2021 Grandma’s Marathon Race Weekend Plans

Grandma’s Marathon, Garry Bjorklund Half Marathon, and the William A Irvin 5k are full at half capacity for 2021.  Half capacity limits the races to 4,000 in-person runners in the marathon and half marathon, and 1,500 in-person runners in the 5K.

Those still interested in participating can reach out to one of our official charity partners or run virtually.

If COVID-19 conditions don’t improve, there’s a chance 2021 marathon weekend races will have to be run virtually for the second year in a row. New for 2021, in the case of an in-person race cancellation, Grandma’s Marathon will give the registration value back to registrants with a forty percent discount that can be used up to three times over the next five years. Participants who register as a virtual participant do not qualify for the cancellation discount plan.


Safety Measures & Procedures:

In preparation for the 2021 Grandma’s Marathon race weekend, our staff continues to analyze several changing factors to determine the potential risk and appropriate safety measures. We are relying on the analysis of our Medical Director and his team at Essentia Health as well as our state and local health partners, who are closely monitoring the changing situation and conditions.

We are hopeful our success and experiences organizing other small events since summer will help us create a workable modified plan ahead of  Grandma’s Marathon weekend in June. In addition to working with the experts listed above, we have also employed a crowd science analysis of our specific participant flow and density, which will help give us the data necessary to create the safest possible race environment.
