About Queen Elizabeth II
Queen Elizabeth II is the leading patron and most readily associated face of British racing which along with breeding thoroughbred racehorses at her Royal Stud, part of her Sandringham estate, is her true sporting passion and arguably the one environment in which she allows herself to be (almost) one of the crowd.
The Queen’s love affair with the ‘Sport of Kings’ began when she was a young girl, a passion encouraged by her mother who was a notable jumps racing owner and who herself enjoyed considerable success. The Queen however has always preferred Flat racing, and over the years her purple and gold racing colours with red sleeves and black cap have been carried to a number of famous successes.
Champion owner in both 1954 and 1957, archivists suggest that The Queen has owned more than 1600 winners during her career, many of which she has bred herself having been closely involved in studying the bloodlines and planning the matings of her broodmares to blue-blooded stallions . Amongst her biggest success have been winning four of the five British classics, the most recent being Dunfermline, who won both the Oaks and St Leger in 1977.
The one classic to elude The Queen is the Epsom Derby, a race in which her great horse Aureole finished runner-up in 1953, whilst in 2012 the racing world was in fevered anticipation of the monarch finally winning the most prestigious three-year-old colts race in the world when her Dante Stakes winner Carlton House, ridden by Ryan Moore, was sent off favorite for the mile-and-a-half Epsom race in front of more than 250,000 race fans at the track and tens of millions more watching the race worldwide.
After travelling well through the race the royal horse came to challenge inside the final furlong but lost a shoe and became unbalanced, failing to quicken and finishing a close third behind the turbo-charged finish of French star Pour Moi.
The Queen did however achieve one life’s ambition at Royal Ascot 2013, the meeting which she attends every year in mid-June for five successive days and which is brimming over with pomp and pageantry. Her home-bred filly, Estimate, trained by Sir Michael Stoute and ridden by Ryan Moore, put up the performance of its life to win the showpiece race of the fixture, the Group 1 Ascot Gold Cup. Staying-on bravely at the end of the 4000m contest, the Queen’s filly beat Ireland’s Simenon by a neck and returned to a rapturous reception from the 70,000 crowd who overwhelmed the viewing area of the winners’ enclosure.
Normally placid and rarely showing much emotion, the video of The Queen watching the closing stages of the Gold Cup went viral as she ended up breathless with delight as her horse won in a photo-finish, showing just how much racing and breeding horses means to the 88-year-old monarch.
Many of the Queen’s horses are trained by Sir Michael Stoute at Newmarket, but she also has horses in training with Richard Hannon, Roger Charlton, Michael Bell, and Andrew Balding, whilst in recent years she has campaigned a few horses over jumps and has them stabled with Nicky Henderson.
