I was a expecting to walk-run a marathon on a trail starting from Yorktown park. Instead it was all road. That was fine but a little dangerous. 99% of drivers went out of their way to move a little extra toward the center of the road when approaching. It would be nice if there was a nice distinguishable line a foot or two for trekkers because the views the river, the woods and rolling hills gives you everything you want. Plus exactly 13.1 miles from Yorktown in the turnaround you find yourself right in the midst of Colonial Williamsburg, costumed employees in tricornered hats, reconstructed tavern and courthouse, horse poop smell, etc.
