hurdles

A hurdle is an obstacle designed to be jumped over. In athletics, hurdle races require competitors to clear a sequence of barriers while maintaining speed and staying in their lanes. The term can also denote any obstacle to be overcome.

In track and field, the main adult events are the 100 meters hurdles for women, the 110 meters hurdles for men, and the 400 meters hurdles for both sexes. Standard heights are 84 cm (women’s 100 m), 106.7 cm (men’s 110 m), and 91.4 cm (400 m for both). Hurdles are placed on a straight section of the track with fixed spacing, and athletes must stay in their lanes between hurdles.

Technique emphasizes speed and efficient clearance. Athletes take off near the hurdle, lead with a straight front leg, and sweep the trailing leg beneath in a compact motion to minimize disruption of forward momentum. Rhythm and stride between hurdles are crucial, especially in the sprint distances.

Rules require competitors to stay in their lanes and to clear each hurdle. False starts are penalized, and deliberate interference or lane violations can lead to disqualification. Fouls related to contact with another athlete can also end a race.

Equipment and layout: Hurdles are lightweight frames with a padded crossbar and adjustable heights. Competition rules specify standard hurdle spacing and track markings for each event, with different hurdle counts depending on the distance.

History: Hurdling arose in early track competitions and was standardized in the late 19th and early 20th centuries. It is now a core part of national championships and the Olympic Games, governed by World Athletics.

In general usage, a hurdle is any challenge or obstacle that must be overcome to achieve a goal.
