The first London Marathon was held on 29 March 1981, more than 20,000 applied to run. 6,747 were accepted and 6,255 crossed the finish line on Constitution Hill. The Marathon's popularity has steadily grown since then. As at 2009, 746,635 people have completed the race since its inception. In 2010, 36,549 people crossed the line, the biggest field since the race began. The first wheelchair marathon race was held in 1983 and the event was credited with reducing the stigma surrounding disabled athletes. In 2013 the IPC Athletics Marathon World Cup was held within the London Marathon featuring athletes of both genders in the T42–T46 and T11–T13 categories. In August 2013 it was announced that the event would be staged in London until 2017 and feature athletes in the T11-T12, T13, T42-T44, T43, T45-46, T51-52 and the T53-54 class.
