Each competitor climbs onto a horse, which is held in a small pipe enclosure called a bucking chute. When the rider is ready, the gate of the bucking chute is opened and the horse bursts out and begins to buck. The rider attempts to stay on the horse for 8 seconds without touching the horse with his free hand. On the first jump out of the chute, the rider must "mark the horse out." This means he must have the heels of his boots in contact with the horse above the point of the shoulders before the horse's front legs hit the ground. The rider that manages to complete a ride is scored on a scale of 0-50 and the horse is also scored on a scale of 0-50. Scores in the 80s are very good, and in the 90s, are exceptional. A horse who bucks in a spectacular and effective manner will score more points than a horse who bucks in a straight line with no significant changes of direction.
[edit] Saddle vs. bareback bronc riding
Bareback Bronc riding
Saddle Bronc ridingSaddle bronc and bareback bronc styles are very different. In saddle bronc the rider uses a specialized saddle with free swinging stirrups and no horn. The saddle bronc rider grips a simple rein braided from cotton or polyester and attached to a leather halter worn by the horse. The rider lifts on the rein and attempts to find a rhythm with the animal by spurring forwards and backwards with his feet.
The bareback bronc rider does not use a saddle or rein, but uses one hand to grip a simple handle on a surcingle style rigging placed on the horse just at the horse's withers. The rider leans back against the bucking horse and spurs up and down motion with his legs, again in rhythm with the motion of the horse.
[edit] The horse
The bucking horse is usually a gelding, a castrated male horse. Because bucking horses usually travel in close quarters and are housed in a herd setting, geldings are generally less disruptive and more prone to get along with one another. However, mares are also used, and while a mixed herd of mares and geldings is a bit more prone to disruptions, they can be kept together without great difficulties. Stallions are less common, because they can be disruptive in a herd and may fight if there are mares present.
The modern bronc is not a truly feral horse. Most bucking stock is specifically bred for use in rodeos, with horses having exceptional bucking ability fetching a high price. Most are allowed to grow up in a natural, semi-wild condition on the open range, but also have to be gentled and tamed in order to be managed from the ground, safely loaded into trailers, vaccinated and wormed, and to load in and out of bucking chutes. The also are initially introduced to bucking work with cloth dummies attached to the saddle. Due to the rigors of travel and the short bursts of high intensity work required, most horses in a bucking string are at least 6 or 7 years old.[1]
