Setting the bar for excellence
Like the long jump, the name high jump tells you everything you need to know about the event. The high jump is an athletics field event in which competitors have to clear a horizontal bar set at measured heights between two posts. The bar is first set at a low height and then it is moved upwards. A jumper can choose the height at which he or she wants to begin as long as that height is equal or higher than the height set by the event officials. The high jump set-up includes a semi-circular runway allowing the jumper to approach the bar from any angle. After jumping over the bar, the athlete lands in a pit of sand. The current Olympic high jump records to beat in Beijing are 2.39 metres for men (1996 Atlanta) and 2.06m for women (2004 Athens).
