Known officially as the Garry Bjorklund Half Marathon, the 13.1-mile race at the Grandma’s Marathon starts a few blocks north of Clearwater Grille overlooking Lake Superior, at the mid-way point of the full marathon route. From there, it follows the exact same course all the way along the shoreline of the lake to the race finish line in Duluth’s Canal Park, along Canal Park Drive.
