Chelanathon Manson, WA   Sep 19, 2026

Ready for a racecation? Enjoy beautiful Lake Chelan and compete in one of the most scenic triathlons in the PNW. Crystal clear waters (with an underwater lane line!!), bike course through vineyards and orchards, and then a run through the heart of historic downtown Manson.

Building on the success of the inaugural Olympic, Olympic Relay, and Sprint Triathlons, Chelanathon is expanding the race lineup to include an Aqua-Bike, 10k run and Kids Splash & Dash.

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 makes this event unforgettable.

After you cross the finish line, your day (and your weekend) are just getting started. Kick back and enjoy everything Manson and Lake Chelan have to offer — world-class wineries, farm-to-table dining, boat rentals, paddleboarding, hiking, shopping, and more.
