If you must ride through loose horses, keep your speed to a minimum and don't try to outrun them. If you have to catch a horse that has gotten away from its rider or catch your own horse that has broken loose from you, don't chase after the horse. Chasing only makes loose horses run faster. Talk soothingly and walk toward the horse. The loose horse may also be lured in with another horse.
Emergency Dismounting Safe equitation includes learning to make emergency dismounts.
This requires a great deal of practice and should begin in a riding ring at the walk, then at the trot, and eventually at the canter. Use a quiet, well-trained horse for practice. As you ride, kick both feet out of the stirrups and drop your hands to the withers, but maintain contact with the reins. Aided by the natural rhythm of the horse's movement, push away with your hands, swinging your right leg back over the croup and bringing both legs forward quickly and as close together as possible. Maintain your balance by holding onto the front of the saddle or the horse's mane.
