what u plan for the top half of the Canning sounds logical and commonsense (i figure you are not a government beauracrat) with the bonus of 12kg less weight -- 18 down to 6
Elsewhere in the outback on the Connie Sue, one ride we had, we had bike probs and were about 50-60km short of our destination at Warby which we had banked on with water supplies.
Myself, dinner was a cup-a-soup with half a cup of water left in the camelback (the high salt content just made my dehydration worse) - I'm a dickhead
One of the other riders Peter the next morning had a severe headache. At Warby there was like 4 camels drinking the well dry. I know i drank 6ltrs, a 2ltr can of tomato juice, 2ltr can of fruit juice and over 2ltrs of water before i felt quenched.
