Swiss tightrope artist Freddy Nock used neither a balancing pole or a security harness as he scaled a two inch thick cable to the top of the near 10,000 foot high Zugspitze mountain in southern Bavaria.
It took Nock an hour and 20 minutes to travel along the 3,000 foot long cable and he now plans to submit his feat for entry in the Guinness Book of Records as the "longest and highest wire walk above sea level without a balancing pole".
In the coming week, at different locations in Austria and Switzerland, he will also attempt the longest cable crossing with a bike and try walking the longest and highest rope down a valley.
He said: "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 kilometres wide which in the highest mountain area, in the Jungfrauenjoch in Switzerland that is more than 3,800 metres high, higher than this one.
"Can I get across that in the air? Or cycling with a bicycle across a tight rope over 120 metres at a height of 50 metres. Those are the things I do want to do."
