What Is the Longest F1 Track? Spa vs Pescara
Spa is the longest F1 track on the 2026 calendar at 7.004 km. Pescara holds the all-time World Championship record at approximately 25.8 km.
Spa-Francorchamps is the longest F1 track on the 2026 calendar, at 7.004 km (about 4.352 miles) per lap. But the all-time answer is Pescara in Italy, which hosted a World Championship Grand Prix in 1957 on a road course approximately 25.8 km (16 miles) long. Formula 1 identifies Spa as the current calendar’s longest circuit; Guinness World Records lists Pescara as the historical record holder.
Here, “longest” means the distance around one lap, not the total race distance or the time needed to finish a Grand Prix.
| Scope | Longest circuit | Country | Lap length |
|---|---|---|---|
| 2026 F1 calendar, as of 1 October | Spa-Francorchamps | Belgium | 7.004 km / approximately 4.352 miles |
| Any F1 World Championship race | Pescara | Italy | Approximately 25.8 km / 16 miles |
Spa: the longest current F1 circuit
Spa’s modern layout was created through redevelopment in 1979. It is substantially shorter than the original public-road circuit, but still tops today’s calendar. Its length combines long straights with fast corners, including the climb through Eau Rouge and Raidillon. F1’s circuit guide also notes a practical consequence of its size: one part of the track can be wet while another remains dry.
For scale, the Las Vegas Strip Circuit measures 6.201 km, while Baku measures 6.003 km. Spa is 803 metres longer per lap than Las Vegas and 1.001 km longer than Baku, using those published lengths.
Pescara: the longest in World Championship history
Pescara was a temporary road course on Italy’s Adriatic coast, combining long straights with a winding inland section through villages. It held World Championship status only in 1957, although racing there began much earlier. Motor Sport’s circuit history corroborates its status as the longest circuit ever to host a championship F1 race.
The official result records Stirling Moss winning for Vanwall on 18 August 1957, completing 18 laps in 2:59:22.700. A small lap count therefore did not mean a short race. Formula 1’s result archive supplies the date, winner, laps and elapsed time.
Historical sources differ on the precise lap distance: Guinness gives 25.8 km, while Circuits of the Past gives 25.579 km. That discrepancy does not change the record holder. This article uses Guinness’s figure, labelled approximate, rather than presenting either measurement as uncontested.
Why the longest track does not mean the longest race
Under Article B2.5.2 of the 2026 FIA Sporting Regulations, a normal Grand Prix uses the fewest complete laps exceeding 305 km; Monaco instead uses 260 km. A longer circuit therefore generally requires fewer laps, rather than a proportionally longer race. The FIA regulations also provide for lap reductions when formation laps begin behind the Safety Car.
At Spa, dividing 305 by 7.004 gives approximately 43.55 laps, explaining the standard 44-lap schedule listed in F1’s Belgian Grand Prix guide. For the separate question of elapsed time and shortened races, see how long a Formula 1 race lasts.
