The ride is divided into sections, with different names (legs, phases, loops etc.), depending on sanctioning organization. After each section, horses are stopped for a veterinary inspection (usually called a "vet check" and less often called a "vetgate"), where they are checked for soundness and dehydration, with their pulse and respiration taken. To continue the ride, the horse must pass the examination, including reducing its heart rate below that specified for the event, typically 64 bpm, although terrain and weather may require the ride veterinarians to set a different maximum target. The riders' time keeps running until their horses reach the required target, so it is important that the horses recover as soon as possible. Any horse deemed unfit to continue (due to lameness or excessive fatigue, for example) is eliminated from further competition (this is called being "pulled").
