I've got roughly 52 miles and 22K+ vert total training in this season hauling roughly what I will be going into the hills with 40-65lb, occasionally heavier. Packed 63# vertical, 2.4 miles @ 3200ft gain.
I've done 115-140lb in the field, it wasn't fun, but all back to base camp.
Terrain has a lot to do with it, training, mindset. It all sucks...but it sucks a little less the more you do it.
You Anc and Wasilla guys have the best training ground on earth, really enjoyed my summer down there with all the hiking available!
I feel like you would find that actual pack weights are far from the estimated weight. I typicall try and take a front and rear each trip and then meat ans head the final trip, this all depends on distance, terrain, weather.....not sure what it weighs because I never check it. For me I don't notice much difference from 60-75ish lbs and then after that it all feels heavy. Practice loading your pack and doing some loaded training hikes to give you and idea of what you are capable off and then come hunting season load it up and keep putting one foot in front of the other.
Keep in mind that these are internet numbers you're referencing.
Here's the funny thing.......does anyone here have a 100lb girlfriend or wife? Most people would consider those to be ultralightweight and you can easily throw her over your back or shoulders and carry her without issue. But 100lbs of meat lashed tightly to a stiff frame that is positioned well with the load across your hips and shoulders is a problem?????
