Back on track. I've done it a few times and it's a ball buster if you get 1. The last Elk I packed out by myself was 4.5 miles away from my truck. Most of the journey was downhill but that's harder on your knees than going up hill. It's no picnic and you have to have a saftey plan just in case. The personal GPS thing and a topo map and compass are must tools when going by yourself.

Getting into shape is a great idea but don't kid yourself there is nothing you can do for the lack of oxygen you are going to experiance at 10,000 ft. Don't let it scare you just be prepared for it. Good Luck
