A team time trial involves a group of riders attempting to complete it in the shortest time possible. The riders alternate in front, letting the others draft behind in order to conserve their strength.
TTTs observe how fast a team collaborates. The timing is typically taken when a specified number of members in a group—the fourth most frequent—pass the finish line. Collaboration, speed, and communication are crucial to winning. TTTs may occur in road racing and in competitions that have only time trials. It illustrates the necessity of teamwork and that drafting improves speed.
