Athletics Registration opens October 1 for 2023 Grandma’s Marathon Weekend

(DULUTH, MINN.) --- Registration will open on Saturday, October 1 for the 2023 Grandma’s Marathon weekend, which hosted more than 20,000 runners this past summer in reaching the organization’s first total sellout since 2016.

Helped by wonderful weather for runners, the 2022 race weekend saw perhaps the event’s highest-ever number of personal records run across the weekend’s three races – Grandma’s Marathon, the Garry Bjorklund Half Marathon, and the William A. Irvin 5K.

“It was certainly quite the return to the Grandma’s Marathon weekend we’re all used to around here,” said Marketing & Public Relations Director Zach Schneider, referencing two years of alterations to race weekend due to the COVID-19 pandemic. “Our participants, volunteers, and community members all deserved a race weekend like that after all they’ve been through, and now we feel as an organization that the bar’s been raised even higher headed into 2023.”

The 2023 Grandma’s Marathon is scheduled for June 15-17, and registration for the weekend’s races will open on a first-come, first-served basis at 7:00 p.m. CT on Saturday, October 1. To register or to find more information, please visit

The 2023 race weekend will also feature several community events and activities that are open to the public, including free live music and entertainment at Bayfront Festival Park on Friday night and all day Saturday as well as the Essentia Health Fitness Expo, Michelina’s All-You-Can-Eat Spaghetti Dinner, and Whipper Snapper Races for Kids.


Grandma’s Marathon began in 1977 when a group of local runners planned a scenic road race from Two Harbors to Duluth, Minnesota. There were just 150 participants that year, but organizers knew they had discovered something special. Grandma’s Marathon weekend draws approximately 20,000 participants for its three-race event each June.

The race got its name from the Duluth-based group of famous Grandma’s Restaurants, the first major sponsor of the Marathon. Over time, the level of sponsorship with the restaurants changed, but the name stayed the same. Grandma’s Marathon-Duluth, Inc. is a 501(c)(3) tax-exempt nonprofit organization with a 17-member Board of Directors and a nine-person, full-time staff.
