Grand Ridge Trail Runs

The Grand Ridge Trail Runs take place at Grand Ridge Park near Issaquah, Washington, with a course suited to athletes of every level. The park's extensive trail network, developed by the Washington Trails Association, winds through lush forest in the foothills of the Cascades, past rain-fed ferns, moss-covered trees, and striking golden fall foliage that make for both scenic beauty and a genuine physical challenge. Trails are well-graded, but expect demanding climbs that test your endurance and strength.

Distances range from a 1-mile fun run to 5K, half marathon (13.1 miles), marathon (26.2 miles), and 50K (31 miles). The race is organized by Evergreen Trail Runs, founded by athletes for athletes, which has put on trail races across Washington State since its start. As a sister brand of Orca Running, it remains focused on delivering high-quality, community-driven trail race experiences.
