The Undy 5000 was created by the Colon Cancer Alliance (CCA) in 2008. It’s a family-friendly 5K run/walk that is unique because participants are encouraged to run in their underwear to bring attention to the area affected by colon cancer. It is the second-leading cause of cancer deaths in the nation, and yet it is one of the most preventable cancers! We have found that by getting people talking about this disease, we can save lives!

At its inception in 2008, the Undy 5000 started out in just 3 cities – Philadelphia, Dallas and Phoenix. Since then, it has made its way to 14 cities nationwide, and continues to grow every year!
