What Is the Reining Phase?
The reining phase of the NRCHA World's Greatest Horseman is the first dimension of the three-phase competition, and it establishes the foundation of the complete reined cow horse. In reining, horse and rider execute a prescribed pattern of maneuvers demonstrating the horse's responsiveness, athleticism, and willingness — all performed in a large arena at controlled speed.
Reining patterns include large fast circles and small slow circles, flying lead changes, rollbacks over the hindquarters, spinning turns (360-degree spins in place), and the signature sliding stop — where the horse gallops at speed and then locks its hindquarters and slides to a controlled stop, often for distances of 20 to 40 feet or more.
The sliding stop is reining's most iconic maneuver — a horse galloping at full speed that locks its hindquarters and slides across the arena in a controlled, dramatic halt. In competition it is judged on both distance and control.
Scoring the Reining Phase
Reining is scored by judges on a scale that begins at 70 points, with each maneuver receiving a modifier from -1.5 (extremely poor) to +1.5 (excellent). Penalties are assessed for errors such as stepping out of a lead change, incorrect pattern execution, or loss of control. The judge's score reflects the overall impression of control, athleticism, and smoothness — a winning reining run looks effortless even as it demands extraordinary athletic effort from the horse.
In the WGH format, the reining score contributes to the cumulative score that ultimately determines the champion — making a strong reining run essential but not sufficient. A rider who dominates in reining but struggles in cow work will not win the WGH title.
