Formula 1 returns to one of its most legendary venues next weekend as the teams head to Spa-Francorchamps for the 2026 Belgian Grand Prix, widely regarded as one of the toughest tests on the calendar. Often described as the “university of Formula 1,” Spa challenges drivers and engineers with its unique combination of high-speed corners, long straights, dramatic elevation changes and unpredictable weather.

At 7.004 kilometres, Spa is the longest circuit in Formula 1 and has hosted the World Championship since 1950. Located in Belgium’s Ardennes forest, the track’s unique microclimate can create rapidly changing conditions, with rain affecting only parts of the circuit at times. These mixed conditions make tyre selection particularly challenging, with teams often forced to choose carefully between slicks and intermediate tyres.

Pirelli will supply the C2, C3 and C4 compounds for the weekend. Spa places significant demands on tyres due to heavy loads and high-speed corners, particularly through the famous Eau Rouge and Raidillon sequence before the fast run onto the Kemmel Straight. Recent resurfacing and track activity from the 24 Hours of Spa should influence grip levels, with conditions expected to evolve throughout the weekend.

The circuit’s three sectors require different setup approaches. The first sector rewards straight-line speed, the second focuses on technical cornering, and the final sector combines flowing corners with elevation changes. New aerodynamic regulations may help teams find a better compromise between downforce for corners and efficiency on straights.

Weather and temperatures could also shape the race strategy. High track temperatures may increase tyre degradation and raise the possibility of two-stop strategies, with harder compounds expected to play an important role.

Last year’s Belgian Grand Prix was heavily affected by rain, with the start delayed for over an hour before racing resumed behind the Safety Car. Drivers eventually switched from intermediates to slick tyres, creating a strategic challenge.

The 2026 event marks the 71st Belgian Grand Prix. Spa has hosted 58 editions, with Michael Schumacher holding the record for most victories at the circuit with six wins. Lewis Hamilton and Ayrton Senna each have five victories, while Ferrari remains the most successful constructor with 18 Belgian Grand Prix wins.
