2020/2021 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.  These are definitely weird times, if not a bit heartbreaking as we see our lives disrupted in all sorts of ways.  Stay healthy, wash those hands, and stay six feet away from each other!  Hoard bike parts, not TP.


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 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!)

    1. Thanks!

      Just curious, is there any reason why there’s not a women’s pro class? I have a friend who was thinking of coming with me and racing, but she holds a USAC pro license so it looks like there wouldn’t be a category she could do…


  1. Heidi, thanks for all the work. I’ve used your list to update 1st City Team regarding MTB races. I’ve created a worksheet with event registration deadlines and have also created an ical calendar. Let me know if you would like to collaborate/share lists. Cheers.


  2. Thanks for putting this together.. indispensable when planning out the race season. You might want to add the power-of-four race at Aspen
