The Hellhole Gravel Grind Prologue, 2-Day Stage Race and 1-Day Gravel Fondo will take place on the gravel roads in and around Hellhole Swamp in the Francis Marion National Forest just outside of Charleston, South Carolina. The forest is named for the revolutionary war hero Francis Marion, who was known to the British as the Swamp Fox. He used these swamps, creeks and forest areas to ambush and hide from the British and was depicted in the movie “The Patriot”.
