Have to be in decent health, and learn your way around the mountains. It can be very tough, but planning is key. Remember, you're not carrying all your stuff in on an atv. Everything you need to live and hunt up there is going to be on your back. Its a beautiful, different environment to hunt in. I wouldnt try it now, for health reasons, but I know a couple of guys my age (mid 60s) who still go. - dan
Being in good health and decent shape is a good place to start when hunting in the mountains.
But even if a person may not be in "sheep shape", they can have an excellent time and memorable experience hunting in the mountains.
I used to be in much better shape and health, and spent a bunch of time hunting in the mountains, and when time afforded made hikes in the hills to get in shape for those hunts. I also used to take the stairs instead of the elevator at work to work on conditioning.
The biggest thing is to be honest with yourself (and your guide or hunting partner) about your health and physical conditioning. Know your limits, and stay within it.
These days, I am not in the shape that I used to be in, and with a desk job that keeps me busy 10+ hours a day, by the time I get home and tend to daily chores, I spend more time sitting at the end of the day, just as physically exhausted from the mental stress of my day job.
But his does not stop me from mountain hunting even when I am not in "sheep shape".
I am built more for comfort at this stage of my life than I am for speed! LOL
The first lesson learned hunting in the mountains; Pace yourself! It really becomes a mental game! Perhaps even more than a physical one!
Just because your hunting partner can get to the top of the hill in one push, does not mean you have to. A good guide, or hunting partner, will work with you, while helping keep you motivated to get there. But this should not come at the price of your physical health and condition.
You win more by having an enjoyable adventure, whether you are successful in getting your game or not, and getting home safe and sound, with memories of the enjoyable hunt and shared experiences with friends old and new! While the challenges are great, and many of relish in having conquered them, it should not conquer us!
You need to arrive at the top, still in good enough physical state (muscles, mind, heart and lungs not exhausted and struggling to stabilize) to be able to hold your binos steady for glassing, or better yet, calm enough to steady your breathing and body, to hold your rifle steady for a shot at your target animal, should it be there within your comfortable shooting distance.
You may be able to shoot comfortably at the range from the bench or improvised field positions when you are relaxed and rested; but can you do this after climbing a few hundred feet in elevation when your muscles are trembling from exertion, and your heart rate and breathing rates are elevated?
During the climb, take your time. If needed, make shorter pushes and take more short rest periods of a few seconds or a few moments to catch your breath and keep your muscles, mind and breathing at a more controlled and relaxed level. You will find that you will actually reach your destination quicker and in better condition to make a shot than otherwise. Many worry that they will not get there in time for a shot before the animal is gone, and push harder because of this.
While this may be true, is it worth killing yourself to get there for an opportunity if you have a heart attack before getting there? Or get there and are not in good enough condition to take a shot? If the animal is gone, then you will have to keep pushing to find it again anyways. Hopefully you will still be able to keep pushing on instead of giving up because you are exhausted and cannot push on.
You will find that you require longer periods to rest and recoup by making longer, harder pushes, that will have you completely exhausted when you get to your destination, or worse that you will not be able to catch your breath and steady your heartbeat and breathing enough to be able to take a shot while the opportunity is there.
The other thing here that most do not think of or realize, is that when we are hurrying, tired and/or exhausted, we tend to become careless and take chances we shouldn't in steep, rough terrain, where you need to be mentally sharp to keep from taking a mis-step or unnecessary chance that could result in slip/trip/fall and distratrous injury (or worse). Know too many guides who had this happen to their hunters, or worse, had their hunters die of heart attacks on the mountain.
