Running in the Swiss Alps

This weekend there is an ultra trail in the mountains of Switzerland , the Eiger Ultra. One year ago I participated in the first edition and ran the E51. At some points the snow was not gone and it took some effort to navigate through it. Now other people are looking forward to their adventure, running in the stunning scenery of the mountains around Grindelwald. I am a bit jealous, but I will take of to Sweden for my own adventure.
