The NorthShore Inline Marathon is proud to offer races for cross country skiers with our two unique roller ski races. Our 42k and 21k offer a beautiful route along Lake Superior. The NSIM roller ski races navigate the scenic north shore drive. Roller skiers take a turn while entering Duluth, where they get the experience of roller skiing on Highway 61 and I-35. Join one of the largest roller ski races of its kind. Grab your roller skis, boots and poles and take part in a beautiful race along the North Shore. Compete against some of the top skiers in North America, or grab some buddies and ski with friends. Our races are perfect for all ranges of abilities. Ski the beautiful scenic route on the North Shore while you gear up for winter.
NorthShore Rollerski Events
NorthShore Ski 42k
42 Kilometers | point-to-point
Our 42-kilometer option is the classic “ski marathon.” Starting in Two Harbors, Minnesota, this race takes you along the shores of Lake Superior on the beautiful Scenic Highway. As you get closer to Duluth, the landscape changes, and the fans on the side of the road become more plentiful. Ski the famous I-35 tunnels, From there, finish with an outstanding view of the Aerial Lift Bridge. Join us at the nation's premier marathon rollerski race.
NorthShore Ski 21k
21 Kilometers | point-to-point
This race is a great option for younger rollerskiers, more recreational rollerskiers, or skiers who are not looking for marathon distance competition. The 21K is race starts at the halfway mark of the 42k option, but still has the same charm. Racers still get to ski along the shores of Lake Superior on the famous Scenic Highway and I-35 tunnels. The finish line is the same as the 42k, with amazing views of the Aerial Lift Bridge that Duluth is so famous for.

Our Lodging Partners:
Flying to Duluth or Minneapolis
The Duluth International Airport offers great flight packages from anyone coming from across the country. This is our recommended route for anyone who plans to fly to our event. We then recommend renting a car, taking an uber/taxi, or calling your hotel shuttle to pick you up.
If the Duluth International Airport may not meet your needs, the Minneapolis-St. Paul International Airport (MSP) is another great option. Located just over two hours south of Duluth, MSP offers a wide variety of flights and is one of the largest airport hubs in the midwest. For more information on MSP check out their website here: MSP International Airport
Transportation from MSP/Minneapolis to Duluth
Being the largest inline marathon in North America draws crowds from across the country. Many participants come from out of state. Because of that, the NorthShore Inline Marathon has created a partnership with our local bussing company that will pick you up from the MSP Airport and brings you to Duluth.
