History
The 20-turn course, which features an elevation change of 133 feet, runs counterclockwise. It begins with a steep uphill climb into the iconic Turn 1, nicknamed “Big Red,” which finishes with a hairpin left turn. The field then descends from the Turn 1 hill to navigate a series of fast sweeping esses in Turns 3-6 into a blind corner at Turn 10, taking them to the far end of the circuit and another hairpin at Turn 11.

The course then offers a more than half-mile straightaway back towards the pit and paddock area before entering the final technical section of the track where drivers will weave through a series of corner turns in 12-15. That section is followed by a downhill, multi-apex corner with limited run-off before the final two corners of the circuit, a pair of left-hand bends that return the field to the main straightaway.
