A question for some of you on here that have done SAS(R) Selection. What is it really like, fitness wise etc.? I do a lot of hill walking but do not like the running side of fitness. I can walk for hours in the hills with weight on my back and find it quite enjoyable, however, I find running very boring. What is the main type of fitness that is required during Selection> I'd be intersted to here from people who have experienced Selection, but please no walts who once knew someones 2nd cousins nexdoor neighbour who attempted it 10 years ago!
