The poster explores the notion of Effort as an integral part of active mobility and in general of urban experience. Considering the increasing value of physical effort in urban life styles, we challenge the general premise of transport planning that tends to reduce the effort required for mobility - particularly when providing alternatives to car use. Informed by interviews we have conducted with inhabitants of three major agglomerations in Switzerland, Zurich, Geneva and Lausanne, we identify a threefold approach to effort, and explore the spatial implications of them for urban spaces that contribute to the practice of active mobil ity.
