Grandma’s Marathon

Run Superior. Run the North Shore. 

Motivation, inspiration and perspiration.

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 42nd year of memories, miles and human might.

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.).
