DULUTH — The race before the race begins Saturday, Oct. 1 for the thousands of runners around the nation who are ready to take on Grandma's Marathon.

Registration opens Saturday for the slate of events, to take place on June 15-17, culminating in what will be the 47th annual marathon from Two Harbors to Canal Park in Duluth.

The 2022 edition had more than 20,000 participants, becoming the event's first full sellout since 2016. Runners were greeted by ideal conditions, which yielded perhaps the event's highest number of personal bests, according to a release from the organization.

Registration for the marathon, the Garry Bjorklund Half Marathon, the William A. Irvin 5K and related events will open on a first-come, first-served basis at 7 p.m. CDT at

All events will be offered on a tiered pricing system, with a base of $40 for the 5K, $110 for the half marathon and $120 for the marathon, with prices going up incrementally on Oct. 16, Jan. 1 and April 1.


The Great Grandma's Challenge allows runners to combine registrations for the 5K on Friday night, June 16 and either the half or full marathon the following day.

Our newsroom occasionally reports stories under a byline of "staff." Often, the "staff" byline is used when rewriting basic news briefs that originate from official sources, such as a city press release about a road closure, and which require little or no reporting. At times, this byline is used when a news story includes numerous authors or when the story is formed by aggregating previously reported news from various sources. If outside sources are used, it is noted within the story.
