Welcome to the Undy Run/Walk!

The Undy Run/Walk is a family-friendly event created by the Colon Cancer Alliance. It is unique because participants are encouraged to dress up and get talking about colon cancer! When people get talking, we know we’re saving lives and honoring our loved ones.

The Undy Run/Walk is the Colon Cancer Alliance’s signature fundraising event and helps us fund our mission to knock colon cancer out of the top 3 cancer killers. Funds raised through the Undy Run/Walk support both local and national colon cancer prevention and patient support programs. In fact, in 2014 $0.86 of every dollar received went directly to helping patients and their families in need.

Support our mission. Register for an Undy Run/Walk!


Of course the Undy Run/Walk is about having fun and knocking out colon cancer. We also know that many of you want the specifics about the course and timing of the race. So never fear, most Undy Run/Walk 5K courses are USATF certified and unless otherwise noted, the 5K will be timed.
