CNO Financial Indianapolis Monumental Marathon

The CNO Financial Group Indianapolis Monumental Marathon — held each November—is Indiana’s premier fall road race and one of the 20 largest marathons in the U.S. Since its debut in 2008, the race has grown steadily, now drawing thousands of participants across its marathon, half marathon, and 5K distances. Starting and finishing near the Indiana Statehouse, the course is fast, flat, and Boston-qualifier friendly, making it a top target for serious runners aiming for PRs. With cool, race-optimized weather and strong local support, the Monumental Marathon has become a Midwest favorite for fall racing. The race has been recognized by Runner's World as one of the "Best Marathons for First Timers. Beyond Monumental, the nonprofit behind this event, contributes significantly to public education, promoting exercise and a healthy lifestyle among Indianapolis youth.
