Thoroughbred racing career
Tabor was the owner of a successful chain of English betting shops and used his wealth to enter the sport of Thoroughbred horse racing. He sold his betting shop business for about $50-million in 2003 by which time he had already won the Kentucky Derby and Belmont Stakes representing two-thirds of the American Triple Crown with Eclipse Award winner Thunder Gulch.
English-born Tabor, who is currently a resident of Monaco, has campaigned many of his runners in partnership with Susan Magnier, wife of Coolmore Stud owner John Magnier. His runners have performed in top company on both sides of the Atlantic in recent years. Tabor won his first major British race with Entrepreneur (owned with Mrs. Sue Magnier), taking the 1997 2,000 Guineas at Newmarket, England. They owned 2001 and 2002 Epsom Derby winners Galileo and High Chaparral, the latter also capturing the Irish Derby and the Breeders' Cup Turf. On July 29, he and his partners won the 2009 Sussex Stakes with Rip Van Winkle, a colt by Galileo (horse) out of Looking Back.
Michael Tabor is one of only four men to have raced both a Kentucky Derby winner (Thunder Gulch) and an Epsom Derby winner (Galileo) and High Chaparral. The others are Paul Mellon, John W. Galbreath and Prince Ahmed bin Salman.
His horse Hurricane Run was voted the World's Top Ranked Horse for 2005 by the International Federation of Horseracing Authorities (IFHA).
He is a fan of West Ham United a club he tried, but failed, to buy in the 1990s.
In the 2008 issue of The Sunday Times Rich List, Tabor was rated the 121th Richest Man in Britain with a fortune of more than $1.24 billion.
His son Ashley Tabor is currently Chief Executive of Global Radio, the radio company that bought GCap Media in 2008 with money from his father and his fathers friends (listed above) and two banks. In 2009 the company posted overdue accounts and later was forced to write off £193m of the investment in the business and seek further investment from shareholders, despite publicly stating earlier in the year that shareholders would not be forced to put in more funds.
