The Dunes 50K
Welcome to the ultimate adventure at Jonathan Dickinson State Park, where the grueling trails will push you to your limits! This isn't your average run in the park. Our 50K and Heavy Half (14.4mile) courses will take you on an epic journey through 16 unique natural communities, covering over 11,000 acres of challenging terrain.
From the prairie wetlands to the Dunes of Heaven and Hell, you'll face some of the toughest obstacles nature can throw at you. The soft, rolling sugar sand dunes will test your willpower and endurance, pushing you to dig deep and find the strength to conquer the course.
But don't worry, this isn't a disorganized slog through the wilderness. Our expert team has meticulously planned every aspect of the event to ensure a super well-organized and unforgettable experience. We've limited spots for the 50K and Heavy Half races.
