Grinduro California, the favored gravel get together with a race within the center that additionally advantages a neighborhood outside nonprofit, returns this yr for an additional installment of the experience that tells “a story of two sides” of Mt. Shasta.
For race organizers, the secret this yr is getting butts on saddles. To that finish, they’ve excitedly introduced there’s no snow “anyplace” on the 59.1-mile course, and that wildflowers are “exploding.” Additionally, there’s no hike-a-bike on this journey, which organizers stated will embolden some however “admittedly chagrin” others.
The weekend runs Could 19-21, with races on Saturday sandwiched between assorted revelry and ancillary rides. Organizers prolonged the registration deadline in a remaining bid to fill out the grid.
“Riders will expertise every little thing from tough distant gravel roads to clean swoopy singletrack, all between an elevation of three,500-5,000 toes to remain out of the snowpack,” a press launch stated.

Course co-designer Dave Tricamo dove in additional.
“The Grinduro course is available in at 59.1 miles with 21 of these paved and 6,325 ft. of elevation achieve. Don’t be misled by the mileage, this can be a robust course with relentless adjustments in elevation and a large number of floor varieties that can hold riders on their toes. And as for the most essential of issues, tire kind and stress! I’d experience a 40C tire with some knobs at about 40 PSI. This isn’t a mountain bike course,” Tricamo suggested.

Racing takes place Saturday, Could 20. Roughly talking, the course leads riders from clean, extensive roads in timber nation south of Mt. Shasta to a steep, zigzagging singletrack end. Alongside the best way, there’s scenic personal property Grinduro obtained particular permission to experience, plus some difficult gravel climbs, and an idyllic lunch on the Lake Siskiyou shores.
A shorter choice, Grindurito, appeals to riders much less skilled or out for a lark. At 35.5 miles and three,546 ft. of climbing, it encompasses Grinduro levels 2-4.
The three-day occasion additionally contains preliminaries on Friday, and the “Wahoo Hangover Journey” on Sunday — plus loads of “maxin’ and relaxin’” within the type of tenting, dwell music, meals, and “competition vibes.” For routes, GPX information, and all accessible course particulars, take a look at the course maps website.

And oh, yeah, your cash goes to a trigger that seeks to guard actions like gravel using within the space. The occasion advantages its organizer, the Siskiyou Outside Recreation Alliance (SORA). The nonprofit is “centered on selling sustainable outside recreation by packages, coverage, planning, and stewardship,” the press launch stated. Funds from every Grinduro, it added, go instantly towards path upkeep and development for the next yr’s race.
There’s even a funding stream that advantages low-income households within the space who might need to get out within the mountains, however don’t have the assets.
