The longest circuit by lap distance to host a Formula One World Championship race was the Pescara Circuit, which hosted a race in 1957, when the road course measured 16 miles (25.8 km). Sections of the circuit ran along a cliff edge, and other sections were hilly, leading many experts to contend that Pescara was the most dangerous F1 track of all time.
