The Glacier Ridge Trail race features an out-and-back layout for its 30K and 50K courses, primarily traversing the blue-blazed Glacier Ridge/North Country Trail. This scenic route stretches from the western edge of Moraine State Park to the Jennings Environmental Education Center near Slippery Rock, PA. Runners may see markers for the North Country Trail along the course, as they represent the same path. The 50-mile course expands upon the GRT, incorporating additional snowmobile and horse trails located east of Lake Arthur, offering a diverse running experience. Participants should be prepared for a challenging course that showcases the natural beauty of the region while testing their endurance.
