Hurdle is a barrier that competitors must jump over in hurdle races. There are three main hurdle events - the 400m hurdle race for both men and women, the 110m hurdle race for men, and the 100m hurdle race for women. The hurdles are positioned so that all runners cover the same distance regardless of their lane. Tracknfield Gear supplies different types of hurdles that athletes can purchase online to practice for hurdle races at school or college.
