The National Undy RunWalk is not just an opportunity to run or walk in your underwear. It is a family-friendly undy-themed RunWalk created by the Colorectal Cancer Alliance, with the goal to provide support for patients and families, caregivers, and survivors; to raise awareness of preventive measures; and inspire efforts to fund critical research. All fitness levels attend. Dogs are welcomed! All participants receive a pair of Undy RunWalk boxer shorts, light food and beverage and for our 5K participants, timing services.
