Prepare to confront a legend at The PIASA, Presented by the Wildcat River Runners on May 9, 2026. While proudly presented by St. Louis, MO, the true challenge unfolds amidst the rugged bluffs and forested ravines of Pere Marquette State Park in Grafton, IL. Runners can choose their reckoning across 50K, 25K, and 12.5K distances, each designed to push limits and test resilience. This race draws its spirit from the mythical Piasa, an Illiniwek (Algonquian) beast, often translated as "the bird that devours men," said to have haunted these very cliffs. It's a confrontation not just with the terrain, but with the legend itself.

The course is notorious for its technical footing, demanding descents, and relentless climbs; "short climbs don't exist here". Those tackling the 50K should brace for over 4,000 feet of buckle-worthy climbing, a true test of endurance and will. The beautiful scenery of the park serves as a deceptive lure, promising breathtaking views while simultaneously demanding sustained effort from every participant. Typical race day conditions in early May feature comfortable highs around 74°F and lows around 54°F, with only an 18% chance of precipitation, offering favorable weather for an epic trail adventure.

What truly sets The PIASA apart is its unique challenge, culminating in the 50K’s "Solo" or "Buddy Division" options. The Buddy Division fosters shared suffering and shared victory, as two runners navigate the course together, proving that sometimes, conquering the Piasa is not a solitary journey. While specific aid station details will be released closer to race day, runners can anticipate well-supported stops, typical of such demanding ultra-events. This race is for those who seek to earn their finish, leaving everything on trails that truly do not relent.
