Cross-country equestrianism is a discipline within the sport of eventing, where horse and rider navigate a challenging outdoor course that includes various natural obstacles such as logs, water elements, and ditches. The goal is to complete the course within a set time while jumping the obstacles in the correct order. Cross-country tests the horse and rider's stamina, courage, and ability to negotiate diverse terrain. It is one of the three phases in eventing, alongside dressage and show jumping.
