Prepare for an unforgettable journey through Missouri's Mark Twain National Forest at the Ozark Trail 100 Mile Endurance Run, a demanding point-to-point ultramarathon taking place on October 31, 2026, with headquarters and the finish line at Bass River Resort in Steelville. This celebrated event, recognized as the 2026 Missouri RRCA State Ultra Championship, challenges runners with 101 miles of primarily single-track trail, featuring approximately 12,000 to 15,000 feet of elevation gain. The course navigates through pristine wilderness, offering breathtaking autumn scenery, but demands respect with its varied terrain—from smooth dirt paths to moderately technical sections often obscured by a thick carpet of fallen leaves, along with numerous water crossings that can be knee-deep depending on recent rainfall.

The Ozark Trail 100 has earned a reputation as a deceptively difficult race, with a challenging course that has historically seen lower finisher rates. Runners consistently praise the race for its detailed organization, the supportive "trail angels" staffing the 13 fully-stocked aid stations (some offering hot food at night), and the coveted belt buckle awaiting all sub-32-hour finishers. Typical race day conditions in late October often see highs around 63°F and lows around 41°F, with a 13% chance of precipitation, though participants should be prepared for unpredictable weather, including the possibility of colder, wetter conditions. This intimate event promises a true wilderness adventure, where the beauty of the Ozarks meets the grit of ultra-running, fostering a strong sense of community among those who dare to tackle its legendary miles.
