Ajax was a champion Australian bred Thoroughbred racehorse and sire, who won 18 consecutive races before he was defeated at the odds of 40/1 on, causing a huge racing sensation. He had wins from 5 furlongs (1,000 metres) to 1½ miles (2,400 metres), equalled the Australasian record for a mile (1,600 metres), and created three new race records. At stud in Australia, Ajax proved to be a good sire. He was then sold as a 14-year-old horse and exported to the United States before he was later sold to Bing Crosby and Lin Howard. Ajax was inducted into the Australian Racing Hall of Fame in 2004.
