I parted the hotel room curtains and looked out at the misty lake at the foot of the hill. I estimated that it must be five kilometres around, and Google Maps more or less confirmed this. I checked my watch, and double checked the train departure time, before pulling on my running shoes and heading out the door. The sun was still making its way slowly up from behind the Alps, the mist sat heavy on the water surface. Small rowboats and yachts bobbed gentle on the still waters. Apart from a lone fisherman and a handful of equally over enthusiastic early morning exercisers, I had the blissfully silent five kilometres all to myself.
