About this race
The Inferno Challenge Harns Marsh dares you to take on the sun, sweat, and Florida fire. The course is flat and fast, but the real test is handling the heat. This race pushes limits with gritty summer miles through Florida's sun-soaked terrain, designed for endurance athletes and heat-hardened runners.
