The Le Grizz Ultramarathon & Relay is a historic running event that has been a staple in Polebridge, Montana, since 1982. This classic race, one of the oldest 50-mile footraces in the United States, takes runners on a scenic journey along a gravel road that parallels the North Fork of the Flathead River, offering breathtaking views of Glacier National Park. The event includes a challenging 50-mile ultramarathon, a team-based 50-mile relay, a 15K run, and a 5K fun run, ensuring there's an option for every level of runner. Beyond the competition, the race fosters a strong sense of community, culminating in a post-race celebration with a fried chicken picnic and the famous huckleberry bear claws from the Polebridge Mercantile.
