A gameplay option in most modern racer video and computer games. It usually involves trying to complete a track within a specified amount of time, or trying to go for as long as possible without time running out, which is replenished by checkpoints throughout the track.

Mario Kart 64 started a trend in which players could record their best times, and then race against a "ghost", which followed the exact path the player followed the previous time. This way the player knew that if he/she was beating the ghost, then they were also setting a new record.
