About this race

Come run the No Business 100 October 23-24, 2026. This beautiful autumn race treats runners to miles of technical single-track trails and scenic landmarks. The 2026 No Business 100 is also a qualifying race for the 2027 Western States Endurance Race.

The No Business Hundred is a trail endurance race that begins and ends at the Group Camp in Pickett CCC Memorial State Park. The course is a single 100+ mile loop that traverses through the heart of the Big South Fork National River & Recreation Area starting in Tennessee then crossing the state line into Kentucky and back on some of the oldest trails in the southeast. We reverse the direction of the course each year and award a special buckle for runners who complete the course in both directions.

Along the way participants will pass through towering sandstone arches & rockhouses, gaze upon spectacular overlooks & waterfalls, and visit abandoned farms and homesteads including the No Business settlement. This epic journey is an adventure through some of the most scenic and wild areas in the region.

With just over 14,500 feet of elevation gain, the No Business Hundred may appear at first glance to be a walk in the park but make no mistake, the technical terrain and remote setting present a challenge that make it a unique hundred mile course.

*There is a 34 hour cutoff for this race in both directions.
