Safety Protocals

Helmets are mandatory at all times while on the racecourse for skating and rollerski races. Wrist, knee, and elbow protection are also recommended.

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 opened 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.
