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 Family of Events has grown into one of the largest combination marathon/half marathon in the Northwest. That first marathon 49 years ago sported less than 30 runners. This year, 8,000 participants are expected for the marathon and half marathon walking and running events. Join us the Sunday after Thanksgiving for Seattle's Original Hometown Marathon
