Course and terrain
The 50-mile event is run on gravel road that parallels the North Fork of the Flathead River, just west of Glacier National Park. The course provides views of the Crown of the Continent region and runs through areas with aspen and larch trees. Runners can generally expect approximately 2,300 feet of elevation gain across the 50 miles. The route is described as undulating gravel roads with occasional gentle inclines. The organizer notes that road construction on the North Fork Road has required course re-routes in recent years, so the exact course may change.
