The invention discloses a racetrack board for the track and field competition terrain and relates to the field of track and field. The racetrack board comprises a racetrack board body, a receiver, a transmitter, a processor and an embedded part. A projection mechanism is arranged in the racetrack board body. The transmitter is arranged in the embedded part. The receiver is arranged at the bottom of the racetrack board body. The projection mechanism is electrically connected with the embedded part through the processor. A combination part is arranged on the end surface of the embedded part. When the racetrack board body is combined with the combination part, the receiver is positioned within the working range of the transmitter. During the construction of a runway, the embedded part can beembedded into a corresponding part of the runway. Meanwhile, the transmitter stores the corresponding runway information. Before a track and field competition, a worker combines the racetrack board body with the combination part in the embedded part, so that the receiver receives the runway information in the transmitter. In this way, the projection mechanism displays the runway information. The worker does not need to specially identify numbers on the racetrack board. The time is saved, and the phenomenon of mistakes during placement is completely eradicated.
