Skagit Flats Marathon & Half Marathon

Sunday, October 1, 2023 • Burlington, WA • Course Map

Nestled among the berry farms, tulip fields and waterfront communities of Washington State’s Skagit Valley, Burlington plays host each fall to the Skagit Flats Marathon & Half Marathon, a fast and flat race event that takes runners on an out-and-back course through beautiful rural countryside.

USATF-certified and a qualifying race for the Boston Marathon, the Skagit Flats races start and finish at Edison High School, and are run along rural roads through area farmland to the entrance of nearby Samish Island and back.

Out on the course, don’t be surprised if you spot birds of prey — the Skagit Valley is reputedly one of the state’s best viewing areas for the birds, from bald eagles to hawks to peregrine falcons, who migrate to the area each winter.

Participants (the event is open to both runners and walkers) will have six hours to complete either the full or the half marathon, and race organizers say those who have not finished by 2:00 PM will “be responsible for their own safety,” as roads along the race course will be re-opened after 2:00.
