Join us for the festive Ugly Sweater 5K on Sunday, December 21, 2025, organized by HAL Sports! This joyful event will take place at the beautiful Washington Park in Denver, where runners and walkers of all ages can participate in a flat and fast 5K race. Embrace the holiday spirit by donning your most outrageous and tacky holiday sweater—think plenty of tinsel, bows, reindeer, and candy canes! It's all in good fun, and the more creative, the better!

As you cross the finish line, you'll be rewarded with an exclusive ugly sweater race medal and a themed shirt, celebrating your participation in this unique event. Plus, enjoy a lively finish line expo featuring vendors, delicious food, and scrumptious cookies! Don't miss out on this opportunity to kick off the holiday season with laughter, community, and a little bit of friendly competition. Sign up today and get ready to make some unforgettable memories!
