hurdle
A "hurdle" is an obstacle or barrier that must be overcome, often used in the context of sports. In track and field, hurdles are physical barriers that athletes jump over during a race, known as the hurdles race. The goal is to complete the race in the fastest time while successfully clearing each hurdle.
In a broader sense, hurdles can refer to challenges or difficulties in various aspects of life, such as personal goals or professional projects. Overcoming these hurdles often requires determination, strategy, and sometimes support from others, making them a common metaphor for life's challenges.
