Skagit Flats Marathon, Half & 5k

Lace up for the Skagit Flats Marathon, Half & 5k on September 13, 2026, in Burlington, WA, a race renowned as the flattest Boston Qualifier in Washington state. This event, now in its 49th year, offers marathon (26.2M), half marathon (13.1M), and 5k (3.1M) distances, promising a fast and incredibly flat course ideal for personal records. The rural out-and-back route guides runners through the picturesque Skagit Valley farmlands, with minimal elevation changes, often cited as less than 10 feet for the entire marathon. Typical race day conditions in mid-September feature pleasant highs around 70°F and lows around 51°F, with a modest 12% chance of precipitation.

Runners can anticipate plentiful, full-service aid stations staffed by enthusiastic local cross-country teams, offering water, FLUID Performance sports drink, and Honey Stinger Gels, with additional water-only stations at key marathon turnaround points. While the scenery primarily consists of expansive farm fields, the supportive volunteers create a welcoming atmosphere throughout the course. The race begins on Victoria Street, south of Burlington Edison High School, and culminates with an exciting finish on the high school's track.

The Skagit Flats Marathon is celebrated for its excellent organization, managing a participant cap of 800 to maintain a small-town race feel. After crossing the finish line, all runners receive a finisher's medal and can enjoy post-race food and convenient access to showers and changing facilities in the high school locker rooms. Be prepared for exposure to sun and potential wind on this open course, but know you're running on a USATF-certified route designed to favor roads with less traffic, making it a prime opportunity to achieve your running goals.
