Wierer and Vittozzi won't be competing in Oberhof, but Giacomel will be there. Vittozzi is clearly aiming for peak form in February and is giving up on the fight for the overall World Cup standings, while Wierer, at 35, has announced from the biggining of season, that she will be skipping some races.

Vittozzi- Wierer in 2019 or even some later. They are still not close friends and do not train together: Vittozzi has been training alone since last season, Wierer with the men's team for 4-5 years and the rest of the Italian team still separately - Vittozzi trained with this second group until she suffered an injury in the autumn of 2024.
So far, the Russians haven't even reached the Dnieper River, so don't worry. Poland has the same problem as Ukraine, in that there are no major geographical obstacles to the east: mountains, lakes, rivers, etc. The terrain is quite flat, but to reach Warsaw in a few days, the country would have to fall apart, the army would collapse and the authorities would have to escape from the country.
Probably 0% but in 1939 Germans reached the outskirts of Warsaw after only eight days (the border was more to the east than it is now i.e. they had less ground to cover). The ugly truth is NATO would most likely bide their time in response so the entire eastern Poland would be a battle field for a while.
