>>2301507Depending on your constitution the major revelation might be that the process of mountaineering can be extremely strenious. And deadly. Because unlike when you're cycling or doing whatever, you can't just stop when you are tired. It gets dark early especially in winter and some people that can't get down are fucked. It is probably one of the most underestimated sports in terms of danger. I live close to the alps and there are people freezing to death in June on 8500 footers each year if it wouldn't be for mountain S&R because they can't into weather and they are still not on the peak at 3 p.m and keep climbing.
But the constitution is something that you can train so no, you are not fucked.
