Hurdle races are a type of track and field event where athletes run a specific distance while jumping over a series of obstacles called hurdles. These hurdles are set at a standard height and are spaced evenly along the track. The goal is to complete the race in the fastest time possible while clearing each hurdle without knocking them down. There are different distances for hurdle races, with the most common being the 110-meter hurdles for men and the 100-meter hurdles for women. Additionally, there is the 400-meter hurdles, which combines sprinting with longer distances and requires athletes to maintain speed while navigating the hurdles.
