Canadian International Stakes
On his first start as a four-year-old, Brian Boru won the Listed Alleged Stakes at Leopardstown, beating Napper Tandy by three quarters of a length. The rest of Brian Boru's season was disappointing as he failed to win in eight subsequent races. His best efforts came when finishing second in the Irish St. Leger (to Vinnie Roe) and the Prix Kergorlay and third (to Sulamani) in the Canadian International Stakes.
