Ok, first just a short introduction:
I'm 27 years old guy from Finland. I became a semi-paleo-eater 
without knowing, having given up grain and milk products by and 
large, and then coming a cross this article about paleo in a
finnish newspaper. I'm 195cm tall (6 feet 7 inches?) and was 
110 kg after christmas, my fat percentage was around 21. 
Now I'm 102 kg and an all-paleo-eater, happily so. DGF is a
vegetarian, so we're a "tough crowd" to invite for a dinner <g>.

Hobbies include golf, horsebackriding (dressage and equestrian), 
rock-climbing and mountaineering. I'm now starting gym (again) 
also.

The problem i see is that mountaineering for me is a very 
seasonal sport, because it's usually just for one month 
intensively on mountains and the rest of the year i do my 
other hobbies. So trying different variations is difficult.
 
I used to load up on carbs, fat and protein the evening before, 
and then "drink my way up", maybe with a few energy bars. Then 
cooking some pasta etc. on the way down. 

Usually I do two or three consecutive days of hard climbing 
followed by one or two days of rest (only light to moderate hiking, or 
none). This goes on for 3 to 4 weeks in a row. 
At least my vital capacity is high after that <g>.
