You asked for it — and we’ve answered.
Building on the success of our inaugural Olympic, Olympic Relay, and Sprint Triathlons, Chelanathon 2026 is expanding the race lineup to include a 10K, 5K, and Sprint Triathlon Relay.
Whether you’re chasing a PR, racing with friends, or just looking to soak up the Lake Chelan views, there’s a perfect distance waiting for you. From first-timers to seasoned athletes, every course captures the same community spirit, local support, and lakeside energy that made last year’s event unforgettable.
Pick your distance, set your goal, and join us September 19, 2026 — where every race is a reason to celebrate.
