Also to celebrate the Dubai Duty Free Shergar Cup, Ascot has recreated the figure of a giant racehorse, cleverly contorted out of 10 acrobats, crossing the winning post at the Racecourse.
The 'human racehorse' took seven hours to create and is ridden by German jockey, Stefanie Hofer, who will be making her debut at the race day as part of the Girls team, alongside Canadian Emma-Jayne Wilson and Brit Hayley Turner.
Watch the video to see how the 6ft figure was formed http://www.ascot.co.uk/con-horse-tionist Grandstand Admission for the Dubai Duty Free Shergar Cup is available from £20 in advance.
