Runners in the half marathon follow a 13.1-mile route through the Beaverhead Deerlodge National Forest in Montana’s southwestern corner, from the starting line at the base of Black Butte Mountain. Along the way, runners follow Gravelly Range Road (also known as National Forest Service Road 290) all the way to the race finish line at the Clover Meadows Campground, which lies about a 35-mile drive from downtown Ennis.
