The worst thing for me about the Jungfrau Marathon is/was the stint on the Eiger Gletscher, just before the end. This is a piece of real estate that is narrow, steep, rocky and covered in scree, with an unhealthy drop on either side. So it beggars belief that I'm smiling in this photo. That goes to show how enjoyable the whole experience of taking part in the 2012 event was, when even the bad times were good.
