I did not go full length of trail, but the first third is mostly fairly level with only mild grades. My out-of-shape husband did fine. :) Occasional short stretches where trail very rocky but otherwise pretty good footing. Be aware the trail crosses the North River - bring water shoes or prepare to get wet!
Entire trail in the woods, about 1/3 in dense growth (like walking through a tunnel), rest open enough that you can see around you.
A little tricky to find the trail head, and parking is not necessarily at the trail head - we had to walk up the road a bit to get to it.
Trail shared with bikers and horses so stay alert.
