Hurdles are obstacles that athletes must jump over during a race, particularly in track and field events. They are typically made of lightweight materials and are set at specific heights, depending on the level of competition. Hurdles require both speed and technique, as athletes must time their jumps to clear each barrier without losing momentum. In addition to sports, the term "hurdles" can also refer to challenges or difficulties faced in various aspects of life, such as education or career. Overcoming these hurdles often requires problem-solving skills, perseverance, and support from others, similar to how athletes train to improve their performance in events like the 100-meter hurdles.
