Getting fit for a mountain hunt

Our camp sits at 8,900 feet, and the basins in Unit 214 go above 10,000 (sample). Thin air and steep ground tire everyone, whatever their age.
Start eight weeks before your hunt: walk hills three times a week with a pack, adding a little weight each week. Wear the boots you will hunt in.
Tell your guide about knees, hearts and lungs. We would rather plan an easier route than turn back at midday.
