I guess I had the advantage of having no-one else around me when I went for it but from the Civic Centre, I just ran across the sand keeping myself roughly the correct distance from the embankment and car park (ignoring the green because it's not possible to use it at that scale and speed) and hey presto! a gully materialised in front of me. Carol appeared as I was leaving and seemed pleased to see it so not sure if she'd had troubles or just happened along at that time. Cleats were okay for the sand but not so for running along the road and paths.
I did attempt to leave the Civic Centre from #3 heading NE towards #2 by going over the (grey) railing but then decided running through the ballet probably wasn't a good move so had to run back past #4, which I'd just collected.
