CNO Financial Indianapolis Monumental Marathon

The CNO Financial Indianapolis Monumental Marathon, first held in 2008 and grown steadily into one of the Midwest's premier fall marathons, celebrates Indianapolis's civic landmarks and community spirit. Over nearly two decades the race has become a signature event for the city, attracting competitive road racers aiming for personal bests and Boston qualifying times as well as recreational runners and relay teams. Organized by local race professionals with strong volunteer support, the event emphasizes accessibility, race-day logistics, and charitable partnerships that reflect its roots in the Indianapolis running community.

The course is a fast, largely flat tour of downtown Indianapolis and neighboring neighborhoods, showcasing Monument Circle and the Soldiers and Sailors Monument, the scenic White River and Canal Walk, and tree-lined residential sectors that add variety and shade. Runners experience broad, well-paved streets, typically calm autumn weather, and lively spectator support with bands, cheer zones, and neighborhood aid stations that create a festival-like atmosphere. The race is USATF-certified and a recognized Boston Qualifier, with course measurement standards consistent with national and international timing practices; it also participates in AIMS-level certification protocols. Whether targeting a qualifier, a new PR, or a first marathon finish, participants consistently report a well-organized event with enthusiastic crowds, clear course markings, and excellent race-day amenities.
