About the Event

Le Grizz is a 50-mile Ultramarathon run just to the west of Montana's Glacier National Park on a gravel road that parallels the North Fork of the Flathead River. Runners will find themselves gaining views of the magnificent Crown of the Continent, made up of Northern Rockies of Southern British Columbia and Glacier Park, and surrounded by the changing colors of the aspen and larch. 

The 2026 course is an out-and-back route which will begin and end at the Glacier Institute's Big Creek Outdoor Education Center, following the North Fork Road just beyond Red Meadow Creek, with a brief detour into our Polebridge Mercantile aid station. 

The course contains approximately 2,300 feet of elevation gain across the 50 miles – metrics that are true to the traditional elevation profile of Le Grizz from the legacy Spotted Bear course. The road is undulating gravel with occasional gentle inclines – excellent for folks seeking their first ultramarathon finish.

Ready to test your limits? The Le Grizz Ultramarathon & Relay brings a highly anticipated Ultra, 15K, 5K to Polebridge on October 10, 2026. Expect a fantastic route right in the heart of Montana.
