The NorthShore Inline Marathon, Inc. is a 501(c)(3) Minnesota non-profit corporation incorporated on August 27, 1996. The primary purpose of the NorthShore Inline Marathon, Inc. is to foster national and international amateur in-line skating competition and to promote health and fitness throughout the organization, promotion, development and conduct of a recreational in-line skating marathon.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 differnce however, due to the fact that the bricks on Superior Street are NOT skate-friendly. The skaters duck into 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. Irvin. Rollerskiers have an alternative finish line on Railroad Street, due to the last 1/8th mile being concrete.
