Context paragraphs:
100 metres hurdles: The 100 metres hurdles, or 100-meter hurdles, is a track and field event run mainly by women (the male counterpart is the 110 metres hurdles).  For the race, ten hurdles of a height of 83.8 cm are placed along a straight course of 100 m .  The first hurdle is placed after a run-up of 13 metres from the starting line.  The next 9 hurdles are set at a distance of 8.5 metres from each other, and the home stretch from the last hurdle to the finish line is 10.5 metres long.  The hurdles are set up so that they will fall over if bumped into by the runner, but weighted so this is disadvantageous.  Fallen hurdles do not count against runners provided that they do not run into them on purpose.  Like the 100 metres sprint, the 100 m hurdles begins with athletes in starting blocks.

110 metres hurdles: The 110 metres hurdles, or 110-meter hurdles, is a hurdling track and field event for men.  It is included in the athletics programme at the Summer Olympic Games.  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 weight which slows down the run.  Like the 100 metres sprint, the 110 metres hurdles begins in the starting blocks.
