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 began posting 2023 dates as they trickle in!
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.

What started as a small thing back in 2015 blossomed into THE resource for mountain bike racing in Colorado and Wyoming. So as expected, hosting costs and maintaining the website takes more time and money to keep it updated. Any support will be greatly appreciated!

no date yet, but when it comes up the Laramie Roubaix (Gravel Grinder – ish) could be added. http://www.laramiebikenet.org/laramie-roubaix.html
Awesome, I’ll definitely add it when it comes up!

This is the registration page for the WYOCITY American Mountain Bike Challenge in Casper. http://www.usacycling.org/events/index.php?event=1127&year=2015
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…
Thank you, looks like the date is set for Ring The Peak, Sept. 3rd. And Banana Belt in Salida Sept. 17th.
Thank you! I’ll get those updated!
Great list Heidi! How about the Epic series in WP? I see that you had it listed in 2015…
Thank you! Last time I checked there was no 2016 dates available. Many of the smaller series don’t have their dates this early in the year. I go through every few weeks and check for updates!
Oskar Blues Old Man Winter – Lyons, CO – 50k/100k loops. 2/7/16 http://oldmanwinterrally.com

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.
You’re welcome! And definitely we can collaborate! 🙂
A good race to add to your list is the Dakota 5-0, very popular with the Fort Collins crowd. http://www.dakotafiveo.com Sept 3, 2017.
I am sticking to just races located in Wyoming or Colorado. I thought about expanding out, but then it would be just too much to keep track of.
Thanks for making this available! great work.

I love this, thank you so much. I’ve decided to do my first enduro race this year (aaahh scary and exciting). It’s exhausting looking for enduro races in Colorado so I made my own list!
Check it out here! http://www.mountainbikeevent.com/2017-colorado-enduro-race-list/
I will like to your site for all other races!
Awesome! I think I’ll just post your link up top to direct enduro people your way 🙂 It’s so hard to keep on top of all these races!
2017 Mountains Revenge will be under the full moon again August 5th-6th. And it will be based on Main St. Montezuma just like the original! Thanks for all the calendar work Heidi!

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.
Hi! I am unsure if I’ll go through all the work again for 2018, as I’m not racing very much. But maybe! 🙂
We have a sick XC course Idea in the colorado springs / Monument area. Do you have any desire to have a race near springs?
keith at firstname.lastname@example.org
Hi! I have done a few races down that way. I am unsure how much I’ll be racing in 2018, but always will entertain the thought of new races in new places!
First I want to thanks a lot to this guy how help to make this awesome list. This is really helpful for all.
Hello Heidi!! This list is great!! Will you be making a 2018 list as well? Thanks again!!

You’re missing the Steamboat Stinger. Great list! Very helpful.
Thank you for pointing that out! No idea how I missed that one on the 2020 list!
Laramie Range Epic website is https://www.laramierangeepic.com/
The old one listed looks like a creepy spammer site.
Thank you! I had forgotten to update it from the old Laramie Enduro site. Too bad they didn’t keep the domain and just redirect it, because that race will be known as the Laramie Enduro to so many of us permanently!
You should definitely add the Drift (13/28/100) fat bike race. http://www.thedrift100.com/100-mile-course/
Thanks! Got it added!
