Who is, or was, the most successful trainer in the history of the Grand National?

In the history of the Grand National, the original ‘Master of Ballydoyle’, Vincent O’Brien, had the distinction of saddling three winners in a row, namely Early Mist, Royal Mist and Quare Times, in 1953, 1954 and 1955, respectively. However, three men have saddled four Grand National winners apiece and are, jointly, the most successful trainers in the history of the Grand National.

In the pioneering days of the Grand National, Epsom-based trainer George Dockeray was the first to achieve the feat when, in 1852, the unfancied 50/1 chance Miss Mowbray, ridden by Mr. Alec Goodman, beat Maurice Daley and Sir Peter Laurie by a length and half a length in the fourteenth renewal of the famous steeplechase. Dockeray had previously trained the winner of three of the first four ‘official runnings of the Grand National, namely Lottery (1839), Jerry (1840) and Gaylad (1842).

Over a century later, Fred Rimmell, a.k.a. ‘Mr. Grand National’, became the second trainer in history to saddle four Grand National winners when Rag Trade beat Red Rum by two lengths in the 1976 renewal. Rimmell, of course, was the trainer who had benefited from the dramatic collapse of Devon Loch in 1956, but aside from E.S.B., whose jockey Dave Dick admitted ‘was a terribly lucky winner’, also saddled Nicolaus Silver (1961) and Gay Trip (1970).

Last, but by no means least, Donald ‘Ginger’ McCain, trainer of Red Rum, who achieved legendary status by winning the Grand National in 1973, 1974 and 1977, finally achieved his fourth win, at the age of 73, in 2004. On that occasion, the twelve-year-old Amberleigh House, ridden by Graham Lee, defeated co-favourite Clan Royal by three lengths.

Is Aidan O’Brien related to Vincent O’Brien?

The simple answer is no, Aidan O’Brien is not related to the late Michael Vincent O’Brien, but the current ‘Master of Ballydoyle’ has much in common with his predecessor. Indeed, it was Vincent O’Brien who bought Ballydoyle House, in Co. Tipperary in 1951 and, later, along with his son-in-law, John Magnier, and the late Robert Sangster, established what became known as the Coolmore syndicate, for whom Aidan O’Brien has been private trainer since 1996.

Both Aidan and Vincent O’Brien began their training careers in National Hunt racing; both have the distinction of having won the Champion Hurdle at the Cheltenham Festival three years running, Aidan with Istabraq in 1998, 1999 and 2000 and Vincent with Hatton’s Grace in 1949, 1950 and 1951. Similarly, both men subsequently rose to become the dominant force in Flat racing, not just in Ireland, but in the whole of Europe and both became Champion Trainer in Britain, despite training on the other side of the Irish Sea.
