The Hampton Court Stakes, a Group 3 race over 1 mile 2 furlongs, has been run under different titles for some considerable time, starting out as the ungraded Churchill Stakes, over 1 mile 4 furlongs, on the Saturday of the Ascot Heath fixture. Historically, the Churchill Stakes began as a 2 mile race in 1922 before being reduced to a mile and a half in 1950. The race was given Listed status in 1999 when it had a name change to the New Stakes, confusingly a former name of the Norfolk Stakes, and the distance was reduced to 1 mile 2 furlongs a year later in 2000. The race was then switched to the third day of the Royal meeting in 2002, when the meeting was extended to five days to commemorate the Golden Jubilee of Elizabeth II, that year running as the New Stakes, but for the Royal meeting it was renamed the Hampton Court Stakes. The extension of Royal Ascot was initially intended to be for one year only, but the extra day was such a success that it was retained thereafter. The race is now regularly titled the Hampton Court Stakes, named after the Tudor Royal residence of Hampton Court, although the race was promoted to Group 3 level and renamed the Tercentenary Stakes in 2011. Its new title was introduced to mark the 300th anniversary of Ascot Racecourse, which staged its first race meeting in 1711, but in 2017 the race reverted to its previous name, the Hampton Court Stakes.
Early history:- On Tuesday 17th June 1919 the Churchill Stakes was contsted for the first time, although it resulted in a walk-over for Lord Glanely's HE. On Thursday 15th June 1922 the Churchill Stakes for 4-year-olds over 2 miles was won by The Winter King, owned by Lord Rosebery and ridden by Charlie Elliott, who defeated Glorioso and Arquebus by a head and a distance. On Saturday 17th June 1950 Ascot was extended to a fifth day for the first time in its history, and the feature of that Ascot Heath card was the Churchill Stakes over a mile and a half which was won by the Harry Wragg trained Jai Mahal (7/2 jt fav) who beat Royal Drake (10/1) and Solar (100/7) by a neck and 3 lengths.
