F1 race distance and time limits explained
How scheduled laps, elapsed time and stoppages determine when a Grand Prix finishes.

Quick answer
A Grand Prix is scheduled to cover the lap count that reaches the regulatory race distance. If delays or stoppages intervene, the sporting regulations' elapsed-time and suspension limits can cause the race to finish before every planned lap is completed.
From distance to lap count
Because circuits differ in length, each event publishes the number of laps needed to meet the prescribed race-distance framework. The formation lap is not part of the classified race distance.
When the clock matters
The regulations prevent an interrupted or unusually slow race from continuing indefinitely. Once the applicable limit is reached, the leader is shown the chequered flag under the defined procedure.
Stopped races
A red-flag suspension pauses track action but does not create unlimited time. Separate provisions govern the maximum event window and any restart, so severe delays can reduce the final lap total.
