Prepare for an unforgettable journey into the heart of Missouri's rolling landscapes at the Ozark Foothills Endurance Runs, set for April 10, 2026, in Wildwood, MO. This event, hosted annually at Greensfelder County Park, promises a true test of grit and spirit, offering a wide array of distances including 100M, 100K, 50M, 50K, a unique Night-50K, Marathon (26.2M), 25K, and a 25K RUCK, alongside a 1-Mile Kids Fun Run. Known for its challenging and scenic terrain, the looped course is predominantly single-track, weaving through steep grades, technical rolling hills, roots, rocks, and creek crossings that demand your full attention. You'll navigate a hilly course with elevation gains ranging from 1,700 feet for the 25K to a formidable 14,000 feet for the 100-mile distance, all set against the backdrop of the picturesque Ozark Mountain foothills.

Runners consistently praise the Ozark Foothills Endurance Runs for its laid-back, old-school ultra atmosphere and the exceptional support provided by its volunteers. The race is committed to sustainability, operating as a "cup-free" event and requesting participants bring their own reusable mess kits to minimize waste. Aid stations are strategically placed, offering ample support, though runners are advised to carry a minimum of 32 to 64 ounces of water between stops. Typical race day conditions in April offer comfortable highs around 67°F and lows around 42°F, with a 19% chance of precipitation, though spring weather can be unpredictable, occasionally adding mud and challenging footing to the mix.

Beyond the physical challenge, the Ozark Foothills Endurance Runs stands out for its inclusive spirit, participating in the Trail Mix Fund to waive registration fees for BIPOC and LGBTQ+ communities and those facing financial barriers. Loyal participants can even join the Ozark Foothills 500 Miles Club, earning a custom puffy jacket upon accumulating 500 race miles. With its well-marked, technical trails and vibrant community, this race is more than just an endurance event; it's an opportunity to test your limits and experience the beauty of the Ozarks.
