Another endurance classic awaits sim racers as part of the iRacing Special Events calendar: This weekend, the Spa 24 Hours are scheduled to challenge racers twice around the clock at the legendary Belgian circuit. Here are the key facts for the event taking place from July 21st to 23rd.

24-hour races are always a special challenge, and Spa-Francorchamps has its special quirks that make it a bit different from other events of this kind. The 7-kilometer layout has a reputation for being a true driver's track, featuring the iconic Eau Rouge/Raidillon combination as well as fast sweepers like Pouhon (officially called Double Gauche today), Blanchimont or Stavelot that pilots need to master. iRacing's layout does not differ from the current-day one, but the circuit's surroundings are based on an older version.

As the grids tend to be quite large for the event (70 cars took the green flag in the real 2023 event), Spa's pit lane arrangements for the 24 Hours are unusual: The circuit has two pit lanes including garages available, one being the main pit building at the start/finish straight as used by Formula One and others, plus the old pit lane after La Source where the original start/finish area used to be. Both pit lanes are combined for the event, meaning pit stops take much longer than elswhere due to the long time cars have to spent cruising with the pit limiter on from entry to exit.
Another unusual feature is related to this: The timing line is located at the modern start/finish straight before La Source, which is where the checkered flag will also fly at the end - the start, however, is taken on the straight before Eau Rouge and Raidillon.

The Track
Spa is one of the most popular tracks in sim racing, and coupled with the circuit's rich history, it hardly needs an introduction. Located in the Ardennes, the layout created in 1979 - after the old, fearsome 14-kilometer high speed track was unsurprisingly deemed unsafe - follows the terrain and features exciting elevation changes as a result, most notably at Eau Rouge and Raidillon.Spa-Francorchamps in its 24-hour race configuration, using both pit lanes available at the track.

The Cars
Unlike the Nürburgring 24 Hours, the Spa Special Event is a GT3-exclusive race, just like its real counterpart. As a result, the in-class selection of cars available is much larger, as a total of nine GT3 machines are eligible to compete. Grids are limited to 50 entries per split, with two to 16 drivers per car allowed.- Audi R8 LMS GT3
- BMW M4 GT3
- Ferrari 488 GT3 Evo 2020
