Mississippi 50

Honoring founder Carl Touchstone, who moved the race to the Longleaf Horse Trails in DeSoto National Forest in 1996, the Mississippi Trail Run added its 100-mile distance in 2023 — the first 100-miler in the state. The course loops through gently rolling pine forest on single-track and logging roads: seven 12.6-mile loops plus two 6.1-mile loops, with creek crossings that can run knee-deep after rain. The 100-mile starts Friday at noon with a 30-hour cutoff; the race director puts the drop rate near 50 percent.
