How many kilometres and laps is an F1 race?
Why a Grand Prix is about 305 km, why Monaco is shorter and what happens with the two-hour limit.
Summary
- A Grand Prix is set at 305 km or slightly more: the number of full laps needed to exceed that distance is calculated.
- Monaco is the exception, at 260 km.
- A race lasts up to about two hours; with red flags there is a larger total limit.
Step by step
305 km
The minimum distance of a Grand Prix is around 305 km. It is divided by the circuit length and rounded up to full laps, which is why each track has a different number of laps.
The Monaco exception
Its layout is very short (3.337 km) and reaching 305 km would exceed the time limit, so it is run over 260 km (78 laps).
The two-hour limit
The race is stopped when the maximum time runs out, which on a normal weekend is around two hours, although sources differ on how the final lap is applied: check the FIA sporting regulations.
Red flags
With a suspended race, a larger total limit from the original start comes into play (three hours according to some sources).
