Colorado & Wyoming Mountain Bike Race Calendar

People are always complaining there’s not a comprehensive list of XC/endurance mountain bike races in Colorado and Wyoming… with so many promoters, it definitely can be hard and a lot of lists out there miss out on several big races and series (or ignore the awesomeness that is Wyoming mountain bike racing).  So here it is, the one many try to copy and rarely succeed… the one and the only comprehensive race calendar, big and small races alike, Wyoming included!  

I have been posting 2022 dates as they trickle in!  I have left the 2021 calendar at the bottom for reference as well.  


If you know of an event I have missed, please comment below with details/website.  This list is specifically for mountain bike events, please see my gravel calendar if the event is more that style.  Thanks!

I pulled all these dates off the official event websites and communications with race directors. Please check official websites for any changes/cancellations – I will try to note when possible, but sometimes I cannot keep up.  Also several races on this list are lottery-entry, or sell out pretty darn quickly, so always check websites for full registration details and processes.

    1. Thank you! I have it added. This definitely would fill an empty spot in July… but I must admit, I’d hesitant to register for anymore races due to the current state of events involving the pandemic and canceled events!
