Run The North Shore's
Premier Fall Races

St. Luke's Wheels Off Half Marathon
Tunnel 10k Run

September 16th, 2023 | Duluth, Minnesota

The NorthShore Inline Marathon is proud to offer non-skating races with our two unique running races, our St. Luke's Wheels Off Half-Marathon and Tunnel 10k. The St.Luke's Wheels Off Half-Marathon offers a beautiful route along Lake Superior navigating the scenic north shore drive. The race also adds a one-of-a-kind twist! Runners take a turn at the northern end point of I-35  while entering Duluth and get the experience of running on the Interstate. The Tunnel 10k racers also get the unique experience of running on I-35, through the tunnels both ways. Join hundreds of other runners for this unique fall set of races.

St. Lukes Wheels Off Half Marathon

13.1 Miles | point-to-point 

Run along the scenic North Shore of Lake Superior, on a 13.1 mi point to point course. Enjoy the same spectacular route as the Garry Bjorklund Half Marathon but take the interstate (I-35) for the last 4 miles of the race. During the St. Luke’s Wheels-Off, Half Marathon runners will go through the I-35 tunnels, completely unique to our event and drop down to the St. Louis Bay to finish alongside the famous William A. Irvin freighter as fans cheer you on.

Join hundreds of other runners and enjoy the beauty of fall on the North Shore of Minnesota

NorthShore Tunnel 10k

6.2 Miles | Circle Route

You won't want to miss the chance to run this one-of-a-kind race. The Tunnel 10k race route takes you through 6 tunnels of I-35 and will keep a spring in your step with live music. While most of the time if you are running or walking on an interstate, you are carrying an empty gas can, not during the Tunnel 10K! Our closed course allows you to run on one of the most unique race routes in Minnesota. After experiencing the rare chance to race on an Interstate, you will continue alongside the St. Louis Bay to the finish line at the famous William A. Irvin, a retired lake freighter. Join us come race day!

Lodging & Transportation Information

NorthShore Lodging 

The NorthShore Inline Marathon loves having out-of-town visitors for our event. Because of that, we have made partnerships with local hotels and motels in the area to get you the best deals and a place to stay. Click lodging to learn more.

(Make sure to book early as it fills up fast!)

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. For more information on this program make sure to contact our transportation partner: https://groometransportation.com/minneapolis-st-paul-airport/duluth/

Safety Protocols

On the recommendation of the USOPC, in partnership with our medical provider, our events will follow local public health guidelines for COVID-19 risk mitigation.

Rollerskiers are asked to stay to the right of the roadway. All slower athletes please stay towards the right, all faster athletes please pass on the left and announce yourself as you pass.

The entire course for all NorthShore Races is completely closed to outside traffic. All event participants must be at 26th Avenue East (entrance to the freeway) by 1:30 pm to be able to complete the event. This is Mile 23. The course MUST be open to traffic at 2 pm.

Please be mindful of road conditions. We strive to maintain the best road conditions possible, thanks to local entities like the Minnesota Department of Transportation, the City of Duluth, Saint Louis County, and Lake County. However, there is always the possibility of cracks, “tar snakes”, bumps, sand and rocks, water bottles, garbage, and other obstructions.

First aid will be available on the course and at the finish line. There are vans and motorcycles on the course with medical personnel. All medical expenses incurred by participants are the responsibility of the participant.
