Event organizer

GRINDURO!

At its heart, the unique format of GRINDURO combines the best elements of a mountain bike enduro with a gravel grinder-style road race. But GRINDURO is not just another gravel race. It’s a weekend-long celebration of gravel cycling with as much emphasis on the fun as the ride. The magic happens when you add great food, an art & bike festival, high-quality music and camping in an epic location.
