Brookings Marathon

First held in 1970, the Brookings Marathon in Brookings, South Dakota, is the 25th-oldest marathon in the United States and the third-oldest to have been run every year without interruption since it began. The program includes a 5K on October 1, 2027, followed on October 2, 2027, by the marathon (26.2 miles / 42.2 km), the marathon relay and the half marathon (13.1 miles / 21.1 km).

This traditional South Dakota race takes runners through historic neighborhoods, scenic parks, bike paths and tree-lined streets, blending local heritage with natural surroundings. Known for its small-town charm and strong community spirit, it brings out hundreds of volunteers and many families who cheer on participants along the entire course. Over the decades the event has evolved to meet the expectations of today's runners while keeping the warm atmosphere that has defined it for more than fifty years.
