BUILT BY COMMUNITY
Since its inception in 1977, Grandma’s Marathon has relied on the community. It is because of the support we’ve received year after year from businesses and individuals in the Duluth area that our race has grown to become one of the largest in the United States.
Grandma’s Marathon weekend brings with it a nearly $40 million economic boost to our region, and runners return to our race year after year because of the experience and hospitality they receive from our community.
We couldn’t do it without you, and we wouldn’t want to! The passion our community has for Grandma’s Marathon is what gives our race its small town charm, and the contributions you’ve made over the years are what allow us to keep improving the world class experience for our participants, volunteers, and spectators.
