Hurdle race

Hurdle race is a type of track and field race.
There are "sprint" hurdle races and "long hurdle" races. The standard sprint hurdle race is 110 meters for men and 100 meters for women. Men and women run 400 meters in the standard long hurdle race. Each of these races is run over ten hurdles and they are all Olympic events.
Other distances are sometimes run, particularly indoors. The sprint hurdle race indoors is usually 60 meters for both men and women, although races 55 meters or 50 meters long are sometimes run.
