a rider intentionally sacrificing his chances of winning a sprint, so that a teammate can ride in his draft until ready to begin the final sprint.

To sprint in front of another rider, almost always a teammate, so that rider can take advantage of the draft for a time, before coming past with an even faster sprint toward the finish.

Sprinting technique often used by the leadout man where the rider will accelerate to maximum speed close to the sprint point with a teammate, the sprinter, drafting behind, hoping to create space between the sprinter and the pack. When the leadout man is exhausted he will move to the side to allow his teammate to race in the sprint. Often a line of leadout men will be used to form a leadout train to drive the speed higher and higher (and to reduce the chances of other riders attacking) over the closing stages of a race. The purpose of a leadout is for the sprinter to achieve high speed at the sprint approach using as little of his own energy as possible, so he has as much energy as possible for the final sprint.[ edit

On a single-layer disc or PTP dual-layer disc, the physical area 1.0 mm or wider toward the outside of the disc following the data area. On an OTP dual-layer disc, the physical area 1.2 mm or wider at the inside of the disc following the recorded data area (which is read from the outside toward the inside on the second layer).

On a CD, it is the area after the last track on the disc and can be used to store information to instruct the player to stop playing or go to the beginning of track one.

An area at the end of a session that indicates that the end of the data has been reached. The first lead-out on a disc is 6750 sectors (1.5 minutes, about 13 megabytes) long; any subsequent lead-outs are 2250 sectors (.5 minute, about 4 megabytes). Writing the lead-out closes the session. CD-ROM drives and CD audio players cannot see the data/audio in a session until the session is closed.
