CNO Financial Group Indianapolis Monumental Marathon

The CNO Financial Group Indianapolis Monumental Marathon takes place in downtown Indianapolis during the fall. It includes a marathon, half marathon, and 5K, all beginning and ending in the city center. The marathon is one of the 15 largest in the United States. The race is easily accessible for visitors, with downtown hotels located within the Mile Square and the airport approximately 15 minutes away. The courses are USATF-certified, fast, and flat, making the event a suitable choice for those running their first marathon or half marathon, and for athletes aiming for personal bests. The course travels through central Indianapolis, featuring well-known monuments and historic areas rather than routes far from the city. Spectators can support runners from downtown locations along the course, contributing to a lively atmosphere that retains a local character. Since 2008, the event has attracted Olympians, elite athletes, thousands of Boston Marathon qualifiers, club runners, first-time participants, and many individuals seeking to improve their race times.
