My Climbing Partner's Training Regimen

MY PARTNER in many adventures, John, approaches big endeavors with his own unique training style.  He likes to attack Mt. Whitney, round trip, in single one-day bursts, which he has accomplished tens of times.  Going from sea level to 14,500 feet, he prepares by a night of acclimatization at Lone Pine, 4000 feet. 
His annual training regimen for the L.A. Marathon is equally compact -- a couple of hours on the treadmill, a lunch break dash to the beach, some Pilates.  
I hope his training program for this very serious climb is somewhat more rigorous, seeing that I'm on the other end of the rope and we're leaving in a week.
