Sioux Falls Marathon

Lace up for the Sioux Falls Marathon on September 20, 2026, a celebrated event in Sioux Falls, South Dakota, offering full marathon (26.2M), half marathon (13.1M), and 5K distances. This USATF-certified course is a Boston Qualifier, taking runners on a scenic journey through the heart of the city and its natural beauty. You'll traverse downtown Sioux Falls, charming neighborhoods, and utilize the city's extensive bike trail system.

The marathon course is primarily a loop, featuring a mixed terrain that includes some early rolling hills with an overall elevation gain of approximately 300 feet, leading into a predominantly flat final 10 miles. Runners consistently praise the picturesque segments, especially around mile five, as the route winds past the iconic Falls Park, which gives the city its name. Expect top-notch support with regular aid stations providing water, electrolytes, and sometimes gels or other food, ensuring you stay fueled throughout your race. The race culminates with an exciting finish on the track at Howard Wood Field. Beyond the personal challenge, participating in the Sioux Falls Marathon also contributes to a good cause, as a portion of the net proceeds benefits the Sanford Children's Miracle Network Hospital.

With typical race day conditions seeing highs around 75°F and lows around 51°F, and only an 11% chance of precipitation, the weather often provides a favorable backdrop for a strong performance. Many runners appreciate the well-organized nature of the event, the enthusiastic volunteers, and the strong sense of community support that helps propel participants across the finish line. The Sioux Falls Marathon offers a delightful blend of challenge and reward, making it an unforgettable experience whether you're chasing a personal record or simply enjoying the scenic route.
