No Business 100

The No Business 100 is a single loop 100 mile trail ultra. Each year, we reverse the direction of the course running it in the clockwise direction in even years and counter clockwise in odd years.

NB100 begins and ends at the abandoned coal mining town, Blue Heron Mining Community, just west of Stearns, Kentucky. The course traverses through the heart of the Big South Fork National River & Recreation Area across the state line into Tennessee and back on some of the oldest trails in the southeast.

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 over 14,000 ft of climbing and 14,000ft of decent, combined with the technical terrain make the No Business 100 a challenging and unique hundred mile course.

More details include the course map can be found on the official race website.

*In odd years, the course comes in at 101.9 miles and there is a 33 hour cutoff.
*In even years, the course is slightly longer at 104.9 miles and there will be a 35 hour cutoff.
