transition is not fenced in with guards; and spectators, kids, and dogs are encouraged. The swim is in Stevens Creek Reservoir, right outside of Cupertino, CA. The run is on the Stevens Creek Canyon park trails. It is a great way to get intense training in two disciplines or to get open-water swimming practice.
