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 45 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 the Gravel Ride Podcast, Cyclocross Magazine, Bicycling Magazine, Men's 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”.

2-Day Stage Race
The 2-Day Stage Race will be approximately 75 miles each day and will feature a reversed course from day one. The courses will be ~90% of unpaved roads and trails (single and double track). This is a true stage race with the lowest cumulative time over the two days determining the overall winner.
1-Day Gravel Fondos
For those less ambitious, there will be a 1-Day 75 mile, long course and 45 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 45 mile ride will feature approximately 35 miles of the 75 mile course before splitting off and returning to the start/finish area. The 45 mile ride will be timed.
One stocked aid station 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.
Course Files (course will be released no sooner than two weeks prior to the event. We do not provide cue sheets for the route. You may print your own cue sheet if you want one as we do not provide them - we highly recommend installing the course map on your device of choice when made available)
