2019 Colorado & Wyoming Mountain Bike Race List

After a one year hiatus…. it’s back!

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.  So I’m determined to try to solve that!  I know about most of the cross country and endurance races due to my detailed planning of my race season, so I might as well share that knowledge

If you know of a race not listed here, please comment so I can get it added! This is mostly a XC and endurance focus, but I might throw in the occasional enduro or downhill event on the list, along with fat bike events. I am slowly adding 2019 dates as they appear, so keep checking back!  I do not expect the calendar to even be near as complete as possible until late spring of ’19.. patience!

Waiting on dates for…  Colorado Endurance Series;  If you know of an event I have missed, please comment below with details/website.  This list is specifically for mountain bike events, though in the future I might branch out into a gravel calendar as well.  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.  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


  3. Heidi, I’m starting to see some 2018 dates for races. Are you going to put out a 2018 list? I really appreciate your hard work. Thank you.
