You're probably right there mate! I have a friend though, who does adventure hiking racing. I'm not sure what it's called but basically he goes out in a small team and they run/walk for days, plus camping, to get across a determined track and set their time. He's obsessed with it and I think it's quite a trend for corporate execs to get that mind-refreshing time plus exercise on a weekend.
Point being... if they can do that down under... there's hope for me :-)
