The St. Petersburg Grand Prix joins iRacing in Season 2 as a single-configuration street circuit. As a real-world street course built on temporary roads around a municipal airport, there’s no alternate layout available. What you get is the full 1.808-mile, 14-turn circuit used for the INDYCAR Grand Prix of St. Petersburg, and nothing else. Here’s what that means for how it appears in iRacing, which series use it, and who should consider buying it.
The Configuration
St. Petersburg runs one configuration in iRacing: the full 1.808-mile layout. There are no short infield variants, no alternate routing, and no oval configuration. Street circuits are defined by their temporary nature — the track exists for one week a year and then disappears back into public streets. You can’t add a chicane or run a shorter version of a public road network. The full Grand Prix circuit is what exists. It’s the only option.
The layout includes Albert Whitted Airport’s main runway as the start-finish straight, sections of 1st Street SW and Bayshore Drive SE through the downtown waterfront area, and 14 corners ranging from a tight first-corner chicane through a demanding technical complex to a pair of sweeping final right-handers. The lap is 1.808 miles at its full length, and that’s the only way to experience it in iRacing.
Which Series Race Here
St. Petersburg is available for use across iRacing’s road racing ecosystem. In official iRacing series, it appears on the schedules of series that run open-wheel, sports car, and touring car content. Street circuits like St. Pete work well with INDYCAR content like the Dallara IR18 and IL-15, with GT3 and GTE cars, and with TCR-class touring cars. The tight walls and unforgiving nature of the circuit reward clean driving, which makes it well-suited to series that already put a premium on avoiding contact.
In hosted sessions and leagues, you’ll find St. Pete used across a wide range of car classes. The track works with almost anything that runs on a road course, though the tight chicane at Turn 1 and the demanding Turns 4-9 complex make it better suited to cars with good mechanical grip and responsive braking than to high-powered prototypes that struggle with slow-speed traction.
Who Should Buy It
If you run any kind of road racing in iRacing and particularly if you follow INDYCAR in real life, St. Petersburg is worth having. It’s a genuinely demanding street circuit that produces interesting racing and is unlike most of the road courses in the iRacing library. The airport straight gives you a genuine long-run braking point, the downtown section through Turns 4-9 is technically complex in a way that separates drivers who’ve learned the track from those who haven’t, and the wall-lined nature of the circuit means there’s real consequence for mistakes.
The track arrived in Season 2 with AI Racing enabled from day one, so solo practice against AI opposition is available immediately. If you run INDYCAR content or open-wheel racing generally, St. Pete should be on your list.
