Jeff Zwart has just released a video of one of his shakedown runs prior to this year's Pikes Peak event.

The course is at the mountain in the middle of the California wilderness.

The 12-mile Pikes Peak course starts at 9 440 feet and ends at an altitude of 14 110 feet. Its 156 turns, mixture of asphalt and gravel surfaces and the sheer drops of up to 6 000 feet makeit one of the toughest challenges in motorsport.

Driving a Porsche 911 through this course is superb experience.

Enjoy the action in the video below.
