I realize that this answer can vary a lot depending on the person. I am hiking the 11.4 mile trail. From Black Mountain campground to the summit: 3600 feet. I am a female in my 20's and I hike a lot. Even though I hike a lot I am usually on more or less of flat ground and carrying a large pack. I plan on just carrying a large-ish day-pack for this hike. Thanks!
