Welcome to the ultimate test of endurance. This isn’t your average Sunday morning jog in the park. We’re talking about a grueling 300, 200, and 100-mile race that will push you to your limits and beyond. But don’t let that scare you off, because trust us when we say, there’s nothing quite like conquering this challenge.

As you make your way through the picturesque Shelby Farms, surrounded by breathtaking landscapes and wildlife, you’ll find yourself questioning why you ever doubted yourself in the first place. The sense of accomplishment as you cross that finish line will be unlike anything else you’ve ever experienced.

But let’s not sugarcoat things here – this race is no walk in the park (pun)

Picture this: a trail that takes you on an adventure through a unique blend of terrains. It’s a wild mix of paved paths and thrilling single-track trails that wind their way through serene lakes and lush wooded landscapes. But hold on, it doesn’t stop there! As you traverse this extraordinary path, keep your eyes peeled for some unexpected company. Yes, we’re talking about the local wildlife – deer and even mighty buffalo sharing the trail with you! So gear up, embrace the untamed, and get ready to experience nature like never before. It’s time to hit the trail and embark on an unforgettable journey filled with breathtaking views and encounters with the wild side. Let’s go!

Our 33ish mile loop is a course designed to test your limits and ignite your inner competitor. Looking for something a little less intense or uniquely tailored to your goals? We also offer a 53k Friday the 13th night race distance for those ready to up their boundaries and a 25k option for runners seeking a challenging yet achievable feat.

Each distance represents an opportunity to grow, conquer, and redefine what you’re capable of. Whether you’re chasing a personal record or simply looking to push beyond your comfort zone, we’ve got the perfect course for your next adventure. Are you ready to take the leap?
