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.

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.

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

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! 🌿🦌🦬
