Two Hearted Trail Run

Located in the remote, wild northeastern Upper Peninsula of Michigan, the Two Hearted River captured the imagination of Ernest Hemingway in his novel "The Big Two Hearted River." In addition to world class trout fishing this region features one of the most remarkable stretches of shoreline in the entire Lake Superior basin. Runners in the 50K and Marathon will experience this rugged coastline first hand via single track on high bluffs and more intimate shoreline forests. In addition, the race course winds inland along the shores of Culhane Lake and the Little Two Hearted River. The course is 80% single track and 20% dirt forest road or two track. 

This course has the capacity to transform the way you see nature and the world. The half marathon is a challenging loop that takes runners through old growth white pine forest and along the much loved ridge on the southern shore of Clark Lake. All races finish at the Upper Tahquamenon Falls, second highest east of the Mississippi. Camp 33 Brew Pub is located 200 meters from the finish.
