No Business 100

The No Business 100 is a challenging 100-mile ultramarathon held annually in October, based out of Pickett CCC Memorial State Park in Jamestown, Tennessee. The single-loop course features approximately 14,500 feet of ascent and descent, traversing scenic trails through the Big South Fork National River & Recreation Area, crossing between Tennessee and Kentucky. Known for its picturesque and remote terrain, the race reverses direction each year and includes 15 aid stations along the route.

With a 34-hour cutoff, the event offers a rugged and immersive trail running experience and serves as an official qualifier for the Western States 100. Visit the organization's website for the most recent information.
