The Experience
The Sioux Falls Marathon, powered by Sanford Health and the Sioux Falls Sports Authority, features races for all levels of runners. Distances include the full marathon, half marathon, & 5K. The full & half races feature downtown Sioux Falls, iconic Falls Park (for full and half) and many of the city's finest parks as well as the bike trail system. A portion of the net proceeds from the Sioux Falls Marathon is donated to the Sanford Children's Miracle Network. The 2024 races raised more than $20,000 for children in our community.
