So, having had the pleasure of walking Monaco last year, and driving round Silverstone for their annual lap of lights, I got wondering… which F1 Grand Prix track is the longest?
Depending on whether you’re looking for the all time record holder or the longest track currently in use, the answer changes significantly.
The All-Time Record: Pescara Circuit
The longest track to ever host a Formula 1 Grand Prix was the Pescara Circuit in Italy.
- Length: 25.8 km (16.032 miles).
- The Race: It only hosted a single world championship F1 race, the 1957 Pescara Grand Prix.
- The Vibe: It was a terrifying public-road circuit that ran through the city, up into the hills, and back down two massive 6 km straights. To put its size in perspective, it is longer than the famous Nürburgring Nordschleife (which is roughly 22.8 km).
The Current Record Holder: Spa-Francorchamps
On the modern F1 calendar, the Circuit de Spa-Francorchamps in Belgium is the undisputed heavyweight.
- Length: 7.004 km (4.352 miles).
- Context: While it’s the longest today, the original 1950s version of Spa was nearly 15 km long. It was eventually shortened to the current layout for safety reasons, but it remains the only track on the modern schedule that exceeds 7 km.
