Course Map

New for 2013, we are changing the direction of the run

Parking and Start will be at Marymoor Park, while the Finish will be at Lake Sammamish State Park, where shuttles will wait to take you back to your car (shuttles are included in entry fee). If you have family/friends that want to cheer you on or pick you up at the finish, there is plenty of parking at Lake Sammamish State Park, but a Discover Pass is required for access of the park.
