what is the distance of an f1 race
Formula One racing Thirty minutes prior to race time, the cars take to the track for any number of warm-up laps (formally known as reconnaissance laps), provided they pass through the pit lane and not the grid, after which they assemble on the starting grid in the order they qualified.[18] At the hour of the race, a green light signifies the beginning of the relatively slow formation lap during which all cars parade around the course doing a final tire warmup and system checks.[18] The cars then return to their assigned grid spot for the standing race start. The starting light system, which consists of five pairs of lights mounted above the start/finish line, then lights up each pair at one-second intervals. Once all five pairs are illuminated, after a random length of time (one to nine seconds), the red lights are turned off by the race director, at which point the race starts.[19] The race length is defined as the smallest number of complete laps that exceeds 305 kilometers (the Monaco Grand Prix is the sole exception with a race length of 78 laps / 260.5Â km),[20] though occasionally some races are truncated due to special circumstances. The race can not exceed two hours in length; if this interval is reached the race will be ended at the end of the next full lap. The only exception is if the race is halted by a Red flag in which case the total time including the red flag stoppage must not exceed 4 hours (since 2012), and the total time excluding the red flag stoppage may not exceed 2 hours.[21]
