Earth Summit (1988–2005) was a British racehorse. He was foaled in 1988, a son of Celtic Cone, who was a winning stayer on the flat and over hurdles. Celtic Cone loved soft ground, as did many of his progeny. Earth Summit was bought by a six-man partnership aptly named The Summit Partnership, in 1992 (including footballer Ricky George, Aintree press officer Nigel Payne, Partner in an accountancy firm Peter Earl, retired businessman Gordon Perry, local government officer Mike Bailey and media buying agency proprietor Bob Sims) and began his racing career as a four-year-old, finishing second in a bumper (a National Hunt flat race) at Cheltenham.
