At the professional level, cycling teams are frequently accompanied by motorcycle outriders, team cars and official scrutineers. In a large stage race, the TTT will involve all remaining members of the team, with the time taken when, say, the fifth rider has crossed the line. This encourages a team to keep the minimum number together; the more riders a team has, the more the task of setting the pace can be shared; some teams may sacrifice weaker riders to maintain a higher pace, or strong riders may put in greater efforts over the early part of a course to give their team a good start before dropping off the pace and finishing alone.
