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!

2020 US OPEN Cancellation Updates:


Surreal times, as there is heavy impact across the globe from the COVID-19 (coronavirus) and the changes we’re all experiencing in daily life. Our MTB community is at the foundation of everything the US OPEN of Mountain Biking represents and we’re committed to doing right by you all. Every athlete, youth racer, family member, volunteer, spectator, event partner - contributes to the energy that creates the Fox US OPEN of Mountain Biking experience. We came into 2020 with unreal momentum and were excited and committed to building upon the US OPEN heritage. We've been hesitant to make any official announcement regarding the status of our events, hoping that things would come together for the USO Race Festival this fall. As we've watched so many major events around the world cancel, and after much careful consideration of the health and safety of our community, our global roster of athletes and partners - we're announcing that we will not be hosting the 2020 US Open Race Festival or Slopestyle competition. 

We'll sure miss the party with you all this year - rest assured we've already begun to work on 2021 US Open plans. Alongside the rest of our global MTB community, we will continue to do the best we can to keep the stoke alive and support our community as we navigate these times. While we can't promise anything, we are still looking at options to host regional Next Gen Youth MTB Tour stops for late 2020 - stay tuned. Thank you for all your support, we hope you're able to get out on your bike wherever you are in the world!
