The No Business Hundred is a single loop 100 miler on some of the most rugged and scenic trails in Kentucky and Tennessee. The race reverses the direction of the course each year with odd years being run clockwise and even years run counter clockwise from Blue Heron, an abandoned coal mining town.

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 14,000 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.
