Endurance riding is a long-distance equestrian sport where horse and rider work together to complete a set course, often ranging from 25 to 100 miles. The event tests the stamina and fitness of both the horse and rider, with checkpoints along the route to monitor the horse's health and recovery. Competitions are typically held in natural terrains, such as forests or mountains, and can last several hours to a full day. Riders must be knowledgeable about horse care, navigation, and pacing to successfully complete the ride while ensuring the well-being of their horse, often referred to as the equine partner.
