The Watkins Glen circuit in New York State offers two track combinations: a Full 5,423 metres and one, known as the Inner Loop, of 3,895 metres.The Inner Loop, except for a chicane before the 'The Loop' hairpin bend, is practically the same as the Formula 1 Grand Prix track of the sixties and seventies. The new part of the track is characterised by four corners and a short straight. The Glen is a circuit that deserves respect because it is a really tough test for the drivers. Its high-speed 'esses' and its technical features make for an exciting drive. The 'esse' just after the first corner is a very challenging point, where the driver has to find the best trajectory for a fast exit onto the following straight that leads to The Loop.This is made harder by the slight climb along which the 'esse' winds, which drains power from the engines. The drivers also get to show their class on the final very technical part of the track, with its 90° curve.
