Four of them, and no two ask the same question. Every number below is measured off the geometry by a quasi-steady lap simulation — the same model that drives the car — not estimated.

Five fast corners you can see coming. Learn the whole game in four laps.
2.20 km, 5 corners, 4 laps — about 1:54 of racing. The reference lap is 28.45 s at an average of 261 km/h, topping out at 341 km/h and dropping to 153 km/h at its slowest point, a 62 m radius corner. Its three sectors are Approach, The Long Way, Home.
Seven kilometres of forest. Twenty corners, and an uphill left that decides the lap.
7.00 km, 20 corners, 2 laps — about 3:24 of racing. The reference lap is 102.11 s at an average of 234 km/h, topping out at 368 km/h and dropping to 94 km/h at its slowest point, a 20 m radius corner. Its three sectors are The Ascent, The Deep Woods, The Sprint Home.
The long one: eighteen corners and two enormous straights, twice round.
5.89 km, 18 corners, 2 laps — about 3:05 of racing. The reference lap is 92.57 s at an average of 217 km/h, topping out at 354 km/h and dropping to 96 km/h at its slowest point, a 20 m radius corner. Its three sectors are The Arena, The Old Loop, The Run Home.
Two lanes between the barriers, nineteen corners, nowhere to put a mistake.
3.55 km, 19 corners, 2 laps — about 2:24 of racing. The reference lap is 71.79 s at an average of 169 km/h, topping out at 311 km/h and dropping to 92 km/h at its slowest point, a 20 m radius corner. Its three sectors are The Climb, The Tunnel, The Harbour.
Fifteen corners through the container stacks, two of them hairpins.
0.98 km, 14 corners, 5 laps — about 2:25 of racing. The reference lap is 29.06 s at an average of 122 km/h, topping out at 166 km/h and dropping to 79 km/h at its slowest point, a 15 m radius corner. Its three sectors are The Stacks, The Long Side, The Crane Line.
Four legs folded between the stacks, and a hairpin at the end of each.
0.85 km, 12 corners, 6 laps — about 2:36 of racing. The reference lap is 25.93 s at an average of 118 km/h, topping out at 155 km/h and dropping to 78 km/h at its slowest point, a 15 m radius corner. Its three sectors are The Teeth, The Loop, The Gate.
Round the ring on the roof, then back down and underneath it.
1.31 km, 17 corners, 4 laps — about 2:35 of racing. The reference lap is 38.87 s at an average of 122 km/h, topping out at 201 km/h and dropping to 78 km/h at its slowest point, a 15 m radius corner. Its three sectors are The Roof, Underneath, The Ring.
The grid sits under the deck you will be racing on a minute later.
0.92 km, 9 corners, 6 laps — about 2:38 of racing. The reference lap is 26.40 s at an average of 125 km/h, topping out at 193 km/h and dropping to 78 km/h at its slowest point, a 13 m radius corner. Its three sectors are Under the Deck, The Climb, The Drop.
Three of the four are authored as curvature profiles: straights, and corners whose curvature ramps linearly in and out through a clothoid easement before settling. Real circuits are surveyed the same way, and it is why a Sliplap corner is something you squeeze into rather than flick at. Albion is the exception — it is traced off a real circuit's centreline and filtered along its arc length.
Each closes exactly: the arc angles are budgeted to sum to 360 degrees, and the residual position error is spread across the straights so no single straight is distorted.
