Hurdling 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. The standard long hurdle race is 400 meters for both men and women. 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. A 60 meter indoor race is run over 5 hurdles. A shorter race may occasionally have only 4 hurdles. Outdoors, a long hurdle race is sometimes shortened to 300 meters for high school races over 8 hurdles (spaced distance-wise identical to the beginning of a standard 400 meter race), and 200 meter races for middle school and younger divisions over 5 hurdles (spaced in the same position as the last 5 hurdles of a standard 400 meter race). Masters age divisions also run a permutation of 300 meters with 7 hurdles (in the same position as the last 7 hurdles of a standard 400 meter race) and 200 meters with 5 (spaced the same as for the youth) for older age divisions.
