Thomas Dold, of Stuttgart, finished in just 10 minutes and 16 seconds. Dold was grimacing in pain by the time he reached the top Tuesday, and he sprawled on the ground. He is now tied with two others for the record for the most wins in the event.
Women's winner Melissa Moon completed the run in just over 13 minutes. The 40-year-old from Wellington, New Zealand, ran with gloves on her hands to grip the railings.
When she finished, she smiled and said: "Oh, look at that view!"
The contestants began their mad dash in the lobby and finished on the observation deck. They had to jostle with others in a stairwell wide enough for only two people at a time.
