Time trials are competitive events where participants race against the clock to complete a specific distance as quickly as possible. Common in sports like cycling and running, athletes start at intervals rather than all at once, allowing them to focus on their individual performance without direct competition. In cycling, for example, time trials can take place on flat roads or hilly terrains, and riders often use specialized equipment to enhance their speed. The fastest time recorded determines the winner, making strategy and pacing crucial for success in these events.
