In short, Grinduro is just what it sounds like: Gravel Grinder + 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 celebration of cycling with as much emphasis on the party as the ride, with excellent food, an impressive display of art and incredible handmade bikes, live music, free camping and a festival atmosphere.
The course is a serious affair (8,000-feet of climbing in 65 miles) but the Grinduro isn’t meant to be a sufferfest. We’ve linked together some of our favorite roads in a quiet corner of California’s Sierra Nevada Mountains. The course features a mix of surfaces (smooth pavement, gravel and hard-packed dirt) with two main climbs, one long valley and two world-class descents. One descent includes a fast, smooth and flowy singletrack trail. The other is 30 miles of sustained descending!
