About the Event

The race start/finish is at the Ferdinand St Boat Launch (47.557338, -122.262188) 5018 Lake Washington Blvd. S, Seattle, WA 98118. It runs south with a clockwise loop of scenic Seward Park and back north to the start/finish area. It continues north along Lake Washington through Leschi. The north turnaround is just past the Madrona Drive intersection (47.613496, -122.281265) then you run south back to the start/finish. There are aid stations every 3.1 miles on each loop.

The race is managed and supported by the non-profit NW Ultras which has been the driving force behind the event since 2004. Green Lake Crew has supported the event since 2013. The race is limited to 450 total participants regardless of which event they run.
