Aintree Racecourse is a racecourse in Aintree, Merseyside, England. The racecourse is best known for annually holding the world-famous Grand National steeplechase. It is regarded as the most difficult of all courses to complete successfully, with 16 steeplechase fences including renowned obstacles the Chair, Foinavon, Valentine's, Canal Turn and Becher's Brook. These are so infamous that even their names strike fear into the most professional of jockeys. All fences bar the water jump are covered with spruce, unlike at any other course in British National Hunt racing.
