Grandma’s Marathon is a premier road race along Lake Superior’s North Shore in Duluth, Minnesota, taking place on June 20, 2026. As the 50th annual edition, it offers racers a fast, scenic point‑to‑point course from Two Harbors to Duluth, culminating in an iconic finish beneath the Aerial Lift Bridge in Canal Park. With net downhill terrain and rolling hills, it’s both beginner-friendly and Boston‑qualifying. The weekend also features a half‑marathon (Garry Bjorklund Half), William A. Irvin 5K, and the Great Grandma’s Challenge. Packet pickup and expo begin June 18–19 at DECC. Expect festive crowds, live music, local food, volunteer support, and lakeside charm. Whether you're targeting a Boston‑qualifying time or soaking in Minnesota’s summer beauty, Grandma’s Marathon delivers an unforgettable running experience.
