Walking or hiking longdistances is hard work. Most people, accustomed to a desk job and comfy couch at home, would be hard pressed to hike 10 miles a day unencumbered, much less 25 miles or more a day while carrying a pack weighing 40lbs or more.
This is part of the reason why it’s SO incredibly important to stay in shape. Even walking 1-2 miles a day does wonders for your body. Up that to a short 3-mile run 5-days a week and you’ll be far ahead of all the other desk jockeys whose life consists of sitting on the couch at home when they are not parked at a desk at work.
If faced with a situation where you have to evacuate an area on foot, even assuming that you aren’t carrying a pack or bug out bag, the physical toll can be dramatic if you are not in shape. This becomes even more pertinent when trekking cross-country through rough terrain or thick foliage.
The long and the short of it is that if you are preparing by stocking up on certain supplies and NOT preparing your body at the same time, you are doing yourself a disservice. All the gear in the world cannot save you if you are not capable of walking a few miles without collapsing to the ground like a beached manatee. Prepare your body with the same vigilance you prepare your supplies. Best of all: preparing your body by staying in shape is FREE!
