The maximum speed limit in New Hampshire is 65 mph, but that didn't stop Travis Pastrana from driving the full length of the Mt. Washington Auto Road at an average speed of 72 mph on September 9th, breaking a 12-year old record in the process.

Piloting a specially-prepared Subaru WRX STI performance car, the 4-time American rally champion and extreme sports star covered the historic 7.6-mile mix of asphalt and gravel in 6 minutes 20.47 seconds, 20 seconds faster than the previous record holder, Frank Sprongl, did in 1998.

Technically a test session in advance of next year's Climb to the Clouds Hillclimb competition - the first to be held on the private road in over a decade - the attempt was timed and confirmed by officials from RallyCar, the sport's top sanctioning body in the United States.

Pastrana was a fair bit quicker than the winner of the first Climb to the Clouds event held in 1904, who made it to the 6,288 foot summit in the then blistering time of 24 minutes 37 seconds.
