I just try to get to a point where a 10 mile run is pretty casual (just meaning I’m not super sore the next day) and hit the one hill my city had at least once a week with a 50 lb pack, walk up and down until I hit 1k vertical each way. I also lift a few times a week but that’s just because I enjoy it. I personally feel like a lack of volume is the most likely thing to bite you on a hunt (for example Achilles killing you by the third day because you’re putting in way more mileage than you’re used to and aggravating ligaments).
