TAIPEI (REUTERS) - A Polish mountain biker broke his own world record by cycling up 3,139 steps, which he accomlished at the Taipei 101 tower on Sunday.

Because the skyscraper did not have enough steps, Krystian Herba had to first cycle up to the 60th floor, and then take an elevator to the ground level before going up to the 91st floor to complete his record, which he said was allowed by Guinness World Records officials.

It took Herba two hours and 13 minutes to complete the challenge.

He is still waiting for confirmation of the new record by the Guinness authorities.

"I'm really tired, but I'm pretty happy. It was absolutely the most difficult and hardest challenge in my life," Herba said.

The 33-year-old physical education teacher surpassed his previous record of last year, when he climbed 2,919 steps in Melbourne's Eureka Tower.

According to a Polish representative in Taiwan, Herba had previously completed nine similar challenges, climbing some of the tallest buildings in the world.

Taipei 101, which is more than 500 metres tall, was formerly the tallest building in the world between 2004 and 2010, before the Burj Khalifa in Dubai took this title.
