Chuckanut 50k
The Chuckanut 50k is an ultra endurance trail race based in Fairhaven, Washington, organized by Runner Girl Races, LLC. The event uses a lollipop course that begins and ends with 10k on the Interurban Trail, offering smoother running at the start and finish. The central section covers about 30k along Chuckanut Mountain Ridge and includes sustained climbing, a total ascent of about 5,000 ft, ridge traverses, and technical singletrack that exposes runners to variable weather and Pacific Northwest terrain.
Support materials and route information are provided as maps, course videos, and virtual GPX files. Registration and race results are hosted through Pacific MultiSports. The event is sanctioned through USAT&F and the organizers apply for event insurance.
The race program also includes a kids race consisting of 1/2 mile loops within a 30 minute window. Other event features listed by the organizer include awards, coaching options, volunteer coordination, hotel partners, photo galleries, and historical race results. A livestream of race day was made available for 2026 under the Mountain Outpost banner. The organizing company has been a member of the Conservation Alliance since 2010.
