In the States there are a few semi formal groups who put on the Everglades challenge and the Texas 200.
I always though that The Broadwater up to Brisneyland and beyond would be a perfect venue for this type of event.
Are Ozzies too busy to pull something like this off?

P.S. Just remembered the name of one of the groups, The Watertribe. Been doing it for a while.
