Mill Race Marathon

The Mill Race Marathon is an annual race event held in downtown Columbus, Indiana, set for September 26–27, 2025. It offers a full marathon, half marathon, and 5K, along with a free Kids Fun Run for children through 6th grade. The event includes food, music, and family-friendly activities post-race, creating a festive atmosphere for participants and spectators alike.

Columbus, known for its rich industrial history, hosts this well-organized race focused on promoting healthy lifestyles. The course is mostly flat and fast, running through neighborhoods and along a paved greenway rather than the city’s famed architecture and public art, which some runners find a missed opportunity. The marathon experience features great volunteer support, good course signage, and a lively finish line party with bands and food. Entry fees apply, with early registration discounts available, and the event is handicapped accessible.

Leading up to race weekend, a 17-week training program runs from late May through the race day, featuring classes and running practices to help participants prepare safely and progressively for their chosen race distance. Training sessions cover running tips, injury prevention, nutrition, and appropriate gear, supported by the Columbus Running Club.
