I thought it was pretty easy, I never put my feet down.
The toughest as I remember was the steep right hand turn off of Mulberry north onto NF64.
There are couple of steeper sections and switchbacks that I did not get pics of, but all of it is Stromable.
It might have taken a bit over an hour to run, I honestly don't remember, but it's definitely worth going that way IMO.
I did not do it, but there is a lake up there that I hear is worth a stop.
I ran it from its intersection at 52 (about 7-8 miles east of Ft Mtn park) all the way into Blue ridge.
It did turn paved for the last 2-3 miles into Blue ridge as I recall
I believe you can also pick it up on gravel near Chatsworth, but I did not run that way.
I prefer to run 52 up over Ft mountain (nice twisty paved run) then pick up Mulberry, NF64 and Hwy 2.
There is a chicken farm where Mulberry turns off of 52.
