Grandma's Marathon reaches a landmark this weekend as the Duluth classic celebrates its 50th edition, with race day set for Saturday 20 June and more than 19,000 participants expected across the weekend's events. The point-to-point course remains one of the most scenic and fastest in North America, running along Scenic Highway 61 from near Two Harbors and hugging Lake Superior's North Shore for some 20 miles before finishing in historic Canal Park beside the Aerial Lift Bridge, where tens of thousands of spectators gather.
The anniversary has been marked by record demand. The 50th edition sold out in record time, and organisers have built a full festival around the milestone, including a new drone show among the headline attractions of an expanded weekend lineup. The Garry Bjorklund Half Marathon, now in its 36th year, runs alongside the marathon on Saturday morning, and the combined fields give the small Minnesota port city the feel of a national running capital for a few days each June.
Much of the home attention falls on Dakotah Popehn, the St. Francis, Minnesota native and 2024 US Olympian who won back-to-back Grandma's titles in 2021 and 2022. Her 2:25:01 from 2022 still ranks as the third-fastest time any woman has run on the course, and this weekend she returns to chase a place in history as just the third woman to win the race three times. A strong supporting cast across the elite and semi-elite fields means she will have to earn it on a course that rewards even pacing and respect for the early downhill miles.
Race-day logistics reflect the scale of the event. The start sequence begins at 7:35 a.m. for wheelchair and adaptive athletes, with the elite and semi-elite fields rolling out from around 7:40 to 7:45 a.m. and the citizen corrals following through 8:10 a.m. Local authorities have published detours and traffic guidance for the North Shore, a reminder that an event of this size reshapes the region for the weekend as runners, families and spectators converge on Duluth.
Beyond the elite storylines, Grandma's at 50 is a celebration of the everyday runner. The field spans first-time marathoners, Boston qualifiers chasing the famously honest course, and stories of perseverance that capture why the race endures, including participants returning from serious injury to reach the start line. For all the records and prize money on offer, it is that breadth of participation, set against the backdrop of the big lake, that has carried Grandma's through half a century and shows no sign of slowing.
