The crossfit, wt. training, running etc is necessary for both conditioning, strength and injury prevention, but some of your training needs to be what you do when you hunt and that means packing heavy loads. So start increasing the wt. of your pack load during your weekend hikes.
Yeah, I forgot to add that towards the end of summer start swapping runs for ruck marches. The US Army Rangers used to do one longish ruck march each week, they decided that was enough with their other PT. Guys getting ready for SFAS typically ruck march 3-days/wk. Definetely no more than that. Two middle distance and maybe one longish ruck each week, max.
