One of American distance running’s most beloved institutions reaches a landmark this weekend, with Grandma’s Marathon staging its 50th edition on Saturday morning along the North Shore of Lake Superior. What began in 1977 as a small race organised by a handful of Duluth running enthusiasts has grown into one of the largest and most prestigious marathons in the United States, and the half-century mark has drawn a swell of returning champions, first-time entrants and spectators to the Minnesota lakefront.
The race retains the point-to-point character that has defined it for five decades, sending runners south-west from Two Harbors down Scenic Highway 61 toward the finish in central Duluth. The course is fast and largely gentle, shadowing the cold expanse of Lake Superior for much of its length, and the lake’s influence has long made early-morning conditions a decisive factor. A cool, still start can produce quick times; a warm or humid morning can punish even the best-prepared field over the closing miles into the city.
As ever, Saturday’s programme is anchored not only by the marathon but by the Garry Bjorklund Half Marathon, which starts later on the same course and swells the weekend’s total participation to tens of thousands across the two races. The combined entry makes the event one of the busiest running weekends in the American calendar, and the surrounding festival—expo, shake-out runs and a packed finish area—has become a fixture of early summer in the Upper Midwest.
At the front of the women’s race, attention centres on Dakotah Popehn, the United States Olympic marathoner and two-time Grandma’s champion, who returns to Duluth chasing a historic third title in the race’s 50th year. Popehn’s familiarity with the course and her form on the roads make her a natural focal point, though a deep international field stands between her and the milestone victory. The men’s race, as is traditional at Grandma’s, features a strong East African contingent capable of pushing toward the event’s long-standing course records should the weather cooperate.
For all the elite intrigue, the 50th edition is as much a celebration of mass participation as of fast times. Grandma’s has built its reputation on the experience it offers the thousands of club runners, charity entrants and first-time marathoners who travel to Duluth each June, and organisers have framed the anniversary as a tribute to that community as much as to the athletes at the sharp end. The gun fires on Saturday morning; until then, Duluth waits on the weather and the lake.
