ATLANTA’S BEST-KEPT CYCLING SECRET

The secret: it isn’t actually in Atlanta. It’s about 30 minutes south—where the drone of the interstate fades into the rustle of tall grass, the crackle of gravel, and the occasional whiff of honeysuckle on the breeze.

This is Dirty Sheets. And for one glorious fall day, it becomes the Dirty Sheets Gravel Grinder—a rough-and-ready celebration of dirt, grit, and pedal-powered punishment wrapped in rolling hills and Southern charm.

Hundreds of knobby tires will tear through the backroads as riders charge a loop known across the Southeast for its punchy climbs, unpredictable turns, and the kind of character-building chaos you don’t get on pavement. Think of it as Silk Sheets’ unruly counterpart—less refined, more rugged, and 100% unapologetic.

It’s not polished. It’s not easy. But tucked between the beatdown climbs and muddy crossings, you’ll find wide-open pastures, crooked fences, and big-sky moments that make the effort worth it. If you’re into Type 2 fun and courses with bite, Dirty Sheets doesn’t disappoint.

PICK YOUR CHALLENGE

100 miles of mixed-surface madness 62 miles of “What did I get myself into?” 22 miles of scenic rollin’ with a side of sass

Each course includes a curated blend of gravel, road, and just enough singletrack to keep things lively. Expect some off-camber corners, loose climbs, and moments that’ll test your grip—and your grit.

NEW FOR 2025

Start + Finish in Serenbe

This year, we’re rolling out from the flower fields of Serenbe. It’s scenic, unexpected, and sets the perfect tone for the ride ahead.

New Trail Sections

All routes now include a few freshly added sections of singletrack—built with love by MTB Atlanta. Just enough edge to shake things up, not enough to make you cry in front of your friends.

Camping Now Available

Make it a full weekend. Pitch your tent at MTB Atlanta HQ, just down the road from the start line. Expect fire pits, starry skies, and campfire stories that may or may not be true.

Friday Shakeout Ride

A laid-back gravel cruise to get the legs turning and the nerves settled. Details coming soon in the Ride Bible.

Sunday Coffee Ride

An even more chill ride with a cup of Joe in your bottles before you get in your car and head for home.
