🏁 iRacing 2026 Special Events Calendar
Spa has hosted a 24-hour endurance race since 1923. The real-world event is part of the Intercontinental GT Challenge, and iRacing has had it on the special events calendar since 2016. This year’s event carries Falken Tyre sponsorship, a brand with long roots in endurance motorsport. The iRacing version replicates the weekend atmosphere closely, including night stints that send you through Raidillon and the long Kemmel Straight in near-darkness. Those sections are demanding under any conditions. However, at 3 AM in the rain, 16 hours into a shared stint, they become something else entirely.
The 2026 event is single-class GT3. Every car on track competes for the same positions, which keeps the racing cleaner than multi-class events elsewhere on the calendar. The full GT3 grid is eligible: the Aston Martin Vantage GT3 EVO, Acura NSX GT3 Evo 22, Audi R8 LMS EVO II GT3, BMW M4 GT3 EVO, Chevrolet Corvette Z06 GT3.R, Ferrari 296 GT3, Ford Mustang GT3, Lamborghini Huracán GT3 EVO, McLaren 720S GT3 EVO, Mercedes-AMG GT3 2020, and Porsche 911 GT3 R (992). Balance of Performance is applied across the grid, so car choice comes down to familiarity rather than any outright speed advantage one model holds over another.
If you’re unsure which GT3 to pick, drive the one you’ve spent the most time in. Twenty-four hours is long enough that comfort and confidence at the limit matter more than a small BoP edge. Because the racing is single-class, you’ll be fighting the same cars from flag to flag, so setup consistency and pace management matter far more than peak qualifying speed.
Teams require between two and five drivers, with fair share rules in place. Each driver must complete a minimum share of the total race time, so your stint schedule needs to account for that before the race starts. You can’t build strategy around keeping your fastest driver in for the first six hours and filling the rest with symbolic stints. Four time slots run across the weekend, giving drivers in different time zones a realistic window to enter. Splits are determined by iRating, so teams are grouped by competitive level. Registration is handled through the iRacing member UI. If you haven’t confirmed your team and car, check now.
Twenty-four hours of GT3 racing at Spa is not something you improvise on the day. The teams that do well are prepared before the green flag. Start with stint planning: work out how many drivers you have, what fair share requires from each, and structure stints around the fuel window for your chosen car. Most GT3 cars at Spa require pit stops that don’t align perfectly with ideal stint lengths, so plan the compromise in advance rather than sorting it out under pressure in the pit lane.
Tire management is central to Spa’s difficulty. The circuit puts significant load through Pouhon and the Bus Stop chicane, and GT3 tires degrade quickly when drivers push too hard early in a stint. Therefore, build your pace around the tire, not the other way around. Drivers who charge from lap one typically find themselves managing degraded handling well before the stint is done.
Pit stop execution is where 24-hour races are won and lost. The teams that win rarely hold the fastest raw pace. Instead, they’re the teams that avoid traffic at critical moments, execute clean in-laps, and don’t lose positions through slow or mistimed stops. Practice your pit stops before the race. Additionally, the weather system at Spa can shift conditions dramatically over a 24-hour period, particularly during the night window, so have a wet-weather setup ready for your car before you queue for your first slot.
