NorthShore Inline Marathon North America's Largest Inline Marathon and Half Marathon 🇺🇸

September 18, 2027 - Duluth, MN. Skate, Run, or Ski the north shore of Lake Superior! Irvin.

The NorthShore Inline Marathon, the largest inline marathon in North America, features the same beautiful point-to-point course as Grandma's Marathon. Beginning just outside of Two Harbors, MN, and running along the scenic North Shore of Lake Superior. There is one difference however, due to the fact that the bricks on Superior Street are NOT skate-friendly, The skaters glide through the 1-35 tunnels at Lemon Drop Hill before entering Canal Park via the 5th Ave. West ramp, and cross the finish line in front of the beautiful and historic William A.
