Grandma's Marathon

Founded in 1977, Grandma's Marathon has grown into one of the Upper Midwest's most celebrated summer road races, drawing elite competitors and thousands of recreational runners from across the U.S. and abroad. Traditionally run in June, the event retains a community-focused, festive atmosphere with strong volunteer support, live bands, and finish-line celebrations that showcase Duluth's lakeside charm. The race's name and spirit reflect its local roots and long history as a marquee destination marathon in the region. The point-to-point course begins in Two Harbors and follows scenic Highway 61 along the North Shore of Lake Superior before descending into Duluth, offering sweeping lake views, rocky shoreline vistas, and a mix of rolling terrain that rewards smart pacing. Runners experience iconic landmarks such as the Lakewalk and Canal Park in the final miles, finishing with a memorable approach beneath the Aerial Lift Bridge on Duluth's waterfront. Aid stations, crowd support, and well-organized logistics make the route both picturesque and race-ready for fast times or personal-first marathon experiences. Grandma's Marathon is USATF-certified and serves as a Boston Marathon qualifying course, making it popular among athletes seeking qualifying times as well as those chasing a scenic summertime marathon. The event's combination of storied history, stunning lakefront scenery, and energetic local support creates an approachable yet competitive race experience for a wide range of runners.
