Kempton Park Racecourse is a horse racing track together with a licensed entertainment and conference venue in Sunbury-on-Thames, Surrey, England, near the border with Greater London; it is 16 miles south-west of Charing Cross in central London. The site has of flat grassland surrounded by woodland with two lakes in its centre. Its entrance borders Kempton Park railway station which was created for racegoers on a branch line from London Waterloo, via Clapham Junction. It has adjoining inner and outer courses for flat and National Hunt racing. Among its races, the King George VI Chase takes place on Boxing Day, a Grade 1 National Hunt chase which is open to horses aged four years or older. History The racecourse was the idea of 19th-century businessman and Conservative Party agent S. H. Hyde, who was enjoying a carriage drive in the country with his wife in June 1870 when he came across Kempton Manor and Park for sale. Hyde leased the grounds as tenant in 1872 and six years later in July 1878 Kempton opened as a racecourse. This was the feudal lord's demesne of a manor recorded in the Domesday Book and has had at least four variant names; though early Victorian gateposts exist, no buildings of the manor house remain. For many years Kempton's Easter meeting (Saturday and Monday) was one of its highlights of the year, with the Roseberry Stakes (over the 1m 2f of the Jubilee course) and the 2,000 Guineas Trial on the first day, followed by the Queen's Prize over 2m, plus the 1,000 Guineas Trial on the Monday. The site briefly closed (2 May 2005 – 25 March 2006) to reopen with a new all-weather polytrack (synthetic material) main track and floodlighting to enable racing at all light levels and in all but the most severe bad weather. Flat racing since 2006 has been run on the synthetic track, so the historic "Jubilee Course", a mile-long spur that joined the main track by the home bend, used for the "Jubilee Handicap" which parred the Cambridgeshire and the Stewards' Cup in seniority, was abandoned. It is now overgrown for racing; however, it joins the outskirts of the park as part of the green belt. The old flat course comprised: a right-handed triangular course of about 1m 5f; a straight six-furlong course that intersected the back straight of the triangular course; and the 1m 2f Jubilee
