Riders in a team follow each other closely in line, drafting to minimize total drag, and periodically the lead rider (who works the hardest) peels off the front, swings up the track banking and rejoins the team at the rear. The position of the third rider is pivotal because final times are measured as the third team member's front wheel crosses the finishing line. Since the winning team is decided by the third rider, it is common for one rider to take a "death pull", pedaling very hard before the finish to tow the teammates, which means that this rider cannot maintain the group-pace afterwards.
