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.


Ready to Run Pledge

The Ready to Run Pledge is a social contract that all participants, attendees, volunteers, vendors, and staff will agree to for the 2021 Grandma’s Marathon weekend.

This pledge is an acknowledgment of personal responsibility, communal respect, and commitment to health and safety. Grandma’s Marathon is a community event, and our approach to keeping everyone as safe as possible must also be a community effort.

All 2021 Grandma’s Marathon weekend participants and attendees will pledge to:

  • Follow all current and existing guidelines set forth by the Minnesota Department of Health (MDH) and Centers for Disease Control (CDC)
  • Stay home and away from others if experiencing any symptoms related to COVID-19 prior to the event
  • Respect the space of others by maintaining appropriate social distance, and use caution when around large groups during the entirety of the event
  • Follow all instructions from event staff and volunteers

NOTE: COVID-19 vaccinations will not be required from Grandma’s Marathon participants, volunteers, or attendees, but everyone is strongly encouraged to follow the current MDH and CDC recommendations. Masks or face coverings and appropriate social distancing are strongly encouraged throughout the event, regardless of vaccination status.


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.
