Eventing is an equestrian event where a single horse and rider combine and compete against other competitors across the three disciplines of dressage, cross-country, and show jumping. This event has its roots in a comprehensive cavalry test that required mastery of several types of riding. The competition may be run as a one-day event (ODE), where all three events are completed in one day or a three-day event (3DE), which is more commonly now run over four days, with dressage on the first two days, followed by cross-country the next day and then show jumping in reverse order on the final day. Eventing was previously known as Combined Training, and the name persists in many smaller organizations. The term "Combined Training" is sometimes confused with the term "Combined Test", which refers to a combination of just two of the phases, most commonly dressage and show jumping.
Equestrian at the 1980 Summer Olympics was represented by six events. All of them, with the exception of the Individual Jumping Grand Prix, were held in the Trade Unions' Equestrian Complex, which is situated in the Bitsa Forest Park. Individual Jumping Grand Prix was held in the Grand Arena of the Central Lenin Stadium at Luzhniki.
Equestrian competitions at the 1968 Summer Olympics in Mexico City, Mexico featured team and individual competitions in show jumping, eventing, and dressage. Mexico City proved a challenging site since it was 2,300 meters above sea level, resulting in 30% less oxygen in the air. The horses at the 1955 Pan American Games, which was also held in Mexico City, arrived a few weeks before the Games to adjust, but had difficulty in the competition. However, racehorses that competed at the same location and who were shipped in the day before, and left the day after the race, performed fine. It was discovered that although horses would adjust immediately to the high altitude during the first few days after arrival, they showed weakness and decreased performance around Day 10, which continued to Day 20. Therefore, nations were advised to ship in horses 3–4 weeks before the competition, which would allow them time to recover from the long travel, as well as adjust to the difference in altitude. Argentina, Ireland, and the USSR were the first to ship horses over, who arrived mid-September. France and Germany were the last countries to send their horses, who arrived 28 September 20 days before the competition was to start.
