Grab the kids and grab the dog, but leave your pants at home! Run in your underwear while raising awareness of colon cancer. Instead of race day T-shirts, all registered participants receive a commemorative pair of Undy 5000 boxers. It is a family-friendly event open to all ages. In addition to a 5k race, there is also a one-mile fun run. A giant, walk-through inflatable colon will also make an appearance at the event!
