Grandma’s Marathon

Run Superior. Run the North Shore. 

Since our initial race in 1977, Grandma’s Marathon has grown bigger than just a 26.2 mile race along the scenic North Shore of Minnesota.

It’s a moment where runners of all calibers come together to celebrate the vigor of the human spirit. Where the word “impossible” ceases to exist; a day where 9,000 people are your best running buddy. Tie up your laces for the 44th year of memories, miles and human might.

2021 Grandma’s Marathon Race Weekend Plans

Our plan is to open registration for the 45th Grandma’s Marathon, 31st Garry Bjorklund Half Marathon, and 27th William A. Irvin 5K at half capacity on October 1. Registration will open at 7:00 p.m. central time.

Half capacity will limit the races to 4,000 in-person runners in the marathon and half marathon, and 1,500 in-person runners in the 5K. If the uncertainty around COVID-19 were to subside early enough in 2021, whether via a vaccine or other immunity actions and measures, registration could possibly be reopened to offer more in-person participants the chance to run.

However, if COVID-19 conditions don’t improve, there’s a chance 2021 marathon weekend races will have to be run virtually for the second year in a row. New for 2021, in the case of in-person race cancellation, Grandma’s Marathon will give the registration value back to registrants with a forty percent discount that can be used up to three times over the next five years.

A virtual option will be available from the start of registration as well, however Virtual registrants do not qualify for the cancellation discount plan.



Safety Measures & Procedures:

Grandma’s Marathon was one of the first event organizations in the country to formulate a COVID-19 Preparedness Plan to get people running races in person, as safely as possible during the pandemic. The organization is now planning to couple that experience with guidance from local and state health officials to design the 45th anniversary of Grandma’s Marathon.

“To make runners as comfortable as we could under these circumstances, we started very, very cautiously with the Park Point 5-Miler in early July. It was close to ridiculous how socially-distanced it was, but it felt secure and we received great feedback from the runners in that regard,” states Shane Bauer, executive director at Grandma’s Marathon.

Similar plans will be put into place at the Minnesota Mile and Fitger’s 5K coming up on September 11 and 12, followed by the North End Nightmare event in Superior on October 24.

In preparation for the 2021 Grandma’s Marathon Race Weekend, our staff will be analyzing every facet of the weekend to determine risk and safety measures, considering everything from crowd science to sanitization protocols. At the same time, we will be watching this virus as close as anyone with a direct line to their Medical Director and local infectious disease experts at Essentia Health, a major sponsor of Grandma’s Marathon.

More in-depth COVID-19 Safety Preparedness Plans for the 2021 Grandma’s Marathon Race Weekend will be posted here in the future.

Course information

Grandma’s Marathon is a point-to-point course run on scenic Highway 61 along the beautiful north shore of Lake Superior. The race begins just outside of Two Harbors, Minnesota, and finishes in Duluth’s Canal Park. Grandma’s Marathon is ideal for first time participants as the terrain is relatively flat with some gently rolling hills and a larger incline just before mile 22.

The course is USATF certified. Yellow balloons mark each mile and times are recorded for seven hours (until 2:45 p.m.).
