As mentioned earlier (with the wrong number of steps, now corrected), 600 climbed Beijing’s tallest building as part of the Vertical World Circuit. We prefer to call the building “World Trade Center 3”:

Germany’s Thomas Dold came first, sprinting up the 82 flights – and 2,041 steps – to the observation deck of the China World Summit Wing hotel in nine minutes 55 seconds.
The event was co-hosted by the Shangri-La hotels group and the International Skyrunning Federation.

The rankings of the tallest building in China is changing.
At 632 meters and 121 floors, the Shanghai Tower (Pudong district) is now the world’s second-tallest building.
When completed in 2014, the building will have retail and office space, and a luxury hotel. It was designed by the U.S. architectural firm Gensler. It replaces the Shanghai World Financial Center (completed in 2007) as China’s tallest building.
