The Glacier Ridge Trail 50K and 50 Mile Ultramarathons and 30K Trail Races are out-and-back style courses. The 30K and 50K courses largely follow the blue-blazed Glacier Ridge/North Country Trail between the west end of Moraine State Park and the Jennings Environmental Education Center near Slippery Rock, PA. The Glacier Ridge Trail (GRT) is part of the more extensive North Country Trail system that passes through Moraine State Park. The 50-mile course uses the GRT, as well as a system of snowmobile/horse trails to the east of Lake Arthur.
The 2013 event drew a crowd of 270 runners.
