The NSIM Half Marathon Race is a great option for younger rollerskiers, recreational rollerskiers, or rollerskiers who want to experience the fun and excitement of a world class event without going the full marathon distance. The Half Marathon has the same charm and glory as the Full Marathon. It starts at the north end of Duluth and rolls along Scenic Highway 61 and the glimmering shores of Lake Superior on the famous Scenic Highway, taking participants through the two famous I-35 tunnels, and finishes with amazing views of the Aerial Lift Bridge and the Duluth Harbor. Bring your friends and teammates to Duluth this September for the NSIM Half Marathon Rollerski Race.
