A weekend of racing and partying in the Lost Sierra where riders can race Grinduro on Saturday, the Mt. Hough Enduro MTB/e-MTB Enduro Sunday, or both for serious bragging rights. 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. The Mt. Hough Enduro is a blind-format race, which means racers won't see the timed segments until they roll up to 'em.
Both races take place on Mt. Hough, which has developed into a singletrack destination over the last 10 years, now boasting more than 70 miles of mostly flowy singletrack thanks to the work of the Sierra Buttes Trail Stewardship, the organization your race entry fees support!
