From the Organizer
Get into the holiday spirit with the Ugly Sweater 5K! Runners and walkers, young and old, are invited to join us at Washington Park in Denver for a flat, fast 5K. Dress in a tacky sweater – the more tinsel, bows, reindeer and candy canes, the better. It’s not a fashion faux pas if you’re supposed to wear it! All finishers will get an ugly sweater race medal, a themed shirt and a finish line expo with vendors, food and cookies.
