A scenic 50-mile event (point-to-point on a rolling forest road) near Glacier National Park in Hungry Horse Reservoir, Montana.

Since 1982, the Le Grizz 50-mile Ultramarathon has commenced every autumn on the second Saturday of October. For the past 33 years, upwards of 100 runners have stood half awake on the frozen ground near Spotted Bear Ranger Station alongside the Hungry Horse Reservoir, waiting anxiously for a ceremonial shotgun blast to signify the start of one of the oldest 50-mile footraces in the world, and the first in Montana.
