One More Splash of Summer

Saturday, August 21, 2027 · The Penllyn Club

End the summer with a swim, a ride and a run! Kids Rock Endless Summer is a fun, non-competitive triathlon and duathlon for kids ages 5–15 — built especially for first-timers, with lifeguards in the pool and friendly crew all over the course.

Limited to 200 athletes. Once we hit 200, registration closes — no exceptions.
