Rules of Competition

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

You must be officially registered and have an official race bib to participate in any of the Grandma’s Marathon weekend events. Running under another person’s name is strictly prohibited and will result in your disqualification and jeopardize your participation in future Grandma’s Marathon events.

If you become injured or are no longer able to join us for Grandma’s Marathon weekend, you may transfer your bib to another person. This action comes with a $26.95 transaction fee, which is to be paid by the person receiving the transferred entry. No transfers are allowed after May 1.

To transfer your entry, please use your Race Roster account. Once logged in, select the “Transfer” button on the left side dashboard and follow the prompts. This is the ONLY authorized way to transfer your entry to another person. You are responsible for setting the cost of your bib and arranging payment for the entry with the person you are transferring it to.

All entry fees for Grandma’s Marathon weekend events are non-refundable.

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

Participants are allowed to use headphones and similar devices during Grandma’s Marathon weekend events, but they do so at their own risk.

To enjoy all that our racecourses have to offer and for the safety of all participants, we strongly encourage a headphone-free environment while running in either Grandma’s Marathon, the Garry Bjorklund Half Marathon, or the William A. Irvin 5K.

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.

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

IMPORTANT: Emergency vehicles have the right-of-way at all times during the race. The police and traffic control volunteers have everyone’s 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.

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.



Grandma’s Marathon supports USA Track and Field (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 druring Grandma’s Marathon weekend and other prize money events hosted by our organization.


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.


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.


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).
