I was on the 'large' inactive bit of the runway off to the side, where in fact I was supposed to be. As I say, it wan't a problem I just thought it was a bit confusing....and then as I was lining up and called 'G**** lining up and taking off' there was a little voice popped up on the radio saying 'Are you on the grass or the hard?'...
the wait to be not on the runway itself but at a holding point.
There isn't an actual taxiway to the end of the runway, the taxiway is the runway, but not the marked runway....confusing innit?
