NorthShore Inline Marathon

NorthShore Inline Marathon is North America’s largest point-to-point inline marathon and a major Duluth race weekend for inline skaters, half-marathon skaters, 10K skaters, combined-distance athletes, and rollerskiers.

The official site lists the 2026 race date as September 19 and describes a scenic Lake Superior course with smooth pavement, a closed I-35 section, Duluth tunnel experience, and an iconic Canal Park finish. It is also listed as a World Inline Cup event, giving the page both recreational and elite-racing relevance.
