September 12th,
Mt. Shasta

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, camping, and more!

For 2020, Grinduro California is headed to an incredible new location… At the top of California lies the town of Mt. Shasta—a place uniquely touched by all four seasons and watched over by a legendary 14,179’ snow-capped mountain. Trust us that Mt. Shasta is going to make for a very special Grinduro.

The event is hosted by Evil Bicycles and supported by Giro Sport Design, SRAM, Maxxis, CyclingTips .
