The Ugly Sweater 5k
About this race
The Ugly Sweater 5K 🎄🦌🎰
Break out your holiday spirit—and your questionable fashion choices—for The Ugly Sweater 5K!
Join Red Rock Running Company on Saturday, December 19 at 8:00am at Floyd Lamb Park for a festive 5K filled with holiday cheer, ugly sweaters, and a little Las Vegas flair. Whether you're racing for a PR, jogging with friends, or just here to show off the ugliest sweater you can find, this is the perfect way to celebrate the season.
This year's theme is “Santa Lost Everything at the Casino”—apparently Rudolph and the crew are going to have to run home. 🎅🎲🦌
Every participant receives an Ugly Sweater 5K finisher medal and an ugly sweater-themed long-sleeve tech shirt that's designed to be every bit as ridiculous as the event itself.
Come dressed festive, come dressed ugly, and get ready for 3.1 miles of holiday fun at Floyd Lamb Park!
