Endurance riding is a long-distance equestrian sport where horse and rider compete to complete a set course within a specific time frame. Races can range from 25 to 100 miles, often taking place over varied terrain. The focus is on the horse's stamina, health, and ability to navigate challenges, making it a test of both endurance and horsemanship. Competitions are typically divided into different classes based on distance and difficulty. Riders must monitor their horse's condition closely, ensuring it remains fit and healthy throughout the event. Successful completion often requires training, strategy, and a strong bond between the horse and rider, emphasizing the importance of teamwork in the sport.
