Freddy Nock, Stuntman, Walks Tightrope To German Mountaintop (PHOTOS)

A 46-year-old Swiss stuntman has ascended a nearly 10,000-foot-high mountain by tightrope walking a two-inch-wide cable car wire—without the aid of any safety gear.

Freddy Nock clambered up the cable to the top of Bavaria's Zugspitze mountain with so little as a balancing pole. It took the daredevil less than 90 minutes to make the ascent, which is the longest and highest wire-walk in history, the Daily Mail reports.

Nock has an even more daring stunt planned for later this month: He'll ride a bike across a wire in an effort to raise funds for Unicef, reports The Telegraph.

"I will attempt seven records during this week. It has everything, incline, to walk down a cable car, walk across a lake that is more than three kilometers, which in the highest mountain area, in the Jungfraujoch in Switzerland, that is more than 3,800 meters high, higher than this one," Nock told the Telegraph.

CORRECTION: This story previously described Zugspitze as a mountain in Switzerland. The mountain is, in fact, in Germany.
