The Longest Grand Prix In Formula 1 History​

The longest Grand Prix has two answers depending on how you measure it. By distance, the 1951 French Grand Prix at Reims covered 601.832 kilometres across 77 laps of a 7.8-kilometre circuit, a total that no race since has come close to matching. By duration, the 2011 Canadian Grand Prix at the Circuit Gilles Villeneuve lasted 4 hours, 4 minutes and 39.537 seconds, including a red flag stoppage of approximately two hours caused by torrential rain.

Both records stand for different reasons. The 1951 distance record survived because circuits shortened and lap counts dropped across subsequent decades. Modern F1 races are set at a minimum distance of roughly 305 kilometres, about half the Reims total. The 2011 duration record prompted the FIA to introduce a maximum race time, making it effectively impossible to beat under current regulations.

The 1951 French Grand Prix: 601.832 Kilometres​

The 1951 French Grand Prix took place at Reims-Gueux on 1 July 1951. The circuit measured 7.816 kilometres per lap, and the race ran for 77 laps. Juan Manuel Fangio crossed the line first in an Alfa Romeo 159 with a winning time of 3 hours, 22 minutes and 11 seconds.

The win was shared under the rules of the era. Fangio started in car number 4 but suffered engine trouble after 15 laps. His team ordered Luigi Fagioli to hand over the healthy car number 8, and Fangio drove it to victory across the remaining 57 laps. Fagioli, who was 53 years old at the time, became the oldest driver to win a World Championship Grand Prix, a record that still stands more than 70 years later. He was so furious at being forced to give up his car that he retired from Grand Prix racing immediately after the race.

The Pescara circuit in Italy, used for the 1957 Pescara Grand Prix, holds the record for the longest individual lap in F1 history at 25.579 kilometres. But with only 18 laps, the total race distance of 460 kilometres falls well short of the Reims record. Longer laps do not produce longer races when the lap count is low.

The 2011 Canadian Grand Prix: 4 Hours and 4 Minutes​

The 2011 Canadian Grand Prix at the Circuit Gilles Villeneuve in Montreal is the longest Formula 1 race ever measured by total elapsed time. The race lasted 4 hours, 4 minutes and 39.537 seconds across 70 laps, though that figure includes a red flag period of approximately two hours caused by heavy rain.

The safety car was deployed six times during the race, a record at the time. Jenson Button collided with his McLaren teammate Lewis Hamilton on lap 8, putting Hamilton out of the race. Button later hit Fernando Alonso on lap 37, punctured his own tyre, and dropped to last place out of the 21 remaining cars. He then drove from 21st to first over the remaining laps, making six pit stops in total, also a record for a race winner. He passed Sebastian Vettel for the lead when the Red Bull ran wide at Turn 6 on the final lap, winning at an average speed of just 74.864 km/h.

The duration of the 2011 race directly triggered a rule change. The FIA introduced a maximum time limit of four hours for the 2012 season, then reduced it to three hours from 2021 onward. Under current rules, no race can exceed two hours of green-flag racing time or three hours of total elapsed time including stoppages. The 2011 Canadian Grand Prix will almost certainly never be beaten.

The Longest Runs In Five Seasons Of Data​

The word “longest” applies beyond historical records. Across five seasons of measured timing data from 2022 to 2026, three benchmarks define the extremes.

The longest clean stint in the dataset is 69 racing laps on a single set of hard tyres, recorded at the 2024 Monaco Grand Prix. Charles Leclerc, Lando Norris, Oscar Piastri and Carlos Sainz all ran 69 measured green-flag laps on one compound, with four more drivers at 68. A lap-one red flag gave the entire field a free tyre change under the stoppage, and the leading drivers then nursed a single set across the remaining distance. The longest stint in five seasons of data belongs to four drivers at once, all completing a full Grand Prix on one set of rubber.

The longest pit lane in Formula 1 belongs to Imola, with an era median transit of 30.2 seconds from entry line to exit line. It is the only pit lane in the sport that breaks the 30-second barrier, ahead of Silverstone and Singapore at 29.1 seconds each and Qatar at 28.6 seconds. Imola also produces the era’s most expensive total stop at 28.1 seconds: the longest transit and the dearest pit visit from the same circuit. The shortest pit lane transit by comparison is Albert Park at just 18.1 seconds.

The longest single pit stop measured in the dataset is Esteban Ocon’s 49.9-second visit at the 2026 Chinese Grand Prix, documented in the same pit stop analysis.

F1 Race Length FAQs​

What is the longest F1 race in history?​

By elapsed time, the longest F1 race is the 2011 Canadian Grand Prix at 4 hours, 4 minutes and 39 seconds, a figure that includes a two-hour red flag suspension for rain. Jenson Button won after falling to last place during the race, completing six pit stops and passing Sebastian Vettel on the final lap. By distance, the longest is the 1951 French Grand Prix at 601.832 kilometres across 77 laps of the Reims-Gueux circuit. The winning car was shared by Juan Manuel Fangio and Luigi Fagioli under the shared-car rules of the era.

What is the longest track in F1 2026?​

The longest track on the 2026 Formula 1 calendar is Spa-Francorchamps in Belgium at 7.004 kilometres per lap. Las Vegas is second at 6.201 kilometres, followed by Baku at 6.003 kilometres and Silverstone at 5.891 kilometres. Historically, the longest circuit ever used in a World Championship race was the Pescara circuit in Italy at 25.579 kilometres, used for a single Grand Prix in 1957.

Is there a time limit for F1 races?​

F1 races are subject to two time limits. The racing clock, which pauses during red flags, cannot exceed two hours. The total elapsed time including all stoppages cannot exceed three hours. When either limit is reached, the race finishes at the end of the lap the leader is on. The three-hour limit was introduced in 2021, reduced from a four-hour cap that had been in place since 2012. Before 2012, there was no maximum total time, which is how the 2011 Canadian Grand Prix lasted over four hours.
