>>1379196Depends on a lot of factors, namely being how much food weight you can tolerate carrying and what percentage of your total pack weight is food weight.
When I was younger, dumber, and poorer I could hump an 80lb pack for a couple weeks because it was either do that or don't go (couldn't afford lighter gear; couldn't afford to arrange resupply points ahead of time). Managed to sustain myself, at the longest, 23 days on the trail. But that was good weather and relatively easy hiking (no more than ~1000ft elevation change in 1 day).
If money were no option, I expect a month would be doable in good weather and mild terrain.
