On Friday, 4 July 1952, Hermann Buhl, leaves Innsbruck on his bicycle, rides up the Inn valley, after 150 kilometres arrives at the base of the north-east face of Pizzo Badile, climbs it solo the Cassin route, descends, gets back on his bicycle and returns home, to be at work on Monday morning. A famous feat, narrated in a few simple pages in the beautiful autobiographical book. Summer 2021. Maurizio Panseri and Marco Cardullo retrace the cycling and mountaineering itinerary of Hermann Buhl: for him the bicycle was a necessity and the means he had available to accomplish the feat, for ours it will be the means to rethink sport in a sustainable way. Maurizio and Marco's journey offers a framework for meetings with people who have linked their name to that of the mountains.
