Hello, I have to be in Bern (Swiss) in the end of January for several months. So i thought of going from Greece there with the bike. Talking the ship to Ancona and from there through the highway to reach in 2 days Bern. That is something like 800km. My question is if this is possible during the Winter time with a Touring bike. I would like to see opinions from people who live in that region if there will be problems with frost, not allowing me such a trip. What do you think ? I do not plan to go through the Alps of course, as i said, the point is to reach safe there in 2 max 3 days. Thank you in advance.
