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 I’m determined to try to solve that!
_____________________________
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!
Awaiting dates for… Leadville Big Friggin Loop, Ring the Peak, Banana Belt, rumors of a Lory State Park series
Laramie Mountain Bike Series is officially dead 😦
12 Hours of Penitence is not happening in 2021
No NBB short track in Spring 2021
(I pulled all these dates off of the official event websites. So any incorrect dates falls back on those websites, I merely just repeat the information. Please check official websites for any changes/cancellations – I will try to note when possible. Also several races on this list are lottery-entry, or sell out pretty darn quickly!)

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!
