The pioneering Grinduro format returns to its roots with a celebrated California gravel race in the quiet landscapes of the Sierra Nevada Mountains. Born in 2015, this event fuses the timed-segment excitement of mountain bike enduro with the endurance of a gravel grinder. The result is a unique experience where the ride unfolds at a conversational pace between four distinct timed stages, allowing the atmosphere and scenery to take centre stage. It’s a format designed to reward the most well-rounded rider, not just the fastest over the full distance.

The main loop is a serious and rewarding undertaking, tracing a 51-mile course with approximately 7,200 feet of elevation gain. The route begins with a Gran Fondo-style mass start from the town of Quincy, weaving together some of the area's best-loved roads. Riders can expect a true mix of surfaces under their tyres, from smooth pavement and quiet gravel to hard-packed dirt roads and even sections of freshly built, flowing singletrack. The profile is defined by three significant climbs and one long, scenic valley traverse.

For those seeking a taste of the Grinduro experience with a little less sting, the 'Grindurito' offers a shorter but equally engaging option. This 23-mile route accumulates a respectable 3,000 feet of climbing. While it’s a non-competitive format overall, it still includes two timed segments — a punchy climb and a flowing singletrack descent — for riders to test their legs and handling skills. It serves as a perfect introduction to this unique style of California gravel race or for those building their endurance.

More than just a race, Grinduro is a weekend-long celebration of cycling culture, held at the Plumas-Sierra County Fairgrounds in Quincy. The event is known for achieving the perfect party-to-race ratio, creating a festival atmosphere that lasts all weekend. Participants can enjoy live music, a handbuilt bike show, and an expo featuring industry brands. The sense of community is a core part of the experience, with camping included and shared meals fostering connection off the bike.

Set against the backdrop of the northwestern Sierra mountains, Quincy is a historic Gold Rush town that provides a welcoming base for the event. The area’s character is shaped by its forested hills and quiet roads, making it an ideal setting for this California gravel race. The course showcases the region’s natural beauty, from challenging ascents to world-class descents that reward every foot of climbing. It’s a ride that connects participants to the landscape in a tangible way.

The weekend is designed to be a complete experience, with amenities like breakfast and dinner included on race day, feed zones, and on-course technical support. The combination of a challenging course, a unique competitive format, and a vibrant festival atmosphere makes Grinduro a standout event.
