Green River Marathon 2027

The Green River Marathon is scheduled for June 5, 2027 and is listed as the 31st annual running of the event. The program for 2027 includes multiple distance options and a relay format.

The event offers these distances:

  • Marathon
  • Half Marathon
  • 50K
  • Relay

Race operations have included at least one aid station located 6.55 miles from the start. Entry and results procedures have required organizers to collect participant details; relay teams provide a team name and participant names for the results listing. For solo runners the organizer has requested basic entry information including name, city and state, date of birth, age on race day, sex, best previous time and a predicted time.

The course has been run in different formats in recent years, and organizers have noted a possibility of returning to an original route that ends in Alki, though the route may vary by year. Results and past race pages are maintained by the event organizers and have been published for previous editions. Visit the organization's website for the most recent information.
