How long is one lap of the 2026 Belgian Grand Prix circuit?

One lap of the 2026 Belgian Grand Prix circuit measures 7.004 kilometres. That distance refers to the current Grand Prix layout of the Circuit de Spa-Francorchamps in Belgium, which is the longest circuit on the 2026 Formula One calendar.

Spa’s length is a major part of its character. The lap climbs and drops through the Ardennes, combining slow corners, long straights and very high-speed sections. Drivers pass through famous places such as La Source, Eau Rouge and Raidillon before accelerating along the Kemmel Straight toward Les Combes. The lap then winds through the middle sector and returns through Blanchimont toward the final chicane.

Readers sometimes confuse the modern 7.004-kilometre circuit with Spa’s original public-road course. The first layout, used from the 1920s, was roughly 14 kilometres long and linked several towns. It was substantially shortened and redesigned for modern safety standards, with the current permanent circuit emerging after redevelopment in 1979.

The lap figure also explains why a Belgian Grand Prix requires fewer laps than many other races. The 2026 event was listed over 44 laps, producing a race distance of about 308 kilometres. Small differences in published totals can result from rounding or source-specific timing data, but 7.004 kilometres is the standard circuit-length figure.
