It is a nice trail that I like to ride after work. It has about 3.5 miles of gravel road with nice boardwalks across marsh regions and then about .5 miles of nice single track through the woods. Just about all the track through the woods is up hill and there is a killer climb about mid way. At the end of the trail there is a parking lot where you can turn around.
Review: The NRT is a very well maintained greenway of ample width for bikes in both directions while allowing for walkers, joggers, strollers, etc... just watch out for dogs on retractable leashes with inattentive owners.
Review: The trail has recently had an addition 26 miles or so of additional greenway trails and bridges. It originates at the horseshoe farm park and travels south east into Johnston county. In the near future the northern leg will connect the upper trail from falls lake to the bridge at hwy 401.
