Located in Heusden-Zolder in Belgium’s Limburg region, Circuit Zolder is one of the country’s most important post-war racing venues.
Opened in 1963, the circuit became Belgium’s principal Formula One home during much of the 1970s and early 1980s, temporarily replacing Spa-Francorchamps as the host of the Belgian Grand Prix. Unlike Spa’s vast, high-speed road course character, Zolder offered a tighter, more technical challenge, with an undulating layout that demanded precision under braking and through quick direction changes.
Although its F1 history was relatively brief, Circuit Zolder remains a significant part of Belgian motorsport, continuing to host major touring car, endurance and truck racing events today.

Circuit
When was Circuit Zolder built?
Circuit Zolder opened on 19 June 1963 and was built in Heusden-Zolder, Belgium.
Originally known as Circuit Terlamen, the venue was developed as a permanent road course and quickly established itself as one of Belgium’s major racing circuits. The original configuration measured just over 4.1 km, and over the years, the layout was revised several times to improve safety and adapt to modern racing categories.
The track is known for its undulating profile and compact nature. Rather than relying on very long straights, Zolder combines medium-speed corners, heavy braking zones and technical sections that reward accuracy and rhythm.
When was the first Belgian Grand Prix at Circuit Zolder?
Circuit Zolder first hosted the Belgian Grand Prix in 1973. Formula One raced there on ten occasions, 1973, 1975–1982 and 1984.
During this period, Zolder effectively became Belgium’s main Formula One venue, with Spa-Francorchamps temporarily dropping off the calendar apart from isolated returns.
The circuit’s Formula One era included victories for several major names, but it is also closely associated with one of the sport’s most tragic moments. During qualifying for the 1982 Belgian Grand Prix, Gilles Villeneuve suffered a fatal accident after his Ferrari collided with Jochen Mass’s March at high speed.

Formula One returned once more in 1984, when Michele Alboreto won for Ferrari. After that, the Belgian Grand Prix moved permanently back to Spa-Francorchamps from 1985 onward.
What makes Circuit Zolder special?
Zolder’s challenge comes from its technical nature.
It is not a pure power circuit, nor an ultra-slow street-style venue. Instead, it demands confidence through a series of linked corners and disciplined braking into its tighter sections. Its slightly rolling terrain adds character to the lap, and in later decades the circuit became particularly well suited to touring cars, GT racing and national endurance events.
The track has also built a strong reputation outside Formula One. It has hosted DTM, Champ Car, WTCC/WTCR, NASCAR Euro Series, the 24 Hours of Zolder, and the Belgian Truck Grand Prix, which remains one of the circuit’s most prominent annual events.
What happened to the circuit after Formula One?
After the final Belgian Grand Prix at Zolder in 1984, the circuit remained active and continued evolving.
Its layout was altered several times, including major revisions in 1986 and again in 2002, producing the current 4.010 km Grand Prix circuit. Further safety changes were introduced in the 2000s, helping the venue host modern international series.
Zolder has also become notable as a multi-use sporting venue. In addition to motorsport, it has hosted major cycling events including the UCI Road World Championships, cyclo-cross, and BMX World Championships.
Circuit Zolder lap record
The official Formula One race lap record for the 1975–1985 Grand Prix circuit is 1:19.294, set by René Arnoux driving the Ferrari 126C4 during the 1984 Belgian Grand Prix.
Though Formula One no longer races there, Circuit Zolder remains one of Belgium’s most important permanent circuits — a track with a deep Grand Prix history and a continuing role in European motorsport.
