I have a NM turkey trip and San Juan backpack hunt under my belt (this year). I’ll agree with everything already said - it’s the elevation that really drags you down for a couple of days. If you’re in decent shape - you’ll get winded, but you’ll be fine. I felt like I moved overall faster if I went at a slow enough pace uphill to not max out you heart rate. Once you max out, it feels like you’re chest is constructed and it takes forever to get your breath back.
If you’re in excellent shape you’ll still get winded, but you’ll be able to go a little faster and probably have the confidence to go farther. In theory anyway, I fall into the “decent shape” category.
I’m convinced there is no way for a flat lander to fully prepare for the mountains. You just can’t simulate the altitude and terrain.
My takeaway is this - you won’t be as prepared/in shape as dudes that live out there and train in the mountains year round. That said, you’ll be able to do it and you’ll feel tired, but great after your hunt.
PS - cardio, weighted box step ups and trekking poles are your friends.
