You ride a bus north in the early light and start near Two Harbors, then spend the morning running back toward Duluth with Lake Superior beside you the whole way. The air coming off the lake stays cool even in June, and the course is mostly gentle rollers with a net 130-foot drop, which is why so many runners chase a personal best here. The finish in Canal Park, beside the ship canal and the old ore boat William A. Irvin, is loud and welcoming, and the seven-hour limit means you are not racing the clock. The hard part is getting in: entries open in early October and the 2027 race is already listed as sold out, with charity spots the remaining option. Book your Duluth lodging the same day you register.
