Ballydoyle is the Mecca of thoroughbred horse training. Under the mastership of Aidan O'Brien, who at the age of forty has already been Champion Trainer four times in Britain and fifteen years in a row in Ireland, Ballydoyle has been the cradle of legendary horses like Yeats, Galileo, High Chaparral, George Washington, Dylan Thomas, Rock of Gibraltar and Duke of Marmalade. Now, for the first time, through the lens of Anne-Marie O'Brien - Aidan O'Brien's wife and herself a former Champion National Hunt Trainer - and the pen of acclaimed sportswriter David Walsh, you are being given a glimpse behind the scenes at Ballydoyle.
