I came in Zurich since Sunday to visit my sister living here last two years. The place is amazing. The weather is cold, but really afordable. We plan to visit a Ski Center during the weekend, while i will be working till Wednesday and try to maintain some parts of my training schedule during the week. Some time off is never bad, but really going back to zero, for a whole week is not a good idea.
Here is the lake in Zurich which is pretty amazing and cold currently:
