Ski North Ultra is an ultra-distance 100K cross-country skiing classic-only event along the North Shore of Lake Superior. The event has 38K and 100K options, following the Norpine, Cascade River State Park and Bally Creek trail systems near Lutsen, MN.
This is a unique cross-country ski event. It is classic-skiing only, and will be on a mix of double-track and single-track ski trails. The trails are incredibly beautiful, and also very technical. State park skiing can mean narrow, sharp turns, and the terrain along Lake Superior can mean long, 20-30 minute climbs, and sharp, steep descents. The 100K race uses advanced courses. The 38K stays on intermediate trails, but please consider if this is the right fit for your skill level. This is a tough course. March snow conditions can be varying, and can also be the most wonderful time of year to enjoy skiing. The event is more of an adventure than a race. Come with an open mind and adventurous spirit, and you will have a great day.
Start and finish in Cascade River State Park. Glide through birch, fir, cedar and pine forests, with overlooks of Lake Superior.
Experience the beauty of the North Shore by ski trail and then keep the vibes going with a post-race celebration. We will have handcrafted prizes from local artists.
Pricing can be a mystery with ski races, so here's exactly what your fees are going toward: 30% coordination/travel, 20% supplies, 10% portapotties, 10% grooming, 10% racer/volunteer gifts, 8% insurance, 7% aid station food and 5% permits. Grants from Visit Cook County, as well as sponsors - Finn Sisu, Pointed Home Real Estate - cover post-race food at Cascade Restaurant, Norpine membership, awards, transportation (thank you Finn Sisu van!), bibs, wax support, misc supplies (Tailwind, cardamom rolls) and additional aid station food.
Price discounts and student pricing available. Please email rykken44@gmail.com for more info.
The What-Ifs: Courses may be subject to change based on snow conditions, and will be made in the best interest of the participant's safety and overall experience. In the case of extreme temperatures or conditions, we may adjust the start times and distances. The goal will be to put on the best race possible with the factors we are given. Partial refunds may be available in the case of a cancellation. Thanks for understanding it's all a bit of a gamble!
Refund policy: Full refunds can be offered up to two weeks after registration. Partial refunds can be offered up to four weeks after registration, and beyond that, unfortunately, we can't offer refunds.
Cut-off Times: In the interest of volunteers' time and keeping everyone to mostly daylight hours, we will have a cut-off time of 12 hours for the 100K.
Safety: There are inherent risks in any endurance event, but please note the following:
• Conditions are subject to change throughout the day.
• Aid Stations may have distances up to 20 km between them and some may be self-served.
• ROAD CROSSINGS: Skiers will need to cross roads during the race, and will be fully responsible for watching for any on-coming vehicles and making their own decisions upon when to cross. Do NOT assume cars will stop for you.
• There are two-way sections in which you will need to be cautious of other skiers and stay to the right side of the trail.
• The trails will be open to the public, so please be mindful of other trail users.
Aid Stations: Aid Stations will largely be run by volunteers. Many have limited parking and limited cell service. You can expect water, energy drink, first aid and a variety of food/fuel options. Please plan to carry your own beverage containers.
The Great Minnesota Ski Pass: We get to ski on wonderful State Park and National Forest Service lands. Thank you to all who currently and have historically cared for this incredible area. All racers should have a Great MN Ski Pass ($10 Day Pass or $25 Season Pass), which gives you access to all state park and state forest ski trails. Please also remember to buy a State Park parking pass if you choose to park inside Cascade River State Park. Thank you!
This event is operated under a special use permit on the Superior National Forest.
We are so thankful to our supporters, and in particular, Visit Cook County, for providing assistance with marketing, local food, and local artisan prizes this year. Thank you for being a fantastic resource.
