MCD2021, I am someone currently on hormone therapy. I don't recall any real problems with the bicalutimide and just like your partner it was only for a short period either side of my first Zoladex injection.
On Zoladex while waiting for radiotherapy (which got delayed for various reasons, but should start in the next few weeks) I have so far been on three skiing holidays and one cycling/tourism holiday with no problems. (You may tell, after all the issues of Covid we are taking what opportunities we can to have fun while we are able to).
No problems with those.
