IFRL History
Jules de Thier and Henri Langlois van Ophem drew a triangle of public roads through the Ardennes in 1920. Motorcycles ran first, in 1921, because only one car entered the planned race. The 24 Hours of Spa began in 1924. Raidillon was built in 1939 to replace a slow hairpin at the old customs post; Eau Rouge is the iron-red stream under the track. The modern 7 km layout arrived in 1979. In 2000, Mika Häkkinen caught Michael Schumacher on the Kemmel Straight as they reached backmarker Ricardo Zonta; Schumacher went one side, Häkkinen took the other, and came out ahead. Magnificent judgment. Not a plan for eight friends at once.
Fun fact
Spa hosted the shortest race in Formula 1 history in 2021, stopped after two laps behind the safety car in torrential rain.
The corners that matter
La Source (1) is the first-lap hairpin: one apex, no mercy, brake early and pick a side. Eau Rouge and Raidillon (2 through 4) are one sequence, down, left, right, up, left at the top; flat in Gr.3 when dry and a conversation when wet. Do not send it two-wide. Les Combes (5 and 6) is the overtake at the end of Kemmel; time the tow so you’re not turning in through dirty air. Pouhon (10 and 11) is a double left at speed; sudden mid-corner corrections send you wide fast. Blanchimont is flat and serious. The Bus Stop (18 and 19) is the last pass and the last chance to throw it away. On lap one: La Source and Les Combes. In rain, the whole mountain.
Main-event strategy
Spa has rain, and here random weather is not flavor text, it’s the race. Thirty minutes can be dry, dry-wet, or a mess, and it can be raining at La Source while Pouhon stays dry. Dry: one stop on mediums. If rain is coming, pit for intermediates before the field discovers Eau Rouge is a river. The pit entry is on the right at the Bus Stop and its narrow approach costs time before service begins. Fuel at 6x on a 7 km lap is the real limiter; cars that sip and stay stable at Blanchimont win. Playoff pool applies; the Porsche 911 RSR, the Mercedes-AMG GT3, and the Nissan GT-R Nismo are the calm choices if they’re in it. A twitchy car lifts at Raidillon and loses the straight. The finale is 30 minutes. Finish it.
Garage notes
Low-medium downforce; Kemmel and Blanchimont reward speed, Sector 2 rewards grip, and the compromise decides the race. Gear for about 190 mph. Brake balance forward for La Source and the Bus Stop. Enough spring to survive the Raidillon compression without bottoming.
Opener notes
The F40 is the right car to close a season: mid-engine, turbo lag, and a chassis that tells the truth. On mediums it steps out of La Source if you hurry, and if the boost hits in the wrong gear at Raidillon you meet the runoff. Apply throttle progressively and short-shift to smooth the boost. Reverse grid at Spa is a gift to the patient: survive the hairpin, don’t send Eau Rouge two-wide, pass at Les Combes or the Bus Stop.
