Since its inception in 1970, when a group of friends from the University of Washington organized an informal marathon to challenge themselves and celebrate their love for running, the Seattle Marathon has evolved into one of the premier long-distance events in the Pacific Northwest. Starting with fewer than thirty runners that inaugural year, today's race attracts thousands of participants eager to experience its scenic routes. The event kicks off on a historic note at 5th Avenue and Harrison Street, directly in front of the Museum of Pop Culture. From there, athletes embark on an adventure through downtown Seattle, crossing iconic bridges like the Aurora Bridge and the Montlake Bridge while enjoying breathtaking views of Lake Union and Puget Sound. The course winds its way past vibrant neighborhoods such as Capitol Hill and Queen Anne before concluding at Memorial Stadium in Montlake. Certified by USA Track & Field (USATF), this race is recognized both nationally and internationally, serving not only as a Boston Marathon qualifier but also contributing to the World Marathon Majors qualification criteria. Whether you're aiming for personal best times or simply looking to immerse yourself in Seattle's dynamic urban landscape, the Seattle Marathon offers an unforgettable experience. Mark your calendars for the Sunday following Thanksgiving Day (US) and join us for what is truly Seattle’s Original Hometown Marathon – a celebration of community spirit and athletic achievement.
