Athletes race against time in track and field events, primarily in sprints and middle-distance races. In these competitions, times are measured to determine winners, with the goal being to complete a distance in the shortest duration possible. Events may vary from the 100 meters to the marathon, showcasing speed and endurance. Runners exert themselves to break personal records and achieve qualifying times for larger events, such as the Olympics. Time is the key factor in establishing rankings and progression to finals, making it a vital aspect of track competitions.
