Debra - yes, I had a few hairy moments on the road as well, so I'm hoping there will be signposts to offroad paths as well.
I'm supplementing the malt loaf with jam sandwiches now, which I've discovered are a great morale booster. Unfortunately they don't transport well on the run, so I might leave one at the Sandilands feed stop as something to look forward to.
Loulabell - that's a shame. I have a friend who's doing the 10k as well, so we're going to carb up together the night before (OK, so you don't really need to carb up for 10k, but who's counting?).
