must keep both feet together and clear 10 hurdles on the 110m hurdles track. In 2002, Kengo Shiomi (JPN) won this event in the heats, despite never having taken part in the event before. International skids Contestants take a short run-up to a lubricant-coated track, on which they skid. Skids only count if the contestant does not fall over. The lubricant coating of the track was changed for the 2004 competition, from olive oil to xanthan gum. This led to the world record being broken three times in the first heat. The current record is held by Brian Clark (GB), and is around 55 metres. Pool hang Contestants must hang onto a bar suspended above a swimming pool for as long as possible. They can only use their hands to grip the bar. The event is done as a knockout with contestants competing in pairs. The winning contestants in the heats meet in a final to decide first place, with the losers competing for third place. Tennis whack This event has contestants competing using a tennis racquet and a tennis ball. The aim is to see who can hit the ball vertically up in the air the longest time. This is measured in seconds. This is also sometimes known as "Screeding". Speed-gun run Contestants sprint down a twenty-metre track; their speed is measured close to the end, just before they run into an upright crash mat. The current world record of 20.27 mph (32.62 km/h) is held by Hugo 'The Human Rhino' Mybergh (RSA). Under hurdles This event is identical to the 110 metres hurdles track event, except that the competitors must go under the horizontal bar of the hurdle instead of over it. This makes the event more difficult, and the times taken to complete the course are greater than standard hurdling times. International hurdler Liam Collins smashed the world record dipping his way to a staggering 19.62. Underwater shot put This is identical to the track and field event, shot put (throwing a ball with a pushing motion), except that it takes place under water. Rather than being made of metal, the shot used is a leather ball filled with sand. Competitors can achieve distances of 4 m and more. Uphill long jump Vertical standing jump Contestants must jump from standing onto a table-like platform. There is no run-up, and no bouncing is allowed; momentum is gained primarily
