The equestrian disciplines are unique among Olympic sports in the sense that men and women compete on the same terms both horse and rider are declared Olympic medal winners.
Eventing is a combination of dressage, jumping and cross-country tests which are carried out over four consecutive days. The aim of the rider is to achieve the lowest number of penalties in all three disciplines.
Team GB have won a total of 20 Olympic eventing medals, including silver in the team event at London 2012. The last gold medal was won by Leslie Law in the individual event at Athens 2004.
