Time trial

In many racing sports an athlete (or occasionally a team of athletes) will compete in a time trial against the clock to secure the fastest time. In cycling, for example, a time trial (TT) can be a single track cycling event, or an individual or team time trial on the road, and either or both of the latter may form components of multi-day stage races. In contrast to other types of races, athletes race alone since they are sent out in intervals (interval starts), as opposed to a mass start.
