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.

Sir Henry Richard Amherst Cecil was a British flat racing horse trainer. Cecil was very successful, becoming Champion Trainer ten times and training 25 domestic Classic winners. These comprised four winners of the Derby, eight winners of the Oaks, six winners of the 1,000 Guineas, three of the 2,000 Guineas and four winners of the St Leger Stakes. His 1000 Guineas and Oaks successes made him particularly renowned for his success with fillies. He was noted for his mastery at Royal Ascot, where he trained 75 winners.
