About the Undy RunWalk

The National Undy RunWalk series 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.

Most Undy RunWalk events are a 5K, approximately 3.1 miles, and include a one mile fun run, which is untimed. People of all fitness levels attend and all events are timed unless otherwise noted. There are medals for the top three finishers in each age group and all participants receive a pair of our infamous undies to run or walk in.

General Questions

  • What is the Undy RunWalk?

    The Undy RunWalk is a family-friendly underwear-themed run/walk created by the Colorectal Cancer Alliance. The event sparks vital conversations about colorectal cancer – the second leading cause of cancer death in the US – and raises funds and awareness to end this disease within our lifetime.

  • Do you really mean underwear?

    At the Undy RunWalk, we’re drawing attention to colon cancer in a fun and exciting way. But if undies aren’t your thing, no sweat. Some participants sport their favorite pair of family-friendly undies, while others dress as Santa Claus, a superhero or simply as a runner. Whatever your style, you’re sparking lifesaving conversations and helping make colorectal cancer something people are comfortable talking about.

  • What is the distance of the Undy RunWalk?

    Most Undy RunWalk events are a 5K, so approximately 3.1 miles. There is also a one mile fun run, which is untimed. People of all fitness levels attend the Undy RunWalk; if you’re not up for a run, you can always jog or walk!

  • Is the Undy RunWalk a timed event?

    Yes. The 5K is timed (unless otherwise noted) and there are medals for the top three finishers in each age group.

Event Day

  • Can I participate with a stroller? Can I bring my dog?

    Absolutely! This event is for all ages. You are never too young to start spreading awareness about colorectal cancer. Also, four legged friends are our allies too. Well-behaved, friendly, leashed dogs are welcome to participate in the Undy. Bonus if they’re wearing undies!

  • What happens if it rains on event day?

    We hold all events – rain, snow or shine! An event will only be canceled in extreme circumstances. If canceled, there will be no refunds and your registration fee will be considered a tax-deductible donation.

  • What happens if the Undy RunWalk falls on a holiday?

    Our number one goal is to honor colorectal cancer survivors and remember those we have lost while helping bring awareness to a disease that affects people of all races and religions. The Colorectal Cancer Alliance apologizes in advance if an Undy RunWalk event takes place during a holiday. We do our best to avoid holidays, but cities have limited options of when and where an event can be held. Today, the Undy RunWalk is held in many cities throughout the nation and we have to balance the needs of a particular city, as well as manage our national schedule. We thank you in advance for your support and appreciate your understanding.
