Le Grizz Ultramarathon & Relay 5K Run

The Le Grizz is a 50-mile Ultramarathon run just to the west of Montana's 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 National Park and surrounded by the changing colors of the aspen and larch. 

The 2024 course is back on the North Fork Road, beginning and ending at the Big Creek Outdoor Education Center (BCOEC). After the 7 am shotgun blast at the BCOEC, runners will head south for 6.5 miles only to turn around where the pavement – and civilization – begins. Runners will then head northbound for 25 miles, summiting Vance Hill before turning around once more to head back to BCOEC for their final 18.5 miles. See maps below for details, and/or click here to view the Strava route.

With approximately 2,300 feet of elevation gain across the 50 miles, this course is remains true to the traditional elevation profile of Le Grizz – undulating gravel roads with occasional gentle inclines – excellent for folks seeking their first ultramarathon finish.
