The Games were full of contrasts. From a sporting perspective, the gentle gracefulness that I observed at the figure skating was offset by the full-on brutality of ice hockey brawls, while the delicate precision of curling was juxtaposed by the frantic chaos of short-track speed skating. From a geographical and cultural perspective, Livigno, which is perched high up in the Alps close to Switzerland, seemed like a giant playground for modern snow sports – geared towards those who like to twist and twirl high in the sky – while Cortina, in the Dolomites, was far more old-fashioned and populated by the traditional skiing establishment. Milan, meanwhile, featured a cluster of modernist, edge-of-town arenas, with international fans happily catching the metro to and from the events. But, in my experience, transportation wasn’t always so convenient. The huge amount of travelling between venues – I went to all but one – was exhausting and getting a late night bus over the mountains between Livigno and Bormio in a blizzard felt a bit hairy.
