About the Race
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.

Common questions
How hard is the Ugly Sweater 5K 5K?
We don't have a verified elevation profile yet — check the organizer's course map for the climb breakdown.
What should I wear?
Dress for ~10°F warmer than the standing temperature once you start running. Throwaway long-sleeve at the start, gloves and a hat for sub-50°F mornings, singlet plus visor when it climbs above 60°F. The race-day forecast above is the source of truth closer to the date.
When does it sell out?
No published deadline. Most races raise the entry fee in tiers and can sell out without warning — sign up early if you're committed.
