2016 St. Louis Undy Run/Walk
The Undy Run/Walk isn’t your everyday run. A fun twist on a serious topic, the Undy Run/Walk is sparking much-needed conversations and kicking colon cancer butt, one city at a time. As we head into our 8th year, we’re proud to share that we’ve raised more than 9 million through this underwear-themed event. We’re super proud, but we also know our work isn’t done. That’s why we continue hitting the streets in our briefs and asking you to join us.
