In racing, there are only two seasons – Flat, and Jump (National Hunt) – never mind this ‘spring, summer, autumn, winter’ nonsense.
Racing is a year-round sport with the Flat season taking place between March and October and the National Hunt (or Jump, or ‘the sticks’) season taking place between September and April. (Both types of racing actually take place all year round but the official ‘seasons’ are when you get the big races and majority of meetings for that type of racing.)
British racing supports about 500 professional jockeys and the top ones travel all over the world to ride in races abroad as well. Your average jockey will probably spend more time travelling to races than he does at home, with racing going on every day of the year, all over the country.
