Routes

Mutton Buster

17 mi · ↗ 1,000 ft · 75% gravel · $45 entry

Want to be a Cowboy?.....The Mutton Buster is your entry into the Cowboy life. 
This one is fast and fun right out of the gate. Follow in the footsteps of the Cowboy and Broncobuster as you pedal up the foothills of the Rocky Mountains. Then , just as you’re about to hit the step stuff, turn around , grab a handful of wool, and hold on as you rip back down into Glenrock and the finish line.
You will have a Wooly goodtime on this course

Buckaroo

40 mi · ↗ 3,100 ft · 60% gravel · $75 entry

Want a taste of the Cowboy life, but aren’t up for the bigger rides.
The Buckaroo is just enough tough to be Cowboy Tough!
This route is very scenic as it takes in the beauty of Mormon Canyon and the Boxelder Creek ranchlands just before you cruise down Boxelder Canyon with a smile on your face and back into Glenrock Park. The Buckaroo takes in parts of both the Cowboy 121and the Broncobuster 75 and will challenge anyone to be Cowboy Tough.
 

Broncobuster

75 mi · ↗ 6,600 ft · 80% gravel · $95 entry

It may not be the full-on Cowboy, but don’t be fooled, the Broncobuster is a Butt Kicker.
As you head southward and ascend Mormon Canyon you will start a conversation with yourself that goes something like this…”Wow, beautiful scenery”…”Wow, shut up legs”. Just keep pedaling and before you know it you are out of the canyon and feeling like you are on top of the world. Cruise through a few rollers and then head east down into the ranchlands of Boxelder Creek drainage. Enjoy the scenery of this ranching community until the course makes another turn down Windy Ridge Road and then northward towards Ayers Natural Bridge Park. Take in the scenery of the park and then mount your trusty stead and retrace your route back to the top of Windy Ridge Road and Boxelder Road. A few more mile of gravel and then you are on your way swooping down Boxelder Canyon back to Glenrock Park and the finish line.
 

Cowboy121

121 mi · ↗ 9,500 ft · 70% gravel · $110 entry

This route is NOT for beginners. It is tough and rough.
The Cowboy 121 takes you on a gravel experience like no other.
Experience the beauty of Mormon and Boxelder canyons as you ascend up the foothills of the Rocky Mountains. Views of the Shirley Basin await when you exit Upper Boxelder Canyon and loop eastward. A northward turn takes you down the La Prele Creek drainage and onto Cold Spring Road. Approximately 20 miles of pavement will give you a small reprieve until the route turns westward and runs past the Ayers Natural Bridge Park area. Soon you will start the climb back up toward Windy Ridge Road and lower Boxelder Canyon. Be sure to save a little in the tank for this climb as it is a doozy. Once back on top, you have a few more miles of gravel until the sweet descent down Boxelder Canyon and into Glenrock and across the finish line to a well deserved beverage.
