No Business 100

The No Business 100 is a single 102-mile loop out of the Group Camp at Pickett CCC Memorial State Park, north of Jamestown, Tennessee. It runs through the heart of the Big South Fork National River and Recreation Area, crossing into Kentucky and back, past sandstone arches and rockhouses, the Blue Heron mining community and the abandoned No Business settlement it is named after. The race reverses the direction of the course every year and gives a separate buckle to runners who have finished it both ways.

The 2026 edition starts at 8:00 a.m. Central on Friday, October 23 and closes at 6:00 p.m. on the Saturday, a 34-hour limit. Entry is straight sign-up on RunSignup, capped at 300 runners, and 2026 is full with a waiting list. A finish is a Western States 100 qualifier. Note the clocks: the race starts and finishes in the Central time zone while most of the course lies in Eastern.

A single 102-mile loop from the Group Camp at Pickett CCC Memorial State Park, with just over 14,500 feet of climbing on technical singletrack through the Big South Fork. The direction reverses each year, counter-clockwise in even years and clockwise in odd. Fourteen fully stocked aid stations sit on course besides the start and finish, six of them with crew access. All cut-offs are Central time even though most of the course runs in the Eastern zone.

Entry is first-come sign-up on RunSignup, with a cap of 300 runners and no lottery. The race states no qualifying requirement, though it recommends having completed at least a 50-mile race or training run in the same calendar year, and recommends volunteering without requiring it. The 2026 window opened at noon on February 12 and the race is now full; a first-come waiting list runs from there, with 48 hours to accept an invitation. There is no race-day entry and no transfer to another runner or year.
