Caulfield Cup
As a three-year-old in 1906/07, Poseidon had 14 starts for 11 wins, including the Caulfield Cup (in race record time), Melbourne Cup, Victoria Derby and AJC Derby. In achieving this, Poseidon became the first horse to complete the Caulfield Cup-Melbourne Cup double. In winning the Caulfield Cup again the following year, he also became the first horse to win consecutive Caulfield Cups.
