A track hurdle is a standard obstacle used in hurdle races, where athletes sprint and clear a series of evenly spaced barriers. Typically made with a metal frame and a horizontal bar that can be adjusted in height, the hurdle is designed to tip over if hit, minimizing the risk of injury. Hurdling tests a runner’s speed, agility, and form, and is featured in events like the 110m hurdles and 400m hurdles.
