Rules of Competition

Rules of the routes.

Confirmation of entry

Entries will be confirmed via email immediately after registering. Official confirmation will be emailed to all registrants prior to the race.


Transferring race numbers

If you become injured or are no longer able to join us for Grandma’s Marathon weekend you may transfer your entry to another person for $26.95 + transaction fee. To do so, visit the “Manage My Entry” and follow the instructions. No transfers will be accepted after April 1, 2017.

IMPORTANT:  This is the ONLY authorized way to transfer your entry to another person.

Running under another person’s name is strictly prohibited and will result in disqualification and jeopardize your participation in future Grandma’s Marathon events. Entry fees are non-refundable. If you choose to transfer your entry to another person, you are responsible for arranging payment for the entry with the person you are transferring it to.


No early starts

Absolutely no early starters are allowed on the racecourse. Individuals in violation of this rule will be disqualified and asked to leave the course. No automobiles, bicycles, baby joggers, roller skis, inline skates, hand cycles, hand-cranked wheelchairs, pets or unofficial participants are allowed on the racecourse.


Headphones allowed for certain races

At its annual meeting in December 2008, USA Track & Field (USATF) amended rule 144.3(f) effectively lifting its previously imposed ban on headphones and other similar devices on USATF-certified courses. Because of this change, participants will be able to use headphones and similar devices during Grandma’s Marathon, the Garry Bjorklund Half Marathon and William A. Irvin 5K, but they do so at their own risk.

To enjoy all that our racecourses have to offer and for the safety of all participants, Grandma’s Marathon-Duluth, Inc. strongly encourages a headphone-free environment during the running of Grandma’s Marathon, the Garry Bjorklund Half Marathon and the William A. Irvin 5K.


Zero tolerance drug policy

Section 1: Opening Statement

Grandma’s Marathon supports the USATF Zero Tolerance Action Plan to catch cheating athletes and coaches that are using or supplying performance-enhancing drugs. Grandma’s Marathon will work closely with and will encourage the USATF to perform drug testing annually at Grandma’s Marathon and other prize money events hosted by Grandma’s Marathon-Duluth, Inc. Furthermore, we are committed to assisting the USATF with their efforts to educate coaches and athletes that drug use is morally and ethically wrong, dangerous to one’s health, and detrimental to the sport of running.

Section 2: Recruitment Policy

Grandma’s Marathon will immediately disqualify any athlete that has tested positive for using performance enhancing drug(s) at any race hosted by Grandma’s Marathon, and will no longer recruit that athlete for future races. Prize money and incentive bonuses will not be awarded to athletes that have tested positive for performance enhancing drugs at Grandma’s Marathon races.

Furthermore, when an athlete returns to competition after serving a USATF and/or IAAF suspension for using performance enhancing drugs at Grandma’s Marathon or another race, Grandma’s Marathon will no longer actively recruit that athlete and will not provide food, lodging and/or travel assistance to any future Grandma’s Marathon events.

In addition, Grandma’s Marathon will terminate any agreement that has been made between the race and an athlete regarding complimentary entries, food, lodging and/or travel assistance should the athlete be found guilty of using performance enhancing drugs after the agreement was made. Grandma’s Marathon will also terminate said agreement(s) should race organizers gain knowledge of an athlete’s prior drug use suspension after the agreement was made.

As a result of any of the above scenarios, Grandma’s Marathon will immediately cease all business relationships with the athlete’s coach and/or agent.

Section 3: Athlete Affidavit

Prior to competing, it will be mandatory for each elite athlete in Grandma’s Marathon and the Garry Bjorklund Half Marathon to sign an affidavit stating that he/she is not using any performance enhancing drugs, and that he/she is familiar with the Grandma’s Marathon Drug Use and Recruitment Policies (sections 1 and 2 above).

Racecourse courtesy

Please be considerate of your surroundings during Grandma’s Marathon. Use the portable toilets provided at the start and along the course at the aid stations, rather than private yards or gardens.

Remember: emergency vehicles have the right-of-way at all times during the race. The police and traffic control volunteers have YOUR safety in mind, and deserve to be treated respectfully by runners and spectators alike.

Runners who have finished the race need to avoid interference with runners approaching the finish line.

The atmosphere along the Grandma’s Marathon courses is second to none. We believe your race experience will be greatly enhanced by having complete use of all of your senses. Running headphone-free allows opportunities to develop camaraderie with your fellow runners and to enjoy the various entertainment acts lining the course. Plus, thousands of enthusiastic volunteers and spectators will be cheering you on, helping to get you to the finish line.

Runner safety has always been, and will continue to be, a priority for all of our events. Please be mindful of the other participants and race personnel to ensure a safe and enjoyable race for everyone.


Youth Races

No motor vehicles, bicycles, baby joggers, strollers, hand cycles, hand-cranked wheelchairs, roller skis, inline skates, pets or unofficial participants are allowed on the racecourse. Wheeler athletes must race under their own individual power.

The 2-Mile race-walk is a non-monitored recreational walk. Awards are given on an honor system. If you are registered for the 2-Mile walk, you must walk the entire distance—no running is allowed. For the safety of all participants, the use of headphones or other similar devices is not allowed during the Park Point 5-Miler, 2-Mile Walk and/or Youth Races.
