Say you are Kipchoge and want to run unsupported marathons across the Appalachian Trail but need to carry 30 Pound of water and hear with you on a backpack. Could you comfortably run with that kind of load on your back without destroying what you are carrying from all the motion? Any one make a gyroscope stabilized backpack?
Yes its turtle hermit training
People do it all the time....in boots....with ACH and weapon....and military uniform.
My Air Assault ruck march was approx 35lb plus weapon and in boots and ACUs of course. Over 12mi I averaged a 10min mile. Fastest I've heard anyone of going it 1:38.

actually quite easy. Question is, for how far? A mile or two, sure. A marathon? pretty damn tough, unless it's a (relatively) light pack.
I once ran a 6:30 (think it was 6:38?) on a slight downhill with about 70lbs on my back- reason for the urgency was that it had taken me longer to fill water than expected, so my gf was a fair way in front of me and there had been an advisory about a grungy person acting strangely on the trail. Since I was carrying the sidearm, I was a bit worried about her being so far ahead and basically drilled it to catch up to her before it became totally dark (I was in roughly 16:30 shape at the time). Obviously the adrenaline can do plenty for you (along with the downhill) but that doesn't last long. Couldn't have done more than another mile like that, then I would have been spent.
Sure seems like 30lbs would be enough to limit you to double digit mile pace at best.
