Competition format
Show jumping
Five rounds are ridden to determine individual medals. Riders placing first through 60th advance to the second round. The top 45 riders of round 2, including ties for 45th, advance to the third round. The top 35 riders of the third round progress to the 4th round, but only up to three riders per team. In the fourth round, the slate is wiped clean and all riders begin with zero faults. The top 20 riders in round 4 advance to round 5, and ride another course. The faults for individual final round A and B and added together to determine individual medals. The team competition completes three rounds to determine medals. It runs concurrently with the individual competition so team riders are also competing for individual medals. The first round for team competition is the round 2 course for individual medals. The top eight teams from the first team round advance to the second team round. The scores for these eight countries over team rounds 1 and 2 are combined, and medals are awarded based on those scores.
Dressage
Teams are made up of three riders, all of whom are also competing concurrently for individual medals. Additionally, countries who can not make a full team may send riders to compete for individual medals. All riders compete in the Grand Prix, which serves as the first round of both the individual and team medals. The top seven teams advance to the Grand Prix Special, which is a slightly more rigorous test. The combined scores for those teams in both the Grand Prix and the Special determine the team medals, with the team with the highest score winning gold. Riders completing the Grand Prix test may move on to the Grand Prix Special if their team is in the top seven. Additionally, the top 11 riders who do not qualify with a team may also advance to the Special to ride for individual medals. The top 18 riders from the Special move on to the third individual round, the freestyle. Each rider designs their own test for the freestyle, which must be set to music and has several compulsory movements. Riders can tailor a test to their horses' strengths, as well as incorporate movements that are more difficult than those required in the Grand Prix or the Special in order to increase their scores. Individual medals are assigned based on scores in the freestyle.
Eventing
Competitions for team and individual medals ran concurrently. Riders performed a dressage test, a cross-country round, and a jumping round. Team medals were then awarded by adding together the best three scores from a country's team, out of a maximum of five team members, from all three phases, the team with the lowest number of penalty points winning the gold. The top 25 individual scores after the first show jumping round performed a second, final, show jumping round to determine individual medals, with up to 3 riders in the individual running per team. Therefore, those competing for individual spots completed one dressage test and cross-country round, and two jumping rounds.
