The female counterpart is the 100 metres hurdles. As part of a racing event, ten hurdles of 1.067 metres (3.5 ft or 42 inches) in height are evenly spaced along a straight course of 110 metres. They are positioned so that they will fall over if bumped into by the runner. Fallen hurdles do not carry a fixed time penalty for the runners, but they have a significant pull-over
100 metres hurdles run. From 1926 until 1968 on only the 80 m distance was run. For the 80 m race women had to clear eight hurdles placed at a distance of 8 metres from each other and a height of 76.2 cm. Just like with the men's races, until 1935 no more than three hurdles could be knocked over (or the runner was disqualified) and records were only officially registered if the runner had cleared all her hurdles clean. In 1935, this rule was abandoned, and L-shaped hurdles were introduced that fell over forward easily and greatly reduced the risk of injury
