CNO Financial Group Indianapolis Monumental Marathon 2026

The CNO Financial Group Indianapolis Monumental Marathon begins and ends in downtown Indianapolis, offering marathon, half marathon, and 5K races each autumn. The marathon is one of the 15 largest in the U.S. The logistics are straightforward for participants: hotels are located near the start and finish areas, and the airport is approximately 15 minutes from the city center. The USATF-certified courses are known for being fast and flat, attracting a diverse field of runners including first-time marathoners, half marathoners, those seeking personal bests, Boston Marathon hopefuls, and elite competitors. The course winds through downtown, historic areas, and past Indianapolis's monuments. Charity groups, such as Active Minds, utilize the event weekend to gather support for mental health advocacy focused on youth and young adults.
