Since October 2011 I have walked an identical route in Cologne. Whilst looking for a parallel route I found this one, both routes share their beginnings and ends as well as their distance: 3.5 km (by auto) between a world heritage building and a small shop in a local neighbourhood. What is there in between? What can happen in between? When in Cologne I walk the 5565 strides on a good day or 6275 strides on a tired day. When home I try to recall places I saw on the Beijing route when I first walked it and I draw the routes to find their gestural expression.
