A Polish cyclist broke his own record in the Guinness Book of World Records by climbing a 492-metre-high Shanghai skyscraper by cycling on a bike with no saddle. Another remarkable aspect of the feat was that Krystian Herba, the Polish extreme athlete, climbed 100 floors and 2,754 stairs by not touching the ground with his feet or arms even once.

During his ascent, one member of his team tracked his climb with a camera on his head for documentation, and the other member of his team looked after his physical conditioning, providing water to fight exhaustion and keep track of the time. Herba said he would send the video and other materials to get it verified by the Guinness Book of World Record, once he reached Poland.

Herba, who has pursued the unusual hobby since 1995, said his motivation is "the strength, desire to strive for something, to be better, faster, to overcome not only another record but also weaknesses".

He completed climbing the 474-metre high observatory of the Shanghai World Financial Centre in one hour, 21 minutes and 51 seconds, thereby rewriting the world record he previously owned when he climbed 2,040 steps of the 72-storey Rose Tower in Dubai in January 2012.

He climbed the 72 floors in the world's tallest hotel then in one hour, 13 minutes and 14 seconds. Rose Tower in Dubai, which stands 333-metres tall, held the distinction of being the tallest hotel in the world between 2009 and 11 November, 2012.

This was the eighth skyscraper Herba had climbed, and has vowed to break records by challenging himself to climb the tallest buildings in the world.

"It is like asking a Himalayan climber why he is going to the mountains if he can simply stay at home," said the Polish acrobat, who is a physical teacher by profession.
