Bull rider Mason Lowe's death after he was thrown from and then stomped by a bull Tuesday night at the National Western Stock Show was shocking.

It hit even harder for the men who know what stepping into that arena entails, including retired champion bull rider Kody Lostroh​, of Ault, located in northeast Colorado.

"I don’t know how to describe a guy’s thoughts when a fellow teammate essentially is killed doing something like this. It’s indescribable really," Lostroh​ said.

Lostroh won the Professional Bull Riders World Championship in 2009. He recently retired from bull riding.

The risks taken in the sport may seem outrageous to outsiders, he said. But Lostroh​ said all riders are "willing to pay the ultimate price.

"I think that’s something that’s hard for people that haven't done it to understand, but as a bull rider, you can respect that he was willing to pay that price," Lostroh​ said. "And unfortunately he did." Photo: Courtesy Professional Bull Riders

Bull riders started donning the protective vests Lowe was wearing at the time of his death about 20 years ago. They help distribute the weight of a bull's impact and slip the animal's hooves off the vital area.

But Lowe was laying in such a position when the bull struck him, no vest could've helped.

"It’s bad luck essentially if you’re laying flat and the bull hits you square," Lostroh​ said.

Lostroh​ doesn't believe bull riding has gotten much more or less dangerous in recent years. More riders wear protective helmets now, which reduce concussions and protect from other injuries. But at the same, Lostroh said, modern bull breeding programs are putting our heavier, stronger animals.

"The fact is: It’s always been a dangerous sport and it’s always going to be a dangerous sport," he said.
