No disrespect Bob, but you can see the markings - these little cane sticks with a bit of tape on the top, hidden amongst all the rushes.
NMNC - why should the RO be expected to assess a runners ability to navigate?
Typically an RO puts on a race and advises "NS" because that RO feels that there may be circumstances in which the runner may need to navigate.
That should be the end of it surely?
If the RO goes a little further and advises in pre-race info(for example) "The nature of the terrain and changeable weather conditions in the area that this race covers means that runners should be competent navigators." then that underlines it.
