In 2015 the Grinduro event concept was brought to life in a joint venture between Giro Sport Design and Sierra Buttes Trail Stewardship. SBTS were able to realise the dream of Grinduro and the rest as they say is history.
Voted “Event of the Year” by the Design and Innovation Awards committee, in 2019 Grinduro expands into four countries. The unique format of Grinduro combines the best elements of a mountain bike enduro with a gravel grinder-style road race. Festivities include two days of excellent food, a handmade bike show, an art exhibit, live music and camping.
The event is produced by Sierra Buttes Trail Stewardship supported by Giro Sport Design, Rapha, Maxxis, Fabric and your event host Cannondale.
Quincy, California, is located in the northwestern Sierra mountains. It began as a Gold Rush community in 1858. The downtown area offers quaint coffee shops, restaurants, bars and art galleries.
The closest major airport is Reno-Tahoe International, about 1.5 hours away followed by Sacramento and SFO. Bay Area residents should plan on a scenic, four to five hour drive.

In short, Grinduro is just what the name suggests: Gravel Road Race + Mountain Bike-Style Enduro = one long loop of pavement and dirt, where finishing times aren’t based on overall loop time, but four timed segments (each roughly five-to-ten minutes).
But Grinduro is not just a bike race. It’s a celebration of cycling with as much emphasis on the fun as the ride, with excellent food, an impressive display of art and incredible handmade bikes, live music, camping and a festival atmosphere.
The course is a serious affair (7,500-feet of climbing in 60 miles) but the Grinduro isn’t meant to be a sufferfest. We’ve linked together some of our favorite roads in a quiet corner of California’s Sierra Nevada Mountains. The course features a mix of surfaces (smooth pavement, gravel and hard-packed dirt) with two main climbs, one long valley and two world-class descents. One descent includes a fast and flowy singletrack trail. The other descent trends downhill for 30 miles!
With a Gran Fondo-style mass start from Quincy, you’ll be pedaling out of town and up the first climb alongside your heroes and the pace will be conversational—because overall time doesn’t matter, only the four timed segments. The Grinduro segments are designed to reward the most well rounded of rouleurs.
Not quite as challenging, but a healthy bite of the Grinduro experience - Grindurito for 2019 will be roughly one half of the challenge of Grinduro without the competition. Ride up the Grizzy Peak climb with your friends, and cut back towards Quincy before the descent to Genesee and the long climb back to Quincy. At roughly 30-miles and 4000” of climbing, Grindurito is solid alternative if your legs aren’t quite ready for the full course.
Did you ever want to donate to building and maintaining more trails? You just did.
Your Grinduro CA race entry supports the Sierra Buttes Trail Stewardship - a non-profit organization that builds and maintains multiuse trails in the Sierra Buttes, Tahoe, Plumas and Lassen National Forests. Our mission is build sustainable recreation-based communities through stewardship, job creation and hosting three world-class events. Providing quality outdoor experiences through trail construction and maintenance in the Lost Sierra is what we are all about.
Proceeds from all three Sierra Buttes Trail Stewardship (SBTS) events – Lost and Found Gravel Grinder, Downieville Classic, and Grinduro – feed back into SBTS to help fund trail building and maintenance. Some trails can be built by grants that we apply for, but others cannot. So, our events are fundraisers to create privately funded – and wickedly fun – high alpine trails that dart through the forest. During the race, you’ll be enjoying our fine singletrack creations, and the vibe you’ll experience thanks to your race hosts, SBTS.
We appreciate your support, and we invite you become a member of our organization – our Tribe.
Got a Tent? We love campers! So there are plenty of grassy areas and tucked-away spots for your tent. And if you’re registered to ride, camping is included at no additional charge. Note: A campsite is limited to 1 tent and no hook-ups are included.
Got an Adventuremobile? If you plan to camp with your vehicle (no RVs or anything over 25’) we have a dedicated camping area for your vans, truck campers, roof top tents and other cool rigs. And if you’re registered to ride, camping is included at no additional charge. Note: A campsite is limited to 1 small vehicle (under 25’) and no hook-ups are included.
We believe that bike riders’ health, attitude and performance is directly related to the foods that they eat, so we have amazing food planned for the weekend. Breakfast, lunch and dinner are all included with race entry on race day. For the rest of the weekend we will have various vendors on site selling food.

The Grinduro course features a blend of pavement, dirt road, gravel road and singletrack.
More rules and common sense:
Be cool, have fun and enjoy the ride. Those are the rules!
For those of you who need things spelled-out, here you have it…
THE BEST BIKE: You can ride any type of pedal-driven bicycle (no electric-pedal assist!), although we recommend a cyclocross bike or mountain bike for the Grinduro course. The ultimate setup is probably a disc brake-equipped cyclocross bike with fast-rolling, tubeless clincher tires. For the Grindurito, many suggested a mountain bike to better enjoy the semi-technical singletrack descent down Mount Hough Trail. Be prepared with at least two extra tubes, a multi-tool and mini-pump.
A WORD OF WARNING: It’s rough in the Sierra Nevada Mountains. Seriously rough. On a course pre-ride once, we had nine flats with one flat on a 4×4 Toyota truck and one on a Mercedes wagon. If you come out on your road bike with inner tubes in your tires, you’re almost guaranteed to end up finishing on foot, if at all.
We’ll be at high elevation in the fall, so bring layers—ideally arm/leg warmers and a jacket—just in case weather rolls in.
There will be feed zones (and an excellent lunch!), but smart riders will bring at least two water bottles and their favorite nutritional supplies.
You can ride this loop in road shoes with road pedals, but we recommend mountain bike pedals and shoes for their versatility.
And don’t take the start line without a helmet on!
Grinduro’s Art and Bike Show is basically a curated collection of our favorite, mostly-bike-related things. It’s two parts handmade bicycle display, one part art exhibit, one part independent craft fair and one part bike shop.
It includes some of the most interesting and elaborate works of art in cycling. We showcase the independent artisans and the iconoclasts who rarely get the spotlight at traditional trade shows and bike events. In addition to the bike exhibit, we’ll have work on display from some of our favorite artists, photographers and craftsmen.
We have a host of custom bike manufacturers coming to our Pop-Up Shop this year, including:
In addition to fame and glory each winner will take home a little something special. Best of luck!
