Grinduro Returns Home: The Ultimate Gravel Party Back in Quincy
After 5 years in Mt. Shasta, Grinduro is making its much anticipated return to where it all began - Quincy, California. Mark your calendars for September 11-14, 2025, as we'll be heading to Mount Hough to join the celebration of this groundbreaking event's 10th anniversary.
Sierra Buttes Trail Stewardship, the original creators of this revolutionary gravel-enduro format, are partnering with Breakaway Promotions to bring the party back to the Sierra-Plumas County Fairgrounds. The legendary course features the Mount Hough Trail - a breathtaking 12-mile, 4,000-foot descent of pure flowing singletrack.
As Greg Williams, executive director of SBTS, perfectly puts it: "Bringing back Grinduro to Quincy in its 10th year feels like the perfect pairing at the perfect time."
We can't wait to join the party and finally have the chance to experience Grinduro where it all began.
Registration Opens: March 16, 8PM PST
