Runners in the November half marathon — like those in the full marathon, 5-Mile and 50K runs — follow an out-and-back route that starts and finishes just off Exit 20 from Interstate 90, roughly 20 minutes east of downtown Seattle, and just east of the Issaquah Highlands residential development. Entrants are asked to park along the road just off the exit, where the starting line lies just a short walk from the parking lot. Organizers say the trails are single-track and “fairly wide,” so passing other runners along the trail “should not be an issue.”
