Grinduro returns to beautiful Mt. Shasta in 2023: May 19 - 21

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.

Grinduro California is brought to life by founding and host sponsor Giro, plus global partners SRAM, Zipp, TIME, EVOC Sports, and komoot.
