Two years ago – in autumn of 2019 – I signed up for a 100km march in Vienna, that was supposed to be in April 2020, on the weekend of my birthday. As we all know, that minor thing called Covid happened in between, and thus this particular event did not. However, from this moment, the idea of walking around Vienna in one go was planted firmly in my head. Yesterday – Oct 23rd 2021 – it became a reality.
