In 1984, the horse began competing in show jumping events, touching off what would become a long and successful career. Millar rode Big Ben to more than 40 Grand Prix titles including six Spruce Meadows Derbys, as well as taking the world cup show jumping championship two years in a row - the first World Cup Final coming at Gothenburg, Sweden in 1988, and then again the next year in Tampa, Florida. In 1989 he won the Grand Prix of Bordeaux, France and the Grand Prix of Stuttgart, Germany, ranking Millar number one in the world. Millar and Big Ben also won the du Maurier International twice, in 1987 and 1991, the world's richest grand prix event at that time.
