No Business 100

The No Business 100 is a challenging 102-mile trail ultramarathon held annually in October, starting and finishing at Pickett CCC Memorial State Park in Jamestown, Tennessee. The single-loop course traverses the scenic and remote Big South Fork National River & Recreation Area, crossing between Tennessee and Kentucky. Featuring approximately 14,500 feet of elevation gain, the race offers technical single-track trails, sandstone arches, rockhouses, waterfalls, and historic homesteads, including the No Business settlement.

The course direction reverses each year, with a special buckle awarded to runners completing both directions. With a 34-hour cutoff, the event is a qualifier for the prestigious Western States 100. Visit the organization's website for the most recent information.
