Grandma's Marathon celebrates its 50th edition on Saturday 20 June, and the milestone has drawn one of the strongest women's fields the Duluth classic has assembled. The point-to-point course runs from Two Harbors down the North Shore of Lake Superior into Duluth, Minnesota, with the elite and semi-elite fields due to set off at around 7:40am as one of American distance running's most cherished summer fixtures reaches its half-century.
The headline storyline is the return of Dakotah Popehn, a two-time winner who triumphed in back-to-back years in 2021 and 2022 and is racing the full marathon for the first time since 2023. Her 2022 winning time of 2:25:01 still ranks as the third-fastest a woman has run on the course, and she arrives in form, having clocked a personal best of 2:24:02 at the 2026 Boston Marathon, where she finished 12th. Victory would make her only the third woman to win Grandma's three times.
Standing in her way is defending champion Lilian Chebii, the 32-year-old who set a personal best of 2:25:14 to win last summer. That mark sits fourth on the all-time Grandma's list, just 13 seconds adrift of Popehn's 2022 time, setting up a contest between two of the fastest women in the race's history. With several other established marathoners and rising domestic talents in the mix, the women's race looks the most competitive part of an already deep weekend programme.
The course itself remains a draw for those chasing fast times. Grandma's is prized for its scenic, largely flat profile along the lakeshore, with a gentle net descent of roughly 130 feet from start to finish that has long made it a destination for marathoners hunting personal bests and Olympic Trials-calibre performances. Cool early-summer mornings on the North Shore frequently provide favourable racing conditions, although lake-driven weather can shift quickly.
Beyond the elite race, the anniversary edition carries broader significance for a community event that has grown from modest beginnings into one of the largest marathons in the American Midwest, drawing tens of thousands of runners and spectators to the region each June. As the 50th running approaches, the combination of a landmark occasion and a marquee head-to-head at the front of the women's field has Duluth braced for one of its most memorable weekends yet.
