A "Hurdler" is an athlete who competes in hurdle races, which involve running and jumping over a series of obstacles called hurdles. These races are typically held on a track and vary in distance, with common events being the 110 meters for men and the 100 meters for women. Hurdling requires a combination of speed, agility, and technique to clear the hurdles efficiently while maintaining momentum. Hurdles are standardized barriers that are set at specific heights and distances apart, depending on the event. The sport is governed by organizations like the International Association of Athletics Federations (IAAF), which sets the rules and regulations for competitions. Hurdling is a popular event in track and field competitions, including the Olympic Games.
