One of the most well-respected trail races in the east, the Big South Fork Trail Race has attracted avid trail runners from throughout the region. Since its inception in the mid-1990's, Race Director Bobby Glenn has presented a trail racing classic suitable for hardcore ultra enthusiasts as well as road runners looking for a challenging introduction to off road running.

The course starts and ends at the John Litton General Slavens Trailhead. The first 1½ miles is paved and gravel, with the balance being a single track trail. After a short paved section to exit the campground, runners will follow the gravel road out of the campground area. After about 1 mile on the gravel, runners will enter the trail and descend through the John Litton Farm to the Litton/Slavens trail. Taking a left there, they continue 2½ miles to the Grand Gap Loop. Taking a right there, they follow the 6.8 mile Grand Gap Loop, and then return the entire 5.1 miles to the trailhead via the Litton/Slavens trail. Aid stations at (roughly) 3.5, 8.5, 12, and 14 miles. Course closes in 5 hours.

New in 2012 was a 10k option, a loop course that is primarily singletrack, that has been a hit and will again be offered for 2017.
