“All Skaters Welcome on the North Shore”
World Inline Cup is the premier international circuit for inline marathon racing, uniting the world’s top events under one global series. The WIC brings together elite and professional skaters from across Europe, North America, South America, and beyond, creating a competitive calendar that spans multiple countries and continents each season. The World Inline Cup serves as the sport’s global benchmark and a meeting point for the very best in long distance inline skating.
The NorthShore Inline Marathon features four unique inline skating races, giving athletes of all levels a chance to experience one of the most scenic courses in the country. Skaters can choose from the full marathon, half marathon, 10k, or combined events. Every race follows portions of the iconic North Shore route along Lake Superior and includes a signature moment that makes this event truly memorable. Participants roll down a fully closed section of I-35 and glide through the Duluth tunnels, creating an experience that is hard to find anywhere else.
The NorthShore Inline Marathon weekend offers four exciting inline races designed for skaters of all experience levels. Each event gives participants a chance to enjoy Lake Superior views, smooth pavement, and a professionally organized weekend that brings thousands of athletes to Duluth. The course is known for being fast and rewarding, which makes it a great option for both first time skaters and those preparing for larger national events. It is an energizing, memorable way to experience Duluth and be part of one of the most iconic inline races in the country.
“one of the most unforgettable race courses I’ve ever skated”
The NorthShore Inline Marathon offers four exciting ways for skaters to experience the beauty of Duluth. The full and half marathon events follow the iconic point to point course along the North Shore, featuring gentle elevation, long views of Lake Superior, and a smooth finish as skaters enter the city and approach the lakefront. The 10k gives participants a shorter but fast paced option, complete with the unique experience of skating through the Duluth tunnels on a closed section of I 35. Every course showcases the scenery, energy, and welcoming atmosphere that make skating in Duluth one of a kind. Get a full description below:

It is the best race for families. My three kids and I have been doing this race for years and we love the community. Everyone is so happy and welcoming, and we could not ask for a better location. The atmosphere is upbeat from start to finish and there is always something fun happening. It has become a tradition we look forward to every year and a chance for all of us to enjoy the day together.
This is North America’s largest inline marathon for a reason! What a great day full of fun events. The course has been in outstanding shape. There is literally an event for EVERYBODY of any age or experience!
I have traveled over 262 miles on this beautiful stretch over the last 10 years. I hope to tack on another 26.2 each and every year until I no longer can. Honestly one of the coolest events that the upper Midwest has to offer.
