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

It’s now become a can’t miss weekend in June, a moment when participants of all calibers come together to celebrate the vigor of the human spirit.

It’s a day the word “impossible” ceases to exist, a day 9,000 people become your best running buddy.

Tie up your laces for the 45th year of memories, miles, and human might.


2021 Cancellation Plan

If COVID-19 conditions do not improve, there’s a chance we will have to cancel the in-person version of Grandma’s Marathon weekend for the second year in a row.

If that happens, all participants registered for an in-person race will be automatically switched to the virtual option and receive new instructions for completing their race.

Those registrants will also receive a 40% discount that can be used (3) times over the next (5) years on any Grandma’s Marathon weekend race.

NOTE: Participants registered for a 2021 virtual race DO NOT qualify for the cancellation discount plan.
