BTW Drew, you said that you're extremely comfortable, I mean really!?!? I ask coz your profile says that you're "under the bed" lol Is it how true Australian used to sleep?
My brother's up for it. Definitely a challenge. I clocked up just over 12 miles today (20km?) and regularly do that three/four times a week so I think I'm in good shape for a small endurance challenge. At least at the end I am somewhere familiar. Get the train back home and have a good damn sleep
