Glacier Ridge Trail Ultramarathons and Trail Race
May 14, 2016 @ 5:00 am - 8:30 pm
Trail courses (including 5-person relay) are out-and-back style courses. The 30K and 50K courses largely follow the blue-blazed Glacier Ridge Trail (GRT)/North Country Trail between Moraine State Park and Jennings Environmental Education Center. The 50-mile course uses the GRT, as well as a system of snowmobile/horse trails to the east of Lake Arthur.
