The legendary French 'Spiderman' Alain Robert on Thursday (April 12) climbed Qatar's highest building - the Torch Doha - in 93 minutes and 47 seconds, claiming to achieve a new Guinness record.

The building is the highest ever to be ascended by a climber without a safety rope and harness.

Robert spoke to Reuters as he prepared for the climb and said he was both excited and scared.

"It can be different, you know, depending on the building. This one is quite complicated so... Actually there is excitement but there is also a bit of fear which is very normal," he said.

Robert's actions - often illegal - have repeatedly landed him in jail.

"I have been in jail many times, a lot in the US, but also in China, in Malaysia, in Japan, in Australia. But I am used to it, you know for me it is quite interesting actually, it's not that bad. I am not seen as criminal, not as a bad one for sure. It is just, you know, a different way of living," he said.

Robert has scaled over 85 giant structures around the globe, most of which he has ascended using only his bare hands and climbing shoes.

Well-known for climbing unassisted, the 50-year-old has conquered more than 70 skyscrapers - pioneering attempts of such kind including the Empire State Building, Chicago's Willis Tower, and the Petronas Towers in Kuala Lumpur and Burj Khalifa, the world tallest building in Dubai.
