No, our organization does not keep a wait list.
REFUNDS, DEFERMENTS, & CANCELLATIONS
Entry fees are non-refundable. The only exception to this is for those who are on active military duty and deployed for service during race weekend (a copy of deployment orders is required).
Entry deferments are not permitted under any circumstances.
It is the primary goal of Grandma’s Marathon to ensure a safe event for all involved. We will not expose participants or the community to undue risk because of staging our event. There may be times when we feel it is unsafe to continue with the race(s). While we recognize the aspirations and commitment of those that have entered the race(s), we will make decisions about the race(s) based on the population as a whole. Furthermore, if the community resources are threatened, we will act to protect them from unnecessary stress.
Specifically, when pandemics, weather, or other physical conditions present a danger to participants as a whole, we maintain the right to cancel the race(s). Less threatening conditions could result in an alteration of the course or race length to promote a safer result for the participants. These conditions will be recognized as “an act of God” and will not result in the refunding of race entry fees or future race credits. The staging of a race of this magnitude results in substantial expense prior to the actual race itself. Thus, in the event of a forced cancellation of the event, it is very likely that the financial impact on the race would not be any different than if the race was held without compromise.
The Executive Director, with input from staff, the Medical Director, Board of Directors, and other community partners, will make the final decision regarding the cancellation or alteration of the race(s). Prior to the race(s), race staff will apprise participants of forecasted weather conditions and any course modifications. In the event of a course evacuation, marathon personnel or law enforcement will direct runners to designated shelter areas.
Severe thunderstorms with the threat of lightning that are forecasted to continue throughout the day of the event may result in cancellation of the event for all participants.
In case of severe heat and humidity, the Executive Director will have the authority to either cancel or shorten any of the day’s race(s).
In the event a cancellation or alteration takes place, Grandma’s Marathon will advise participants through various traditional and non-traditional media channels on a timely basis.
LODGING & TRANSPORTATION
A list of area hotels and other lodging options is available HERE. Many hotels do not accept online bookings for Grandma’s Marathon weekend, so we suggest calling the hotel to check availability and secure your room.

RACE PACKET PICKUP
Packet pickup will be available on Thursday and Friday of race weekend.
An email with your bib number will be sent the week of the race. Please bring that email – either a printed copy or a digital version on your mobile phone – to pick up your packet on race weekend.
IMPORTANT: There is ABSOLUTELY no race packet pickup on race morning, and all participants must show a photo ID to pick up their race packet. Your ID will be used only to match your first and last name to your registration.
Yes, someone else can pick up your race packet.
To do this, please complete the authorization form (found at the bottom of your bib number email you will receive on race week) and have the selected person bring the printed, authorized confirmation to race packet pickup.
For a $25.00 fee (within the United States only), you can have your race packet shipped to you 10-14 days before race day.
This service is available to Grandma’s Marathon and Garry Bjorklund Half Marathon participants only. It is not available to William A. Irvin 5K or Great Grandma’s Challenge participants.
IMPORTANT: The last day to request to have your packet mailed to you is May 20. Requests received after this date will not be accepted. NO EXCEPTIONS.

Running with the community can make things easier during those long months of training, so we want to connect as many of our participants as possible.
We’ve created an online, public Facebook group called Grandma’s Marathon Weekend Participants. There, our participants can connect with each other to motivate, support, and celebrate each other in the months leading up to race day.
We welcome all athletes to be part of our race weekend, and we will make every effort to honor every reasonable request for accommodation. Please call our office at (218) 727-0947 or email us at [email protected] and we can discuss your needs.
Yes, participants are able to request lactation or approved medical device support for Grandma’s Marathon or the Garry Bjorklund Half Marathon.

IMPORTANT: Grandma’s Marathon is unable to safely transport or store breast milk at this time. We understand the sensitivity of this issue and apologize for the inconvenience.

SPECTATOR INFORMATION
While our racecourse provides plenty of natural beauty along the north shore of Lake Superior, the areas for spectators are limited in the early miles of both Grandma’s Marathon and the Garry Bjorklund Half Marathon.
It’s recommended that spectators choose a location within the Duluth city limits to watch on race day. Some of the most popular and accessible viewing locations are detailed HERE.
One of the best ways on race day to keep track of your favorite runners is by using the live tracking feature on our Grandma’s Marathon mobile app, powered by ASICS.
Available on Apple and Android devices, the live tracking will show you exactly where your family and friends are on the course so you can be sure not to miss them as the pass by.
NOTE: The Grandma’s Marathon mobile app is available for download at any time, but the live tracking feature will not be accessible until race morning. Because of limited cell coverage in some remote areas of the racecourse, there may be some delays in tracking during portions of the race.
