(DUBAI, UNITED ARAB EMIRATES ) French "Spiderman" climber Alain Robert began scaling Burj Khalifa on Monday (March 28), his 128th known ascent to date.
As the sun began to set in the skyscraper metropolis -- Dubai -- Robert, sporting a pair of brightly coloured orange trousers, started his delayed climb.
Using ropes and a harness, the daredevil started to pull his way up the side of the world's highest tower, which stands at a staggering height of over 2,700 feet.
Although the Frenchman has climbed the likes of the Eiffel Tower in Paris, Malaysia's Petronas Towers and China's tallest building, he said that the gleaming Burj Khalifa as his greatest challenge yet.
"Actually there is huge pressure on me because I know that they have installed everything there; this is for me. There is a giant screen; 50 metres (164 feet) high, 30 metres (98 feet) long. I know everybody is going to look at me so it's a bit of -- a lot of -- stress in fact," said Robert in an interview with Reuters Television.
Unlike his previous international climbs, to adhere to the event organisers' regulations, Robert had to use ropes for security purposes, something he didn't object to.
"I know that sometimes there may be some specific requirements. I do understand! You know, this is such an iconic building so I can understand that even though they are taking care so much about my precious life, they are also taking care a lot of that precious Burj Khalifa."
As the 48-year old shimmied his way up the glass-fronted building, large crowds craned their necks skyward to catch a glimpse of the shaggy haired climber.
Speaking before his climb, Robert told Reuters that he will continue his adventures as long as he enjoys doing them:
"Life is made to be something funny, something that whenever I wake up in the morning, I think that I will enjoy the day because that's life."
Robert's manager, Bryan Yeubrey, said that he expected the climb to end by 1930GMT on Monday.
