Grinduro is Back in 2023! Learn About Registration

Grinduro returns to Mt. Shasta May 19th-21st, 2023. Registration opens February 20th.

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 weekend long 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.

We are thrilled to bring Grinduro CA back to Mt. Shasta once again. We look forward to hosting 1,000 Grinduro racers, 150 Grindurito riders, plus friends, family, and the local community at Grinduro CA 2023–and we want as many NorCal riders to snag their entry spots as possible!
