Question: At which racecourse, known as the Roodee, is the Huxley Stakes run?
Context: A derby ( or ) is a type of horse race named after the Derby Stakes run at Epsom Downs Racecourse in England.  That was in turn named after Edward Smith-Stanley, 12th Earl of Derby, who inaugurated the race in 1780.  Perhaps the best-known example after the original is the Kentucky Derby in the United States. Ballymore (1969 – 1986) was an Irish thoroughbred racehorse and sire.  A talented although somewhat fragile horse, who was difficult to train, he made only five racecourse appearances but recorded two major victories.  Unraced as a juvenile he made a notable racecourse debut by winning the Irish 2000 Guineas by three lengths in May 1972.  He was beaten in a slowly-run edition of the Gallinule Stakes and then finished third in the Irish Derby before missing the rest of the season.  He ran poorly on his first run as a four-year-old but then defeated Roberto at level weights in the Nijinsky Stakes in May.  He never ran again and was retired from racing at the end of the year.  He had some success as a breeding stallion in Ireland. The Arlington Handicap is an American Thoroughbred horse race held annually since 1929 at Arlington Park racetrack in Arlington Heights, Illinois, a suburb of Chicago, Illinois.  Open to three-year-olds & up, it is currently a Grade III stakes run in July at a distance of 1 ⁄ miles on turf.  It currently offers a purse of $100,000 and serves as the final local prep race for the Arlington Million. The VRC Stakes day (also known as the Emirates Stakes day), is the final day of the Melbourne Spring Racing Carnival at Flemington Racecourse.  Stakes Day is held on the Saturday directly following Melbourne Cup Day (the first Tuesday in November).  The 'Stakes' were first run in 1881 as the Coburg Stakes.  In 2016 the LKS Mackinnon Stakes was moved from the VRC Victoria Derby day and renamed to the Emirate Stakes.  The original "Stakes" were in turn moved to the first Day of the carnival and renamed as the Longines Mile. The Lost in the Fog Stakes is an American ungraded stakes run at Golden Gate Fields in Albany, California for Thoroughbred two-year-old horses.  A five-furlong sprint, the race is named in honor of Lost in the Fog, the brilliant sprinter who made his name between 2004 and 2006 before dying of lymphoma at age four. The August Belmont Trophy is awarded annually to the winning owner of the Belmont Stakes run at Belmont Park in Elmont, New York since 1926.  The perpetual trophy, a silver bowl, made by Paulding Farnham and donated by the Belmont family, has been presented to the winning owner for ceremonial purposes only.  A silver plate is inscribed and given to the winning owner to keep. The Noel J Taylor Memorial Mile is a Group One event for 4 and 5 year old pacing horses in New Zealand.  It is held over the distance of 1700 metres (just over one mile) once a year at Alexandra Park, Auckland, New Zealand.  As well as being a major event in its own right, it is also the key lead-up to the New Zealand Messenger Stakes run the following week.  The race was traditionally a four-year-old race, but from 2013 will be open to five-year-olds, as is the case with all traditional 4 year-old feature races in New Zealand. The Huxley Stakes is a Group 3 flat horse race in Great Britain open to horses aged four years or older.  It is run over a distance of 1 mile, 2 furlongs and 70 yards at Chester in May. Noble Mission (foaled 25 February 2009) is a British Thoroughbred racehorse.  Best known as the younger brother of the unbeaten Frankel in his early career, he later became a very successful racehorse in his own right.  He won the Gordon Stakes as a three-year-old in 2012, but did not reach his peak until 2014.  In 2014, Noble Mission then won the Group 3 Gordon Richards Stakes and Huxley Stakes, before winning his first Group 1 race when beating Magician in the Tattersalls Gold Cup.  He went on to win the Grand Prix de Saint-Cloud in June and the Champion Stakes in October.  He is owned by Khalid Abdullah and was trained by Sir Henry Cecil until Cecil's death in 2013, when Lady Cecil, Sir Henry's widow, became his trainer.
