The Stair race takes place in ‘De Rotterdam’. De Rotterdam is a building on the Wilhelmina pier in Rotterdam. The 44 storeys have a total surface area of approximately 160,000 m², making this one of the largest buildings in the Netherlands. Every year, several stair races are held worldwide, where competitors climb the stairs of the world’s most famous buildings, such as the Empire State Building. It is a grueling sport in which your whole body weight has to move both horizontally and vertically.
