2026 Seattle Ghost Marathon, Half & 50K

Get ready to hit the ground running at the 41st Seattle Ghost Marathon on November 28, 2026! What started in 1985 as a course change for the Seattle Marathon has now become an iconic race, which also serves as a flat and speedy Boston Marathon qualifier. Picture yourself looping twice around the breathtaking Lake Washington, starting and ending at the Ferdinand St Boat Launch, with the vibrant support of local communities and aid stations to keep you going every 3.1 miles.

As a participant, you'll not only challenge yourself but also contribute to the passionate efforts of NW Ultras, the nonprofit that's been fueling this event since 2004, along with the support of the Green Lake Crew since 2013. Remember, the field is capped at 450 runners to keep the experience intimate and impactful, so secure your spot fast! Race day is also your packet pick-up day, and while your furry friends and strollers must sit this one out, the memories you'll make will last a lifetime!
