I know when I shot my bull, I was at full draw for what seemed like forever....when my bow went off, the bull dropped, I was on all 4's trying to suck air....all that oxygen and I couldn't get any. It was the elevation for me. I thought I was in pretty good shape and I was, my muscles never fatigued however, oxygen was hard to come by...lol
For us flatlanders.
I have the same problem with elevation. My buddy has been bugging me to get back to the Rockies and hunt elk again. But, I'm getting to be more firm with the elevation restrictions. Nothing over about8,500 for me. Last time we spent the whole trip in the 11,000 range and it whipped my butt. Once you loose your breath up there, it takes about 5 minutes to get itback. Was in the best cardio shape of my life too. Problem is that there is no real way to train for elevation and lack of oxygen in any safe way except for spending a lot of time in the mountains. Some people are better equiped and not as sensitive then others though. Maybe I'lljust carry an oxygen mask next time.
