Grandma's Marathon is an annual road race held each June in Duluth, Minnesota, in the United States. The course runs point-to-point from the town of Two Harbors on Scenic Route 61 and continues along Lake Superior into the city of Duluth. The finish is located in Canal Park, near Grandma's Restaurant, which is next to the highly visible Aerial Lift Bridge.
Grandma's was first run in 1977 with only 150 participants; the first race was won by Minnesotan and 1976 Olympic 10000m runner Garry Bjorklund. The newly opened Grandma's Restaurant was the only local business that would sponsor the then-fledgling event, for the fee of $600. Race organizers then named the new race after the restaurant. Grandma's Marathon is now run by almost 10,000 runners every year, has nearly a $2 million operating budget and is credited with bringing tens of millions of tourist dollars into the city of Duluth.
The men's record time for Grandma's is 2:09:06, set in 2014 by Dominic Ondoro of Kenya. The previous record of 2:09:37, set in 1981 by Wayzata, Minnesota native Dick Beardsley stood for 33 years before being broken. The women's record time is 2:26:31, set in 2013 by Sarah Kiptoo. In 2005, Halina Karnatsevich was the first finisher with a time of 2:33:39 but she was later disqualified for failing her post-race doping test.
Grandma's includes several other running events in addition to the full marathon. These include the Garry Bjorklund Half Marathon, the William A. Irvin 5k, the Fitger's 5k, the Park Point 5 Miler, and the Grandma's Minnesota Mile, as well as several "whipper snapper" races for kids.
