Get ready to tackle 50 miles of gorgeous gravel road running just west of Glacier National Park, where you'll be treated to stunning views of the Crown of the Continent and the vibrant fall colors of aspen and larch forests along the North Fork of the Flathead River. This out-and-back adventure starts and finishes at the Glacier Institute's Big Creek Outdoor Education Center, takes you past Red Meadow Creek, and includes a pit stop at the iconic Polebridge Mercantile aid station. With about 2,300 feet of elevation gain spread across the course, you'll experience the classic Le Grizz challenge that runners love.
