Very interesting thread. Enjoyed very much the whole reading

. I dont know so much about the TV show and dont watch much TV anyway

. The only real experience I have about something similar, it dates back more than 20 years ago, during my compulsory (at that time) military service. I was serving in Alpine Troops, as a rifleman. The most feared mandatory training for recruits was this Winter Camp. It was nick-named la settimana bianca (winter ski holidays) but it was quite the opposite of a Club Med vacation

. The platoon was out for one week in the Alps woods in January. Average temperatures ranged from -15°C to +5°C. The whole training was about marching for kilometers in deep snow with snowshoes and the military version of cross country skis

, setting down the machine-guns and mortars, taking posts, shooting targets, dig kind of trenches in the snow, take up machine guns and mortars, marching, setting up shelters for the night, waking up from explosions, etc. Eating only MRE with no possibility to light up proper fires. Basically it was sleeping privation and exhaustion training. Clothing soon got wet with no possibility to proper dry them and we were shivering most of the day, unless moving. The backpack was weighting like a truck on my shoulders. Even pissing was a chore, specially during the nights

. Several guys had to withdrawn due to principles of hypothermia and principles of trench foot and frostbites. At that time, the gear for the non-professional Army was rather low-quality. Some guys injured themselves (not seriously), some just broke down emotionally. In the mornings, if we were not woken up by mock explosions (and therefore jump ready to respond sham enemy fire) there was the exercise to field strip, clean and re-assemble the AR Beretta 70/90. I can tell you, in the cold wind raging, with half frozen hands, with no sleep, little food, exhaustion and fatigue, even this rather simple operation it was a chore. Of course we were 19-21 years old bunch and medical staff was always around

. Never experienced anything that extreme afterwards, in my civilian life.
I dont know
In principle I recognize the good of trainings like this, on the other hand I ask myself why (besides the 500.000 $ prize going to the competition winner in TV show

). I mean, one thing is to keep fit (I run three times per week, MTB when I can, do some cross-fit training, etc.), to practice some skills (I try to be out in the woods or at sea when I can) but seriously
why shall I put myself in such chores and dangers? Why, at this point of my life Id need to train for exhaustion. Train to know how you will operate when you're miserable, and when laying down to die starts to seem like the more desired alternative? I know already I will operate miserably

. For me hiking and camping out its just a relaxing activity and a sound and healthy way to spend time with my family. In my areas also, the possibility of getting lost in the woods, mountains, etc. is very, very little. Theres no real wilderness. Mountains are populated by villagers, hikers, ranchers, fishermen, campers, skiers, etc. We go travelled tracks, marked trails. Cell phones are always working and now, out of five members in the family, at least four have their own one

. Mountains huts and bivouacs are mostly always manned. Unless one really want to play it extreme and climb glaciers or do some crazy off-piste skiing you are rarely in real danger situations.
About being alone, I dont know. Most of the times I appreciate being out alone. Maybe because it happens to me very rarely now. Alone in the woods, on a mountain peak, by myself. I think few things in life are more rewarding. I am just by myself, into the nature. Its a sort of prayer, I come to think about the mighty and the beauty of the world and the meaning of my hike on Earth and the sound of my footsteps on the dry leaves or on the rocks its a kind of melody . As I said somewhere else, I always have a positive feeling, a feeling of benign presences in nature. Sure I have to behave, not taking unnecessary risks, be prudent and careful but thats it. I dont feel I have any challenge with nature, rather, sometimes, a challenge with myself and my limits. But surely not to the extent of running routinely such training exercises
