Longest Grand Prix titles held by two historic races

The 1951 French Grand Prix at Reims holds the record for longest F1 race by distance, covering 601.832 kilometers across 77 laps. Meanwhile, the 2011 Canadian Grand Prix recorded the longest duration at 4 hours, 4 minutes, 39 seconds, including a two-hour red flag stoppage. These records reflect the evolution of racing regulations, with modern races set at a minimum of roughly 305 kilometers. The 2011 race also led to a maximum time limit rule, currently set at three hours. Both records remain unchallenged under current rules.
