THE HELLHOLE GRAVEL GRIND STAGE RACE & 1-DAY GRAVEL FONDO
The Hellhole Gravel Grind features a weekend of gravel and offers multiple events geared toward riders of all abilities held entirely within the confines of the Francis Marion National Forest near Charleston, SC.
The pinnacle event, a three-day stage, is the first and longest running gravel stage race in the United States. Featuring nearly 150 miles of gravel, the race begins with a one-of-a-kind night-time prologue showcasing competitors under the twilight of the forest canopy. The weekend also features 42 and 75-mile gravel fondo options for those inclined.
Despite being pancake flat, this unique event will test riders' physical and mental toughness. The hundreds of miles roads of the Francis Marion are mostly hard-packed gravel, with some grassy doubletrack, Roubaix-rated trail sections along the Palmetto Trail and megafauna such as bear, snakes, boar (and chupacabra…).
The event is promoted by Mt. Pleasant Velo and has been featured in Cyclocross Magazine, Bicycling Magazine, Mens Journal, and Gravel Cyclist. The event is quickly becoming a marquee gravel event and should be on any gravel enthusiast's bucket list!
Race Notes and Information
The Hellhole Gravel Grind Prologue, 2-Day Stage Race and 1-Day Gravel Fondos 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”.
Event Schedule: (all stages begin at Witherbee Ranger Station)

1-Day Gravel Fondos
For those less ambitious, there will be a 1-Day 75 mile, long course and 42 mile, short course ride on the first day of the Stage Race. The 75 mile course will be the same as the first stage of the stage race. The 42 mile ride will feature approximately 35 miles of the 75 mile course before splitting off and returning to the start/finish area. The 42 mile ride will be timed.
Stocked aid stations will be available on each day’s course and limited support will be provided along the courses. To say this area is remote is an understatement. Bring with you what you think you may need for before, during, and after the race.
Stage Race - Riders must reach the mid-point aid station within 3.5 hours and must complete each day’s stage within 7 hours.
75 Mile Fondo - Riders must reach the mid-point aid station within 3.5 hours and must complete the course within 7 hours.
