A team time trial (TTT) is a road bicycle race in which teams of cyclists race against the clock (see individual time trial for a more detailed description of ITT events). The winning team in a TTT is determined by the comparing the times of (usually) the fourth-finishing rider in each team (though the relevant finish position can be otherwise specified in advance by the race organisers). This means that each team will try to get their first four (at least) riders across the finish line in a tight group: it is actually a disadvantage for any rider to finish far in advance of the fourth rider, as by staying back a faster rider can help the fourth rider to get a quicker time.
