No Business 100 : Jamestown, Tennessee (October 24-25, 2025)
The No Business 100 is the 9th annual running of a single-loop trail endurance race hosted from the Group Camp at Pickett CCC Memorial State Park in Jamestown, Tennessee. The course is about 102 miles with roughly 14,500 feet of ascent (and similar descent). The race crosses the state line into Kentucky and returns to Tennessee. The total race cutoff is 34 hours. The 2025 event is an official qualifier for the 2026 Western States Endurance Race. The organizers reverse the direction of the course each year and award a special buckle for runners who complete the course in both directions.
