Next Sunday some top athletes from different countries will gather in the Lion City Singapore to run the Swissotel Vertical Marathon. For the very first time I will be participating there, well prepared, racing up the 73 stories as quickly as possible. Until 1986, the Swissotel was the tallest hotel in the world. Singapore is island and city state and because of its size the smallest state in Southeast Asia. Currently, 5.4 million people live there.
