My hunting partner (who is a rookie and I'm not much better) thinks we can backpack in about 6 miles in a couple hours. I think he's nuts! #1 we are both flatlands,live at 1200 feet. Both in good shape but you can't train for lack of oxygen. I'm thinking its going to be at least 3-3 1/2 hours. Its mostly a gradual climb where we are going but also a couple creek crossings. Still it's all uphill, probally gaining1500-1800 feet total before we camp. What's your opinion on how fast you typically can travel with 60 lbs of gear on your back?
