Undy Run/Walk

March 03, 2018 · San Diego, CA

Distance: 1K Fun Run, 5K

The Undy Run/Walk is a family-friendly event that was created by the Colon Cancer Alliance. It is unique because participants are encouraged to run in their boxers to bring attention to the area affected by colon cancer. We have found that by getting people talking about this disease, we can save lives!


  • A pair of 2018 Boxer shorts
  • Survivor t-shirt if registered as a survivor
  • Survivor medal if registered as a survivor
  • Access to our online fundraising platform
