UW Medicine Seattle Marathon and Half Marathon
Join UW Medicine Seattle Marathon and Half Marathon 2025
From its humble beginnings in 1970 when a group of friends from the University of Washington decided to hold their own marathon, the Seattle Marathon has grown into one of the largest combination marathon/half marathons in the Northwest.
That first marathon 54 years ago sported less than 30 runners. This year, thousands of participants are expected for the marathon and half marathon walking and running events.
The course begins at 5th Avenue at Harrison Street, in front of the Museum of Pop Culture. Participants travel through downtown and along Seattle's iconic bridges, waterways and neighborhoods. The course is USATF certified and serves as a Boston qualifier and a World Marathon Majors qualifying event.
Join us the Sunday after Thanksgiving (US) for Seattle's Original Hometown Marathon.
