Qualifier status per the 2026 lists
Founded in 2017 by Ultranaut Running, No Business 100 covers 102 miles through the remote Big South Fork National River & Recreation Area — starting in Tennessee, crossing into Kentucky, and looping back — with 14,500 feet of gain on technical singletrack past sandstone arches, rockhouses, waterfalls, and the abandoned No Business settlement. Spot trackers are mandatory; the longest gap between aid stations is 7.6 miles. The course reverses direction annually, with a special buckle for runners who finish both ways. The 34-hour cutoff is tight for the terrain; it is a Western States qualifier.
