Get ready for a unique trail running experience at the Madder Than A Wet Hen 5K, taking place on July 25, 2026, in Charleston, IL. This isn't just any 5K; it's a wild mid-year adventure, serving as the summer counterpart to the popular Frozen Cock's Crow 5K. Limited to just 125 participants, this event at Willenborg Woods is renowned for its intimate, quirky, and high-spirited atmosphere, drawing runners back year after year for its challenging course and unparalleled camaraderie.

Prepare for a demanding yet exhilarating run through winding forest trails, featuring approximately 1,100 feet of elevation gain packed into the 5K distance. The course's highlight, and perhaps its most talked-about feature, is a one-third mile stretch directly through the Embarras River, where in July the water typically ranges from ankle to knee deep, exposing sandy bars and rocky riffles. Just before the finish, runners face the infamous "Billy Goat Hill," a steep climb designed to test your grit. Typical race day conditions in late July include highs around 85F and lows around 66F, with a 12% chance of precipitation, so plan for warm weather and footwear ready for a good soaking.

Beyond the technical challenges and river crossings, the Madder Than A Wet Hen 5K promises a "more summer camp than serious race" vibe, fostering a strong sense of community. The event, held at 17737 E County Road 380N, culminates in a legendary post-race party complete with pancakes and ice cream—a well-earned reward after conquering this memorable course. Primitive tent camping is available on-site for those looking to extend the experience.
