Bred and raised by the 26-time World Champion and "King of the Cowboys," Trevor Brazile, Relentless Glory is one of the premier rope horse mares in the industry. She won more than $48,000 according to Equi-Stat, though her true earnings on both the head and heel side exceed that figure significantly. Her presence is undeniable in the arena, and she's good-minded enough that Trevor's teenage son, Treston Brazile, roped on her in the non-pro and jackpots as well. Brazile describes her as "showy and forgiving" and "good on both ends."

Relentless Glory is by the leading $87-million-sire, Metallic Cat. Her dam, Z Oh Six, is a full sister to many winners, including Trevor’s great calf horse Deputy—who he rode at the National Finals Rodeo for nearly a decade. She is a full sibling to Relentless Big Shot, who won over $588,000 between the futurities and the 2023 World Series finale.

This mare's future as a producer is already proving to be extraordinary. Relentless Empire, out of Relentless Glory, sold for $900,000 to top the 2026 Old West Rope Horse Sale.
