The NorthShore Inline Marathon, hosted each September along the breathtaking shores of Lake Superior from Two Harbors to Duluth, is a premier multi-sport endurance event and community celebration. While it is best known as the world’s largest point-to-point inline skating race, the festival also highlights an impressive running program with the Aspirus St. Luke’s Half Marathon and the Finden Marketing Tunnel 10K Run, attracting runners of all levels. Inline skaters can choose from the full marathon, half marathon, Tunnel 10K, or the challenging 39.3-mile combined skate, while rollerskiers test themselves in the full and half marathon events. Families and youth are included in the excitement with free kids’ sprints, and the weekend also features an expo, community gatherings, and scenic racing through iconic Duluth landmarks like the I-35 tunnels. Together, these events make the NorthShore Inline Marathon & Skate Fest a one-of-a-kind celebration of fitness, endurance, and the North Shore spirit.
