Such a stride is one thing that gives a horse class, says Ed Anthony, pedigree consultant for Three Chimneys Farm in Midway, Ky., whose job includes advising mare owners on the most suitable stallion crosses. Horses with it include AP Indy and Fusaichi Pegasus. They have a smooth, fluid stride that just gobbles up the ground. In other words, says Galley, it allows the horse to withstand the rigors of racing and ward off the fatigue factor. Such structural durability also means the horse is less likely to be injured and require lay-up or rehabilitation time, which would disrupt conditioning programs and interfere with consistent performance.
Strong hooves provide structural stability that contributes to gait efficiency.
They also minimize the development of hoof lameness that could interfere with performance. Horses that paddle or wing because they toe in or out are likely to incur interference injuries as their muscles fatigue over the miles. Excessive excursion of any limb will hasten the onset of fatigue. All of this, of course, can inhibit athletic ability and shorten a horse's competitive career. A strong back and loins give the horse the ability to strongly engage his haunches.
