Empowering Blood Donors
Promoting voluntary blood donation to keep supplies safe and available.
Attention marathon participants and supporters! Join us in the heart of Chennai for a premier running event dedicated to raising crucial awareness about Blood Donation and Organ Donation. Every step you take fuels a life-saving mission.
Every day, countless lives hang in the balance, waiting for a compatible blood type or a life-saving organ. The OMR MARATHON is committed to bridging this gap by focusing on awareness, education, and direct action.
Promoting voluntary blood donation to keep supplies safe and available.
Your registration fee supports awareness campaigns, educational programs, and partnerships with local blood banks — converting awareness into real action.
Blood donation is one of the most meaningful contributions a person can make to society. It is a simple act with the power to save multiple lives. Hospitals rely on donated blood every day to support accident victims, surgical patients, and individuals with blood disorders.
One blood donation can help up to three lives, offering hope to those in critical need. Beyond helping others, donors also benefit from basic health screening and the natural renewal of blood cells.
By participating in this marathon, you’re not only showcasing your strength but also extending compassion beyond the race. Together, we create stronger, healthier communities where every donor becomes a hero.
Running in a marathon for blood-donation awareness is a powerful way to inspire others and bring attention to a lifesaving cause. Marathons naturally attract large crowds, media coverage, and community participation—making them an ideal platform to highlight the urgent need for regular blood donation.
A marathon represents endurance, strength, and compassion—the same values that define blood donors. Just as runners push themselves to reach the finish line, blood donors give a part of themselves to help someone fight another day. This symbolic connection makes the message more relatable and impactful.
When people run for this cause, they increase visibility, start important conversations, and motivate individuals who may have never considered donating blood before. This helps break myths, reduce fear, and encourage more voluntary donors.
Ultimately, participating in a marathon for blood-donation awareness transforms athletic effort into community impact—turning movement into meaning and participation into the power to save lives.
The OMR MARATHON was founded in 2025 by passionate runners, medical professionals, and community leaders who recognized the urgent need for a dedicated movement supporting life-saving blood and organ donations.
We believe awareness is the first step toward action. Our mission is to educate, inspire, and mobilize the community by creating a marathon that stands for hope, generosity, and life-saving impact.
A compassionate community where donation becomes a natural act of kindness and every individual contributes to saving lives.
We need passionate individuals to help with hydration, route guidance, and managing donation booths.
