I don’t really think about it or worry about it much these days. I Strength train 3x a week, Mtn bike 3-4 days a week between May and hunting season and do a couple of weekends scouting before first rifle. Then I show up and do it. Living and playing in the mountains regularly, the pack out is really the only significant stressor if a properly planned hunt.
That being said, if you’re coming from low elevation, the altitude is a big smack and a long, multi day drive can you leave you in less than peak shape, so I’d probably taper a week out. At that point, there’s no real benefit to having significantly stressful training events. If anything, a couple of shorter sessions that leave you feeling confident about the shape you are in following the weeks/months (and your entire life’s worth) of training background has prepared you for. If you’re not ready for a Backcountry Hunt a week out, then you won’t be ready anyway. It’s more akin to being in shape for a Mtn climbing expedition where performance is spread out over days/weeks rather than the strategy of peaking for a single day like a race or competition on an exact day or 2-3 day window stage race etc. The only thing thing on the line is how much your preparation, or lack thereof, will allow you to enjoy Your trip and that preparation was determined weeks/months even years before your trip so killing yourself in one workout 3 days out will contribute nothing.
