Grandma’s Marathon & Kids Races

Grandma’s Marathon, often affectionately referred to as simply “Grandma’s,” is a pinnacle event in the running community, set against the breathtaking backdrop of Lake Superior in Duluth and Two Harbors, Minnesota. This 49th annual iteration, taking place from June 19 to 21, 2025, is more than just a marathon; it’s a celebration of endurance, community, and natural beauty.

At its core, Grandma’s Marathon is for athletes, particularly runners who thrive on the challenge of a 26.2-mile course. However, the event also warmly welcomes families, spectators, and anyone drawn to the vibrant atmosphere that permeates the entire weekend. The target audience includes seasoned marathon runners, first-time participants, and enthusiastic supporters who line the streets to cheer on the athletes. Notable guests often include local running legends, Olympic athletes, and motivational speakers who add to the event’s inspiration and camaraderie.

The event unfolds over three days, starting with the William A. Irvin 5K on Friday evening, June 20, 2025. This 5K sets the stage for the main events on Saturday, June 21, which include Grandma’s Marathon and the Garry Bjorklund Half Marathon. The day begins early, with the marathon starting at 7:45 AM CDT and the half marathon following shortly after. The festivities continue into the evening with awards ceremonies, live music, and a sense of community that bonds participants and spectators alike.

The marathon course itself is a picturesque point-to-point route that begins north of Duluth near Two Harbors and follows Scenic Highway 61 along the shores of Lake Superior. Runners pass through rolling hills and enjoy a net downhill elevation as they make their way through the heart of downtown Duluth, finally finishing in the historic Canal Park. This setting is not just a venue but a natural amphitheater, with Lake Superior’s vast expanse and the city’s scenic landscapes providing a stunning backdrop for the entire event.

Attendees can reach Duluth via the Duluth International Airport or by driving along Interstate 35. Local transportation and shuttle services are also available to facilitate travel between event locations. For those arriving by boat, access to the marina near Canal Park offers a unique perspective on the festivities.

What makes Grandma’s Marathon unique is its blend of athletic challenge and community spirit. The event is marked by the iconic yellow balloons that denote each mile, and participants are cheered on by an energetic crowd that lines the streets. The Great Grandma’s Challenge, which includes both the 5K and either the marathon or half marathon, adds an extra layer of excitement for those seeking an extended test of endurance.

Beyond the races, the event offers a rich tapestry of experiences. Live music performances, though not on a floating stage, still resonate through the air as runners cross the finish line and spectators celebrate. Local vendors and food stalls offer a taste of Duluth’s culinary scene, with everything from traditional Minnesota fare to international cuisine. The finisher medals and specialized Challenge medals serve as tangible reminders of the achievement and camaraderie shared over the weekend.

Grandma’s Marathon is not just an event; it’s an experience that combines the raw beauty of Lake Superior’s shoreline, the resilience of human spirit, and the warm hospitality of the Duluth community. Whether you’re a seasoned athlete, a supportive family member, or simply a spectator drawn to the energy, Grandma’s Marathon offers a weekend that is both inspiring and unforgettable.
