Get ready for an aquathon adventure in Cupertino this Thursday afternoon! Adults will tackle a 1.5km swim in Stevens Creek Reservoir followed by a 5km run through Stevens Creek Canyon Park trails, while youth competitors (ages 11-15) complete a 200m swim and 2km run. This community-driven event features chip timing, an open transition area, and welcomes spectators, kids, and dogs—making it perfect whether you're looking for an intense two-sport challenge or valuable open water swimming experience.
