From Race Director Justin Mace: “Its the O.G. of Cohutta 100 courses! The year’s Cohutta 100 will use the singletrack section of Brush Creek and the Tanasi trail systems but then will go into a huge gravel loop known as “The Death March”. After the Death March you’ll head back into single track to get you to the finish line for some food and a warm hug. Total elevation is 12,000+.”
