Coordinates: The Cheltenham Festival is a meeting in the National Hunt racing calendar in the United Kingdom, with race prize money second only to the Grand National. It is an event where many of the best British- and Irish-trained horses race to an extent which is relatively rare during the rest of the season.
The festival takes place annually in March at Cheltenham Racecourse in Cheltenham, Gloucestershire. The meeting usually coincides with Saint Patrick's Day, and is particularly popular with Irish visitors.
It features several Grade I races including the Cheltenham Gold Cup, Champion Hurdle, Queen Mother Champion Chase and World Hurdle, held over four days. Large amounts of money are gambled during Cheltenham Festival week, with hundreds of millions of pounds being bet over the week. Cheltenham is often noted for its atmosphere, most notably the "Cheltenham roar", which refers to the enormous amount of noise that the crowd generates as the starter raises the tape for the first race of the festival.
The Cheltenham Festival originated in 1860 when the National Hunt Chase was first held at Market Harborough. It was initially titled the Grand National Hunt Meeting and took place at several locations since its institution, at the turn of the 20th century it was mostly held at Warwick Racecourse. In 1904 and 1905 it was staged at Cheltenham over a new course established at Prestbury Park in 1902, having previously taken place at Cheltenham in 1861. From 1906 to 1910 it was again held at Warwick but further additions and major improvements made at Cheltenham by Messrs. Pratt and Company, including a new stand(the fourth one), miles of drain to prevent unsuitable racing ground, tar paving in the enclosures and the paddock extended to 35 saddling boxes, proved enough to make the National Hunt Committee decide on that the 1911 meeting was to return at Prestbury Park, Cheltenham where it remained to the present day. The earliest traceable reference to a "Festival" is in the Warwick Advertiser of 1907.
The Stayers Hurdle, first ran in 1912, is the oldest race from the Cheltenham festival that is currently a championship race. The Gold Cup, established in 1924, was originally a supporting race for the County Hurdle which was the main event of the first day but that quickly changed and in the following seasons it became a championship race, however for many years it was still used by the trainers as a preparation race for the Grand National. The Champion Hurdle first ran in 1927 and the Queen Mother Champion Chase in 1959, were both championship races from the time they were introduced unlike the Stayers Hurdle and Gold Cup.
In 1987, 21 year old Gee Armytage became the first female jockey to win a race at the festival on 17 March 1987. She won the Kim Muir Challenge Cup, back then held on Tuesdays and backed it with another victory the next day in the Mildmay of Flete Challenge Cup on a horse aptly-named Gee-A. 
In 2001 the Festival was cancelled due to an outbreak of foot-and-mouth disease in Britain. The meeting had initially been postponed to April, but when a case of the disease was confirmed locally, putting the racecourse within an exclusion zone, all racing had to be called off.
In 2008, the second day of the festival was cancelled due to heavy storms. The races scheduled for that day were instead run on the third and final days of the festival.
Until 2005 the festival had traditionally been held over the course of three days, but this changed with the introduction of a fourth day, meaning there would be one championship race on each day, climaxing with the Gold Cup on the Friday. To ensure each days would still have six races, five new races were introduced. Two further races have since been added, bringing the total to 26 races overall, with grade one events including the Champion Bumper, Triumph Hurdle, Ryanair Chase, Supreme Novices' Hurdle, Neptune Investment Management Novices' Hurdle, Arkle Challenge Trophy, RSA Chase, Champion Hurdle, World Hurdle, Queen Mother Champion Chase and the feature race, the Gold Cup.
The festival also includes one of the two biggest Hunter Chases of the season, the Foxhunters', which is run on the Friday over the same course as the Gold Cup, and is sometimes referred to as the "amateurs' Gold Cup".
Unlike Royal Ascot and many other top flat racing events in Britain and Ireland, the Cheltenham Festival does not have a history of attracting many international contenders, though French-trained horses have done well - Baracouda being perhaps the most well-known, having landed the World Hurdle twice.
The 2010 Cheltenham Festival had the first ever running of the Ladies Charity Flat Race in aid of Cancer Research UK. The race was contested over 1 mile 5 furlongs, and all 12 amateur jockeys were female. The race was won in a photo-finish in front of a packed Cheltenham grandstand by Dublin-based Orna Madden riding Prince Picasso, finishing just ahead of fellow Irish rider Katie Doyle riding Devil To Pay, with Helen Needham riding on Mr. Wall Street in third.
230,000 racegoers and £250 million is expected to be wagered at the 2014 Cheltenham Festival.
For several years there have been concerns about the number of equine injuries and fatalities. In 2006, 11 horses died and in response the racecourse decreased the number of runners in certain races and re-sited one of the more difficult fences.
On the opening day of the 2012 festival, three horses had to be euthanised after suffering bone fractures or breaks, including two during the Cross-Country Chase, becoming the second and third equine fatalities in that race since 2000. There were two further equine fatalities during the festival, and some critics claimed races should not have gone ahead due to the firmness of the ground following exceptionally dry weather. The RSPCA suggested that guidelines be reviewed, while the British Horseracing Authority stated that "with over 90,000 runners a year [in British horse racing], some accidents and sadly some injuries are inevitable."
The number and type of races at the Cheltenham Festival has changed dramatically over the years of its existence. In particular, it has grown from a two-day meeting to a four-day meeting. In 2015, there were 27 races as follows:
