North Umpqua trail in Oregon

Hello,

I am new to this but I am planning on doing a 4 day bike/backpacking trip on
the north Umpqua trail (I think that's right) in Southern Oregon. We are
all fairly new to this and I did notice it is single track. Are there
anything that we novices need to know as far as the trail goes. We are in
good shape but I know the technicality of the trail can make a difference.
I also wonder if there is a protocol for avoiding bikers coming the other
way (especially when close to a bend where you may not see the person until
you are a few feet from them). I realize this is a broad question but any
insight or info would be greatly appreciated.

Luke
