They call him Flash.
Built the old way—outside, horseback, every day.
Pepinstep is a powerful, keen-minded stallion with deep cow horse roots and proven ability in and out of the arena. Bred by the respected Flag Ranch and started by elite cow horse trainer Matt Koch, he carries both the physical tools and the mental edge to pass on to the next generation of great horses.
Koch picked him up as a yearling from the NRCHA Snaffle Bit Futurity Sale and developed him from the ground up—branding, riding outside, and putting him to work with the kind of everyday cowboying that builds real-world, reliable horses.
Calm mind. Athletic build. Natural cow sense.
Flash stood out early for the traits that can't be trained into a horse—a level head, an athletic frame, and instincts straight from the best cow horse blood in the book. Those traits pointed him straight toward the roping pen.
Enter World Champion Colby Lovell, who took him to the rope horse futurities to make him his next great rope horse stallion.
A commanding win at the Riata.
Flash made his mark at the 2023 Riata Championships, where Colby Lovell rode him to an emotional and commanding win in the #14.5 Championships—solidifying his place as one of the most exciting young rope horse stallions in the game.
Now standing for Theorem Ranch, Flash brings more than genetics to the table: a proven record, a willing heart, and the versatility that builds champions. With his size, structure, mind and grit, he's built to sire horses that go to work, stay level-headed, and win.
