The two main highlights of the National Hunt calendar are the Cheltenham Festival meeting and the Grand National meeting. The Cheltenham Festival is held at Cheltenham Racecourse over four days in the second week of March. It features eleven grade one races, culminating in the Cheltenham Gold Cup, the best and most prestigious Chase race in the world, on the Friday. The Grand National meeting is held at Aintree over three days every April. Many of the best horses come to these festivals, which are watched by a huge television audience worldwide. Hundreds of millions of pounds are gambled on these festivals.
