Horses and riders complete the competition over 3 days, each day consisting of a different discipline or phase. Horses and riders must complete a dressage test demonstrating obedience, discipline, accuracy and elegance. Then, they must complete a course of show-jumps designed to test their agility and accuracy at speed.
Finally, they need to be fit and athletic to complete a cross country ride jumping natural obstacles within a set time. The Ground Jury has ultimate responsibility for judging all three phases of the competition.
The Veterinary Delegate is responsible for ensuring that FEI regulations are adhered to and that horses are fit and able to complete all phases of the competition.
