Octagonal (8 October 1992 – 15 October 2016) was a champion New Zealand-bred, Australian raced Thoroughbred racehorse, also known as 'The Big O' or 'Occy'. He was by the champion sire Zabeel, out of the champion broodmare Eight Carat, who also produced Group One winners Mouawad, Kaapstad, Diamond Lover and (Our) Marquise. Biography Bob Ingham, along with brother Jack Ingham, purchased and raced Octagonal. Trained by John Hawkes, Octagonal made his debut late in 1994, and was crowned the Australian Champion Two Year Old on the strength of his autumn campaign, which comprised wins in the Todman Trial and AJC Sires Produce Stakes and close seconds in the STC Golden Slipper and AJC Champagne Stakes. As a three-year-old, Octagonal won seven of his eleven starts, and took his record to 10 wins from 16 starts. In addition to beating a high-standard crop in Sydney's three-year-old autumn triple crown - the Canterbury and Rosehill Guineas and the Australian Derby - Octagonal won the two richest weight-for-age races on the Australian calendar, the W. S. Cox Plate and the Mercedes Classic. With earnings of just short of A$4 million, Octagonal was voted the 1996 Australian Champion Three Year Old, Australian Horse of the Year, and remains the last horse to have won the triple crown. The Victoria (spring) and Australian Derby (autumn) double eluded him, however, as he was narrowly defeated by Nothin' Leica Dane in the Victoria Derby. Octagonal returned to the track as a four-year-old, but his win the Underwood Stakes was the only highlight of a spring campaign that saw him unplaced in six of his seven starts. Meanwhile, the horses who had finished second to him in the triple crown - Saintly and Filante - won three races each, including the Epsom Handicap, the W. S. Cox Plate (where they were first and second), and the Melbourne Cup. Octagonal's final campaign, during the autumn, was more consistent, and featured Group One wins in consecutive starts in the Chipping Norton Stakes, Australian Cup, and the Mercedes Classic. At his final start, he was runner-up in the AJC Queen Elizabeth Stakes; a feat coincidentally emulated in the farewell of his champion son, Lonhro, seven years later. Octagonal retired to stud after 28 starts with a record of 14 wins (10 Group 1), 7 seconds (6 in GI or GII races) and a third. He ended his racing career with a
