What is Wyoming Mustang Days?

Wyoming Mustang Days is an open horse show explicitly for branded BLM wild horses and burros to compete in a fun yet challenging environment. The show has grown over the years and draws competitors from all over Wyoming, Montana, the Dakotas, Colorado, Utah, Idaho and beyond!

What You Need to Know

This year, Wyoming Mustang Days will utilize the Sweetwater Events Complex in Rock Springs, WY for the show. Any stalling or overnight camping needs are arranged directly through the Sweetwater Events Complex- not the Wyoming Mustang Association. Your horse will need a current negative Coggins, health certificate and brand card to enter the fairgrounds and/or rent a stall. You can purchase shavings from the fairgrounds staff or bring your own. Hay will need to be brought with you or purchased locally. Please contact Shae Lux at the Sweetwater Events Complex to reserve your stalls ($20 per night) or RV spots ($30+tax per night) 307-389-5618


Wyoming Mustang Days hosts several divisions based on rider age, horse ability and the rider's status. Please note that if you enter the Green Horse division, you may not cross enter that horse in any additional divisions. The same is true for Leadline riders.
