Weekend Warrior Syndrome

In my preparation for Gasherbrum 2 I put in a lot of physical work this weekend:

Friday: morning and afternoon runs of about 5 miles each. (Simulating effort camp 1-2 and 2-3)

Saturday: after two hours of sleep, 4 hour drive north and 8 hours on Mt. Washington including an hour on the top waiting for my friends to catch up and a 25-30 pound backpack. A 4 hour drive back to Worcester and 4.5 miles of running Saturday night on the track in a attempt to do a scheduled 10k workout. (Simulating summit day)

Sunday: 10.5 hours sleep then a 1:56 run of 16 miles in length simulating the descent on tired legs to BC. 

Now I know that in reality that no 5 mile run in Worcester will compare to hiking between 6400 and 7000 meters on the side of a mountain carrying all the stuff I need to camp and summit day. The same unreality goes for summit day compared to Mt. Washington and a run but I think that it's got to be somewhat close. Maybe 70% of the effort that will be required, of course that doesn't factor in the fact of me sleeping in my own bed at 900 feet above sea level. Or all the work before that point that might wear me down a little.  Am I ready? The only way to know is to try it.
