Jumping events were included in the Olympic program in Paris in 1900, but were subsequently removed until the 1912 Games in Stockholm. Since then, this sport has been on the Olympic calendar with remarkable consistency. The only exceptions are the 1936 and 1948 games, when horse racing was held as part of the Berlin Olympics and Moscow Olympics, respectively. Horse racing is known by many names around the world: racehorse, thoroughbred, harness race, steeplechase. But its central feature is always the same: two horses and a jockey competing for glory and prize money. The most prestigious event is called the Grand National. It's one of the three major races that make up British horse racing, along with the Derby and the Oaks. The Grand National is run over a distance of about twenty-five miles (forty kilometers) at Aintree Racecourse in Liverpool. The other major horse racing nation in Europe is France, where the Grand Prix is the most popular race. It's held every year at Longchamp Racecourse in Paris and can be viewed on television during the week leading up to the event. In North America, there are several important races, including the Kentucky Derby, the Preakness Stakes, and the Belmont Stakes.
