The story of Subzero, one of the most popular horses in Australian history. This is more than a racing story. Sure, there is the breeder who took a punt on an untried stallion, the owners who thought they were buying a fast two-year-old, the trainer who was breaking records and the jockey whose career was resurrected by the promise of a young grey stayer. However, his Melbourne Cup victory became secondary after he formed an endearing partnership with veteran clerk of the course Graham Salisbury. Subzero was reinvented under Graham's care, leading the horse to become a versatile community ambassador, and ultimately to his induction into the Australian Racing Hall of Fame. He has attended primary schools, visited children in hospital beds, socialised in aged-care facilities and even shared drinks with publicans in licensed establishments. He has become a celebrity in his own right, mixing with world leaders, pop stars and actors. This is also a story of the love that a man has for his best friend, who happens to have four legs and a tail, and answers to the name Subbie. Subzero's name was etched into history as a sporting champion, but his achievements off the racecourse are what make him legendary. Subzero is truly more than a Melbourne Cup hero.
