The Seattle Marathon Association (SMA) is a non profit organization governed by a ten member Board of Directors. It is proud of its commitment to providing a quality running event in the Pacific Northwest, providing our sponsors with maximum exposure in association with the event and making a positive social and economic impact on the city of Seattle. Using the Visitors and Convention Bureau Statistics, a conservative positive economic impact to the Seattle economy is five million dollars per year. With the current growth trend of the Seattle Marathon, the economic impact could double within three years.  

Our Mission: To produce an annual Seattle Marathon event, the quality of which is a credit to our sponsors and the communities we serve. We encourage participation by runners, walkers and volunteers of all skill levels.
