races of five furlongs were run on a straight course which ran diagonally across the centre of the Mildmay course. On this course on 7 April 1967, on the day before the Foinavon Grand National, on his first visit to Aintree, the two-year-old Red Rum, ridden by Paul Cook, dead-heated with Curlicue in a five-furlong selling plate. The running rails for this course remained in place until 1987. The Grand National The Grand National race was run for many years over 4 miles 856 yards (4 miles 3 furlongs 196 yards), then 4 miles 4 furlongs. In 2013 the start was moved 110 yards to keep the horses away from the noise of the crowd before the start. The distance of the race is now after being re-measured by the British Horseracing Authority in 2015. The race is considered among the most demanding steeplechases in the world. The lead has often changed hands during the run-in after the final fence. There are usually 40 horses taking part in the race (this has been the maximum since 1984) but fewer than ten may actually complete the course: for example, 42 horses started in 1928, and only two reached the finishing post. The record for the most victories in the Grand National is held by Red Rum, who won three times in the 1970s, in addition to coming second twice. Notable races Other events Motor racing Aintree has also been used as a venue for motor racing. The British Grand Prix was staged there on five occasions, in 1955, 1957, 1959, 1961 and 1962. In addition to the Grand Prix, the circuit also held 11 non-championship Formula 1 races, known as the Aintree 200, first won by Stirling Moss in 1954 with the last winner being Jack Brabham, in April 1964. The only driver to have competed in both horse and motor races at Aintree is Alfonso de Portago, who rode in the Grand National in 1950 and 1952 as well as driving a Ferrari 750 Monza in the Daily Telegraph International Meeting in October 1955. He was set to compete at the 1957 British Grand Prix at Aintree, but he was killed in the Mille Miglia in May of that year. Music Michael Jackson concluded the European leg of his 1987–1989 Bad World Tour at the venue on 11 September 1988, to more than 125,000 people. Also Jackson planned to perform
