Hello Ulf
Hei, velkommen til Sveits, velkommen til SBB-fellesskapet.
Please kindly note, the area you are going to visit is not served by SBB yet by RhB, the Rhaetian Railways.
With a valid event ticket, you benefit from free travel on
- the Postbus lines between Chur and Tiefencastel and the Biathlon Arena, as well as on
- the RhB line between Chur and Tiefencastel, in 2nd class.
This information is also given on the event’s website:

Let us know if you need more help.
Kind regards,
Roland
