More Info


Rummage up the Ugliest Sweater you can find and celebrate the Holidays by participating in the Merriest 5K of the year. Join thousands of runners, walkers and prancers from around the nation as The Ugly Sweater Run tours North America. If you’ve never participated in a 5K, this is a perfect way to burn some calories, have some fun and immediately replace those calories with a warm hot chocolate, and a Kahlúa cocktail. All you have to do is register!

The run is approximately 3.1 miles, through city streets and scenic parks. The start line includes massive inflatables, photo stations, games and the most cheerful holiday music.  Join us at the finish line and take a family photo in a larger than life snow-globe, run through our fake snow and so much more!

Once you’ve completed the merriest run of your life, join us for some post-event festivities. We have everything your five-year old self could want with a few perks of adulthood. Take a much-deserved break from the shopping frenzy, and celebrate your sweater filled day with a Kahlúa cocktail, and other holiday goodies. Awards for Best Ugly Sweater, Best Kids Sweater, Best Pet Attire and Best Real/Fake Mustache/Beard will be declared. Register now and join us for a truly unforgettable tradition!

The Ugly Elves are the backbone of this event. Our Volunteers help with checking in participants, passing out swag, handing out beverages, spreading holiday cheer, and seriously putting the “elf” in selfie.

All volunteers will receive the following:

  • A comfy beanie
  • A free run (if you volunteer at packet pick-up the day prior to the event)
  • Free Hot Chocolate
  • Kahlúa wants to hook you up with a complimentary post-race cocktail (21+ only). Please enjoy responsibly.
  • Community service hours
  • The Merriest 5K of your life

You can even log some community service hours! Come on, it’s the holiday season! Time to be the upstanding citizen you always wanted to be.

We are looking for as many helpful elves as possible so tell your friends, family, and estranged co-workers. Please contact Volunteer Manager, Carol Hiller at [email protected] or 303-668-2322 if you have any questions or click the link below to sign up.
