Nathaniel is an Irish-bred British-trained Thoroughbred racehorse. Nathaniel failed to win in two races as a two-year-old but attracted attention by running Frankel to half a length at Newmarket. At three he recorded his first major win in the King Edward VII Stakes at Royal Ascot and then won Britain's most prestigious all-aged race, the King George VI and Queen Elizabeth Stakes over the same course and distance. Nathaniel returned in 2012 to win the Eclipse Stakes on his seasonal debut. Although he failed to win again he was placed in the King George, the Irish Champion Stakes and the Champion Stakes before being retired at the end of the year. During his racing career he earned £1,464,688. He made an immediate impact as a breeding stallion, siring the champion filly Enable in his first season at stud.

Frankel is a retired champion British Thoroughbred racehorse and current sire. He was unbeaten in his fourteen-race career and was the highest-rated racehorse in the world from May 2011. He was trained by Henry Cecil in Newmarket and ridden in all his races by Tom Queally.
