18L is 850 m x 30m grass according to the airfield info sheet I have but it's a couple of years old and they do change the length a bit depending on the surface conditions.
But it ain't that long landing an A36 if it's wet, especially with any tailwind....I know as I've landed A36's there day and night on that runway quite a few times in my younger silly days!!
If it's one of his own Roger will not be happy
