Cowboy Crusher Rider Guide

Welcome to The Cowboy Crusher and beautiful Central Wyoming.

Are you ready to be Cowboy Tough!


We are super stoked to have you visit the wonderful town of Glenrock, Wyoming. We’ve worked hard to bring you an epic gravel experience that will keep you coming back year after year and bringing your dirt lovin, grit lovin, and gravel lovin friends!



LOCATION:  Glenrock Town Park  -    


This is where the shindig begins: Start/Finish, after party, awards, music, food, and a lota…lota…giveaways. We encourage you all to bring your friends and family to stay and play. There is a play-ground for the kids, and music and beverage for the adults. The park has ample parking, but NO CAMPING! Feel free to find a spot in the surrounding area where permitted.


PACKET PICK-UP: Due to limited lodging in Glenrock, there will be two packet pick-up locations. One in Glenrock, WY and one in Casper, WY.


  • Casper location: Fri July 12, 4:00 pm to 8:00 pm. Location TBD – watch for an email with more information. 

  • Glenrock location: Fri July 12, 4:00 pm to 8:00 pm at Glenrock Town Park.

  • Saturday July 13 - for those that cannot make it on the day before, you can pick up your packet and sign in 30 mins before your start time (please come on Friday if you are able, this will help keep the race day whirlwind to a minimum!).


What will be included in your packet: number plate with timing chip, meal ticket and drink voucher to use at the food vendors and beverage tent in the park.  A Cowboy Crusher t-shirt and plenty more swag.

There will be a lead-out vehicle at the start for each of the courses. Once that pulls away, the race is on. Keep your eyes open for the Cowboy Crusher signs as they clearly mark the courses throughout. It is the rider’s responsibility to know their way on the course. It is essential to download the appropriate course for your distance to your GPS device in advance. You’ll spend a large part of the day outside of cell coverage.

The GPX files are also available to load to your devices in the course info further down in this guide or directly on the website

Outside support is NOT allowed, except at the designated aid stations/checkpoints. The official aid stations/checkpoints along the routes will serve as a neutral area where event participants may meet their support crew to restock supplies and repair equipment. The official aid stations/checkpoints will be the only locations along any of the courses where participants may receive assistance from their support crew. Receiving assistance (other than immediate emergency medical needs) from a support crew, or any other non-participant, at any point other than the official aid stations/checkpoints will result in immediate disqualification from the event. There are no exceptions to this rule. Participants may help other participants with navigation, mechanical, or any other requested assistance.

Support Crews and/or spectators are NOT allowed on course. If you are going to abandon the race you must make it to an official aid station/checkpoint, and then call for your support crew to come get you or take a ride back to Glenrock with a SAG wagon when it is available. A Course Marshall or SAG wagon can take you to the next aid station/checkpoint if they are available. Providing support to a rider while on course is not in the spirit of self-sufficiency of grass roots gravel racing. It is also unfair to other participants, and increases the risks to other participants when there is more traffic on the road, and therefore will not be allowed. Please help us insure the safety of ALL participants by having your support crews meet you at official aid stations/ checkpoints ONLY.

If for some reason you abandon the race you MUST check in at the timing table to let event organizers know you are no longer on course



Mandatory Carry List

**Each participant must carry with them (on their body, or on their bike) the items on the mandatory carry list.**

  • Bike: hopefully, by race day you’ve chosen your trusty steed. Note: NO E-BIKES ALLOWED IN THE COWBOY 121 OR BRONCOBUSTER 75 COURSES.

  • Helmet: helmets are required to participate in this event and must be worn at all times when on the bike.

  • Cycling computer/GPS – GPS computer is required for the Cowboy 121 course and strongly encouraged for Broncobuster 75 course.

  • Rear taillight – visible from at least 50 ft away. (Front head light not required, but you may want to have a one for extra visibility).

  • 2-3 water bottles and/or a hydration pack.

  • Food – energy bars, gels, nuts, chews, salt tabs, etc.

  • Spare tubes, CO2 cartridge, pump or inflation system, tire levers, and a multi tool. We strongly encourage you to carry extra butt butter also.

Additional supplies you should consider

  • Extra clothing: arm/leg warmers and a wind vest and/or a rain jacket (anything can happen in the mountains). 

  • Clothes to change into post-ride: Your bottom will like you better if you don’t walk around in a sweaty, stinky chamois for hours after being in your kit all day,




GPX FILE Links for download to your personal device






There will be multiple places you can stop for snacks, hydration, shade, encouragement, a potty break, or anything else you may need.  There will be plenty of electrolyte mix and water to top off your bottles. Aid stations will have energy gels, chews, bars, real food, and mechanical and medical supplies. Also, toilets or porta potties will be at the Windy Ridge Road, Campbell Creek Campground, Spring Canyon Road and Ayers Natural Bridge aid stations.

Note: although there will be an array of snacks at each feed zone, we strongly encourage you to have some “safety snacks” in your pockets just in case. Being over-prepared is always better than wishing you had something before you bonk.

Each Aid station will have an air pump and some basic supplies. We strongly encourage all participants to know basic repair skills and advise everyone to come prepared with CO2 cartridges or their own pump and extra tubes in case of a flat. If you are still unable to make a repair, SAG support cars will be on course to assist you with minor mechanical issues.

Hopefully there will not be any medical issues, however, be assured that you have aid available, and each station will be stocked with first aid supplies, sunscreen, and staff to make sure everyone is safe and taken care of. If there is an emergency, please call 911 if you have cell service. Given that there is limited cell service, try to get someone to the nearest Feed Zone or find a course marshal to assist in helping you.




This is NOT a closed course! Please abide by the rules of the road the entire time you are out on course. Obey the flow of traffic, stop at stop signs, yield to pedestrians, and FOR YOUR OWN SAFETY STAY TO THE RIGHT SIDE OF THE ROAD. Please respect the riders around you at all times. Let’s keep this fun and accident-free. 


Keep it clean, please! DO NOT throw your gel packets, paper, plastic wrappers or any other garbage along the route. Pack it In…Pack it out! Thank you

There are prizes for the top 3 times on each course in each category. There will also be recognition of the top three places in each age category. Be sure to check results and stick around for awards at 5PM!





As you finish the Cowboy Crusher, you’ll be greeted at the finish line with the ringing of cow bells, a high five and a hardy Wahoo!!!.

The awards and prizes will start at 5:00 pm.
