Embrace the rugged charm of winter trail running at the Ugly Mudder 10K Trail Run, set for February 1, 2026, in Reading, PA. This race, renowned for its challenging yet achievable course, promises an experience that lives up to its name, attracting a field limit of 250 runners annually. Hosted by Pretzel City Sports since 2004, the Ugly Mudder delivers a truly authentic trail experience.

The 10K course, with 95% un-paved trails, traverses rustic terrain laden with rocks, roots, and leaves, featuring both single and double track sections. While there's only one truly significant hill, don't mistake that for an easy ride; runners consistently note that the race "runs a lot tougher than its listed distance." Expect "toe-stubbers," downed trees, and plenty of ups and downs, periodically interspersed with glimpses of scenic woodland beauty. Typical race day conditions in early February present highs around 39F and lows around 22F, with an 11% chance of precipitation, ensuring you might just find that eponymous mud.

Beyond the challenging trails, the Ugly Mudder offers a memorable race atmosphere. Participants will find a well-marked course and unique aid stations featuring alternate beverages to keep spirits high. The start and finish are conveniently located at the Reading Liederkranz German Singing & Sports Club, 140 Spook Lane, Reading, PA, where all pre and post-race activities, including registration, are held. After conquering the "ugly" trails, runners can enjoy hot and cold grub and a cash bar in a covered finishing area, making for a truly satisfying conclusion to this distinctive winter trail adventure.
