Who trained Arkle?

For the uninitiated, Arkle was arguably the greatest steeplechaser of all time. In a four-year period between 1962 and 1966, Arkle won 22 of his 26 races over fences – including the Cheltenham Gold Cup three years running in 1964, 1965 and 1966 – and finished behind just six horses. His Timeform Annual Rating, of 212, is the highest ever awarded to a steeplechaser and 20lb superior to any other steeplechaser in history, with the exception of his stable companion, Flyingbolt. Arkle was owned by Anne Grosvenor, Duchess of Westminster, and trained by Thomas William ‘Tom’ Dreaper at the family farm in Greenogue, Kilsallaghan, Co. Dublin, Ireland.
