Monumental Marathon

Monumental Marathon: Run For A Cause

The CNO Financial Group Indianapolis Monumental Marathon takes place every November. This marathon is among the 15 largest marathons in the United States. The Indianapolis Monumental Marathon is the ideal fall marathon for everyone from the first-time marathon runner to elite athletes. Nationally recognized as flat and fast, this event has hosted Olympians, PR seeks, and thousands of Boston Marathon qualifiers.

When you participate in the CNO Financial Indianapolis Monumental Marathon as a member of Overdose Lifeline team, your efforts and donations raised will support the programs and work of Overdose Lifeline—helping communities, families and individuals affected by the chronic disease of addiction. 

Update: CNO IMM has gone virtual in 2020!

Due to the COVID-19 pandemic and concerns about participant safety, this year’s CNO Financial Indianapolis Monumental Marathon (CNO IMM) will be held as a virtual event. If you have already registered, you should have received an email from Beyond Monumental with information on updating your registration to participate virtually, donate your registration, defer to 2021, or request a refund. Overdose Lifeline hopes you choose to participate virtually and join our team! If you choose to participate in the virtual CNO Indianapolis Monumental Marathon event, the competition window to complete the distance is November 1–30!

The U.S. is in the midst of an opioid overdose epidemic with every American state, county, socio-economic and ethnic group impacted. Overdose Lifeline, Inc. (ODL) is dedicated to helping individuals, families, and communities affected by the disease of addiction / substance use disorder through advocacy, education, harm reduction, prevention, resources, and support. COVID-19 has affected each and every one of us. While the world is in the midst of a pandemic, the U.S. opioid overdose epidemic has not stopped. Being in isolation, away from family and friends, with regular routine interrupted, the number of overdoses has grown significantly. Since last April, we have seen more than a 90% increase in overdoses. Your support enables us to keep providing helpful resources, harm reduction services, and opioid education in our community.
