The Fox US Open of Mountain Biking was established in 2003 with the single goal of creating excitement in the American mountain bike scene.  Featuring a unique Open Pro/Am format, the Fox US Open offers the most challenging competition in the nation, setting the standard as a proving ground for up-and-coming and elite athletes alike. Anyone can enter the Open Class, and compete against pros for the massive cash purse and prove where they rank. Amateur athletes are after the bragging rights and some of the best prizes in racing.


Spectating is FREE, and we keep the bike park open to the public at all our events. Join the party and experience epic competition, spectating, and riding with friends!
