Sweaty Sweater 5k

Sweaty Sweater 5k is a holiday running sporting event on Saturday, December 19, 2026, at Front Range Community College, 4616 S. Shields Street in Fort Collins. The organizer invites everyone to wear their most hideous, outrageous and unforgettable ugly sweater, though there are no pace or sweater requirements. Walkers, runners racing for an award and families are all welcome.

The 5K Run/Walk starts at 9:00 AM. The course starts and finishes at Front Range Community College and runs through the Clarendon Hills neighborhood, with about 162 feet of climbing and one aid station near mile 1.5. A Kids 1-Mile for ages 12 and under starts at 10:00 AM with its own start and finish.

Race day check-in opens at 8:00 AM, and awards follow at 10:15 AM, with overall, age group and team awards. Packet pickup is Friday, December 18, from 4:00 to 6:00 PM at Runners Roost Fort Collins, and race-morning pickup is also available. A virtual 5K is offered too.

At the finish there are cookies, donuts, holiday treats, coffee and hot chocolate, plus a postcard station. All participants receive sweaty sweater gloves. Leashed dogs and strollers are welcome.

The race is part of the Front Range Freeze winter series, along with the Polar Bear Run & Plunge on January 23, 2027 and the Sharin’ O’ The Green 5K on March 6, 2027. Finishing all three earns a series finisher prize. Register through the race’s RunSignup page.
