You're welcome. You will be fine and will fall in love with this trail, as have countless others. Only once have I seriously thought I was going to die while hiking the BMT.
October, 2015, I attempted a loop hike of the old and new BMT in Joyce Kilmer/Slickrock Creek wilderness. It was rainy, muddy, steep, and slippery so I was too slow and had to shorten the trip.
I started at Beech Gap, spent the night at Naked Ground, and hiked south the next morning. I turned off the BMT onto Ike Branch Trail which hadn't been maintained and was considered impassable (it took hours to traverse), spent the night next to Slickrock Creek, forded it 12 times (water was above my knees), and hiked up Big Stack Gap trail. Definitely the most difficult hike I've ever done.
Happy trails!
