Marathon Charity Cooperation - Summer Training Program

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.

During the pandemic, the previous board worked tirelessly to keep the tradition alive. Unfortunately, in 2021, they announced they could no longer financially or logically sustain the Reston Triathlon. 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! This year's race date is September 28, 2025.

CORE Foundation is grateful for the loyal athletes and local community. They received overwhelming support while pursuing the opportunity to restore this community event.
