FSR 100 - Copperhill, TN

FSR 100 - Copperhill, TN takes place in McCaysville, Georgia, on October 17, 2026, put on by Project 42 Running. A single format is offered: a 100-mile trail race starting at 6 a.m., in the mountains along the Georgia and Tennessee state line near Copperhill.

A hundred-miler in these mountains is a full commitment. You start in the dark, you run through a full night, and for most finishers the clock stops well into the following day. That means a crew or drop-bag plan, a headlamp system with backup batteries, and a stomach you have trained to accept calories after fifteen hours of effort. Runners typically arrive with a 50-mile or 100K finish already behind them and a 20-week block built around high-volume weekends and long climbing sessions rather than speed work.
