For both men and women, the normal long hurdle race distance is 400 meters. Each of these races consists of 10 hurdles and is an Olympic event. The men's 200 meter low hurdles event was on the Olympic athletics program during the Summer Olympics in 1900 and 1904. It was not included in 1932 because of time constraints (the men's 100 meter dash was added). In 1996, it was revived as an exhibition event. The women's 300 meter low hurdles event was on the Olympic athletics program from 1920 to 1928 and again in 1936. It was dropped in 1952 because of time constraints (the women's 200 meter dash was added). In 1960, it was revived as an exhibition event. In conclusion, there are ten hurdles in each race.
