The Equestrian Events at the 1976 Summer Olympics in Montreal included Show Jumping, Dressage and Eventing. All three disciplines, except for the Nations Cup, were held at the equestrian stadium in Bromont, which had a capacity of 15,000 spectators, and the cross-country and steeplechase were also nearby. Building this stadium provided some headache for the Organizing Committee after the original estimate of 1 million Canadian dollars increased to CAD 4,425.
Poland and Chile were not allowed to ship horses into the host country due to the concern of Piroplasmosis, and France and Italy also had to keep some horses home due to veterinary regulations. Overall 23 nations competed: Argentina, Australia, Austria, Belgium, Bolivia, Canada, Denmark, France, Federal Republic of Germany (FRG), Great Britain, Guatemala, Ireland, Italy, Japan, Mexico, Netherlands, Puerto Rico, the Soviet Union, Spain, Sweden, Switzerland, Uruguay, and the USA, with the Montreal Games being the first for Guatemala and Puerto Rico in equestrian events.
The 1976 Olympics was also the first Games with a disqualification due to a positive equine drug test, after San Carlos, ridden by Ronald McMahon of Ireland, received treatment following an injury during transport. Although the treatment was needed, the rules did not allow for him to compete.
Tom Gayford, assisted by Robert Jolicoeur, built the massive courses ridden by 61 riders from 20 countries. All courses were to be ridden at 400 m/min, and had 15 obstacles with 18 jumping efforts, including a 5m water. Round A, 950 meters in length, had verticals up to 1.60 meters and a 2.20 meter wide oxer with a 1.55 meter front rail and a back rail at 1.60 meters. Round B (660 meters) had a narrow 1.70 meter vertical, and the oxers were also raised in height. The final jump off was 470 meters long. Only 39-year-old Alwin Schockemöhle was able to pull off two clear rounds to win gold. The next three highest placed riders had 12 penalties apiece, and they had to jump off for silver and bronze.
The Nations Cup was held in the Olympic Stadium in front of 55,000 spectators, despite a great debate to move it to Bromont after intense rain. However, course dimensions were reduced. Alwin Schockemöhle managed to complete the 2 Nations Cup courses with 4 and 8 penalties respectively, helping Germany finish with team silver.
