“The World’s Longest Staircase Is in Switzerland”
In 1910, a funicular railway was completed from the village of Mülenen up to the peak [of Mount Niesen in the Swiss Alps]. . . .
But more interesting than the funicular, in my opinion, is what runs up the mountain right alongside it: a two-mile staircase with a slope that gets up to a glute-grinding 65-percent gradient. There are a world record 11,674 steps up the mountainside—enough steps to climb the Burj Khalifa skyscraper in Dubai four times, and enough to climb the Statue of Liberty 33 times.
For safety reasons, the stairs are just used for maintenance and not open to the public. But once a year, 500 lucky participants get to tackle the world’s longest staircase climb, the Niesen Treppenlauf. . . . And the record for running up the equivalent of seven Empire State Buildings? A remarkable one hour and two minutes.
