About This Race

The 5-mile option welcomes newcomers to trail running and provides a family-friendly distance for the Grand Ridge celebration. This shorter course focuses on the joy of running on natural surfaces without the intimidation factor of longer distances. Perfect for first-time trail runners or those looking for a spirited workout, the route delivers an authentic trail experience in a manageable package.

The race utilizes two distinct loops: a 5-mile loop and a longer half-marathon loop of approximately 14 miles. All distances begin at the Highpoint Way Trailhead, following the Issaquah-Preston Trail for 0.5 miles before ascending rocky, technical switchbacks to the course junction. The longer distances continue up Grand Ridge with a detour to the Flowing Fir Trail before reaching the Duthie Aid Station. Marathon runners complete two half-marathon loops, while 50K runners tackle two half-marathon loops plus the 5-mile loop. The trails remain open to other users including pedestrians and cyclists during the event.
