The route looks complete to me ! From mile 14 to 29 it goes through Olveston, Elberton, skirts Littleton-Upon-Severn, up a certain hill, then Alveston, Thornbury, Oldbury Naite, Hill and Newton.
If you still keep getting a map with a bit missing let me know and I'll "save" it again.
Anyone else getting Andy's problem with the route ?
