Mounted games is a branch of equestrian sport in which very fast games are played by people of all ages on ponies up to a height of 15 hands (60 inches, 152 cm).
They require a high degree of athletic ability, good riding skills, hand-to-eye coordination, determination, perseverance, and a competitive spirit, which nevertheless requires an ability to work together with other riders and a willingness to help one another.
Mounted Games were the inspiration of Prince Philip. When Col. Sir Mike Ansell was Director of the Horse of the Year Show, Prince Philip asked if he could devise a competition for children who could not afford an expensive, well-bred pony, and in 1957 the Horse of the Year Show, then at Harringay Arena in North London, England, staged the first Mounted Games Championship for the Prince Philip Cup—it was an immediate box office success.
The sport of mounted games as it exists today was founded by Norman Patrick. His aim was to extend the sport, previously age-restricted by Pony Club, for wider participation, and for this reason, in 1984, he established the Mounted Games Association of Great Britain. In the years which followed his continued support and patronage ensured that the sport spread across Great Britain and beyond. At the time of Patrick's death in 2001, the sport which he had established was being enjoyed by many riders across the world, and the
International Mounted Games Association, which was formed in 2003, now has members in twenty countries on four continents.
