Fiery Gizzard Run

The Fiery Gizzard Run, held at Foster Falls State Park in Tennessee, features marathon, half marathon, and a 13-mile ruck-only event. The course is recognized as one of the Top 25 Trails in the US, showcasing waterfalls, rock formations, and scenic overlooks. Marathon runners complete the trail twice in an out-and-back format, while half marathoners traverse it once.

The trail combines mostly flat ridgeline running with several steep, technical descents into gorges, requiring careful footing. Aid stations are spaced 6-8 miles apart, so participants must carry sufficient supplies. The event supports trail maintenance, offers awards, and includes a rucking division with weighted packs.
