Prix Niel
The Prix Niel is a Group 2 flat horse race in France open to three-year-old thoroughbred colts and fillies. It is run at Longchamp over a distance of 2,400 metres (about 1½ miles), and it is scheduled to take place each year in September.
The race serves as a trial for the Prix de l'Arc de Triomphe, which is held at the same venue three weeks later.
History
A precursor of the race called the Prix de Chantilly was formerly staged at Chantilly in early September. It was open to horses aged three or older, and for a period its distance was 3,100 metres. It was subsequently transferred to Longchamp and run over 3,000 metres. It was shortened to 2,400 metres in 1952, and reduced to 2,300 metres in 1953.
The Prix de Chantilly was restricted to three-year-olds when a separate event was introduced for older horses in 1955. The new race was initially titled the Prix Henri Foy, and from this point the Prix de Chantilly was contested over 2,400 metres.
The race was cut to 2,000 metres in 1960, and restored to 2,400 metres the following year. It was switched to Chantilly in 1964, and returned to Longchamp with a length of 2,100 metres in 1966. It was extended to 2,200 metres in 1968.
