for all of you seasoned elk hunters what kind of physical shape would you all recommend me to be in to make my hunt more enjoyable and better chance for success I figure the better shape the better but I have to face the fact that I not a runner I cant run a half marathon like some people post on here can. guess what I am asking is there a rule of thumb what I should be able to do for instance run a mile or hike 5 miles with 30lbs on my back don't get me wrong I have been running hills trying every thing to get my legs and my lungs in better shape for about a month but I still cant run a half marathon knees wont hold up. guess I am getting a little worried that I am going to be hurting when I get to Colorado. If you guys could shoot me some opinions I would appreciate it thanks Oh yea I am in low elevation down here in Texas
