Equestrian has strong claims to be the most unique of Olympic sports. It is the only one to revolve around animals, and the only event in which men and women compete entirely on equal terms.
Michael Tucker, BBC Sport
"All three disciplines require different skills. The eventing is like motor cross or rallying, the dressage requires the most detailed team-work between horse and rider and show jumping requires jumps over very big fences where the attention to detail is really shown to its ultimate. Watch out for Charlotte Dujardin, who is a very young talent in the dressage. William Fox-Pitt has been world number one before but will be looking to win his first major title at London 2012. Germany's Michael Jung is the reigning world and European champion in the eventing and is the hot favourite to land the Olympic title."
It is also one of the most varied and enthralling of sports - from the discipline of dressage to the danger of eventing to the drama of jumping, equestrian is an entertaining and exciting spectacle.
The equestrian events at the 2008 Olympics were somewhat sidelined by the fact that they were held in Hong Kong, 1,200 miles away from host city Beijing.
In London, by contrast, the sport will be right at the heart of things, with the events being held in Greenwich Park.
Great Britain have a rich equestrian history yet have won just one Olympic gold since 1972 - and even that came in controversial circumstances, when Leslie Law and Shear L'Eau were promoted to the top of the podium in 2004 after the original winner was disqualified for a rules infringement.
Why is it good for you?
An hour's riding burns about 120 calories at walking pace, 360 calories at trotting pace and 480 at galloping pace. Although it may seem that the horse is receiving all the exercise, this equates to the calories lost in a 30-minute jog or cycle ride carried out at a similar speed.
The position taken when riding a horse works muscles in the dorsal and abdominal region that are seldom used in everyday life. It provides steady exercise without straining the knee and ankle joints.
Horse riding is further recognised as possessing excellent therapeutic and stress relieving qualities due to the relationship developed between rider and horse.
Equestrian sports are enjoyed by people of all ages, as shown by German rider Reiner Klimke who won six Olympic gold medals between 1964 and 1988.

A total of 200 athletes, spread across all three disciplines, will compete at Greenwich Park.
Equestrian consists of three disciplines - dressage, eventing and jumping.
The dressage competition will run from Thursday 2 August to Thursday 9 August, the eventing competition will run from Saturday 28 July to Tuesday 31 July, and the jumping competition will run from Saturday 4 to Wednesday 8 August.
All three have a team event and an individual event for men and women.
tests are performed in a sand arena of 60m x 20m, with seven judges awarding points for the harmony, lightness and free-flowing movement of the horse at all paces. A dressage team comprises of three athletes and three horses.
The individual and team events occur at the same time, with a rider's score relevant to both. After the first phase, the Grand Prix, the best seven teams (including those tied for seventh) and best 11 individuals (including those tied for 11th) who have not already qualified in the team event, qualify for the Grand Prix Special.

is divided into three disciplines - dressage, cross-country and jumping - with penalty points accumulated throughout and the lowest score winning.
The eventing competition takes place over four days, with riders competing for both the individual and team medals. The first jumping test on the final day determines the placings in the team event, with a second jumping test which comprises the best 25 riders (and any tied for 25th place) then determining the final standings in the individual event.
takes place around a short course containing 12-14 fences. There are five rounds of competition, two of which determine the placings in the team event, while all five contribute to the the individual event score.
Riders are timed on the course and penalised for any jumps they fail to clear correctly. The rider that finishes with the fewest penalties in the quickest time wins the gold.
Britain have never won an Olympic dressage medal but that should change this summer. Team GB are the reigning European champions, with the experienced
and talented young riders
more than capable of competing with the best.
Great Olympic moment
The 1960 team eventing gold was won by Australia after Bill Roycroft insisted on leaving his hospital bed to compete in the jumping test. He had suffered concussion and a broken collarbone after falling during the endurance event.
