On the afternoon of the 21st of February, Varsovians take part in the tenth edition of the Everest Run, a 24-hour fun run up the stairs of the Skyliner tower in the centre of Warsaw. Runners may complete as many climbs as they wish; however, the goal is to reach the 42nd floor 52 times, reaching the height of Mount Everest. The event lasts 24 hours, and runners can take breaks at any time. They may even go home to sleep before returning, reinvigorated, to attack the peak. This year, a runner named Klaudia Krajewska ranked highest, completing 109 climbs, stopping a remarkable one climb of the tower from ascending Everest twice.
