2021 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 I’m determined to try to solve that!

If you know of a race not listed here, please comment so I can get it added! This is mostly a fat bike, XC, and endurance focused calendar, but I might throw in the occasional enduro or downhill event on the list.

____________________________

Thanks,  COVID-19.

I will work to update the calendar as needed with cancellations, date changes, etc, if I come across the information.  I highly highly HIGHLY recommend checking any race’s social media pages (Facebook, Instagram, etc) and official websites for updated information.

There are a lot of opinions about racing during COVID-19, both for and against.  I merely provide the race calendar, it is up to you to follow guidance, public health orders, instructions of the race promoters, and to decide your level of comfort with racing during the pandemic.

_____________________________

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 NICA, LMBS, lots of things

(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!)
