Since 1984, the Reston Triathlon has been a staple in our community. It opens with a 1500-meter open water swim in Lake Audubon, followed by a 25-mile bike ride and a 10K run on local paths. The Olympic distance event has challenged athletes from around the country and has affectionately been called the Reston Triathlon World Championship.

A Brief History

During the pandemic, the Reston Triathlon Board of Directors worked tirelessly to keep the tradition alive. Unfortunately, in 2021, they announced they could no longer financially or logically sustain the beloved race. CORE Foundation, working closely with the previous board, is thrilled to revive the event and continue the legacy. The Reston Triathlon made its comeback debut on September 10, 2023, and is held annually on the Sunday after Labor Day.

CORE Foundation is grateful for the loyal athletes and strong community. They received overwhelming support while pursuing the opportunity to restore this local event. CORE Foundation and Racing in Reston appreciate your continued support as they maintain and improve this race well into the future!
