I have hated about 99% of the threads you make. But this one seems like something worthy of a thread so I will contribute some advice.
If you're going to be climbing train your self for that. Go out bouldering or wall climbing for 2-3 hours every other day. Climbing gets easier the better your strength to weight ratio is, so throw some cardio in there. Perhaps bike from your house to the nearest climbing area, or fill a back pack with rocks and hike into the climbing areas. Then practice climbing for a few hours (Technique will get you miles further than strength when you're climbing, so work on learning the techniques first and gradually work your way up to combining strength and technique in hard routes) then head back home with your rock pack.
Try and do cardio 5-6 days a week, but remember to change it up, some days go hiking, some days go biking, some days try swimming laps. (I would count the hike in to climbing areas as some cardio, but you may wish to add some extra distance for better results)
The biggest thing hands down though is diet. The food you put in your body becomes the energy your body burns. Try to eat small to mid-sized meals and have 2-3 smaller snacks per day (Healthy stuff, such as: smoothies, fruit, nuts, trail mix, clif bars, ect...) Drink LOTS of water and stay well away from sodas. If I am going off for a big excursion I usually buy a gatorade and mix it 50/50 with water, it lasts longer and wont make you thirsty after drinking it.
If you're too lazy to read all of this heres some handy spark notes:
-Fill a back pack with rocks, hike into climbing areas 3-4 days a week, aim to climb for 2-3 hours, hike home with your rock pack. (strength, some cardio training)
-Cardio, cardio, cardio! Do cardio 2-4 hours a day 5-6 days a week. Try to change it up to keep it exciting, go biking, swimming, hiking, running, ect... any thing that gets your heart rate up and keeps it there.
-Diet, cut out chocolate bars, sodas, fried foods, fast food. Substitute those with healthy foods such as whole wheat pasta, fish, chicken, turkey, beans, ect... Remember to eat smaller portions for the 3 big meals (breakfast, lunch, dinner) and include 2-3 healthy snacks per day (fruit is a really good one, as well as nuts/trail mix, clif bars, ect...)
-Drink lots of water!
