I did the Cape on a bike with 7 mates in 02.
We where warned the start of day 2 is the most dangerous,and where most get hurt,The first day everyone is keen and excited but cautious.
Day two everyone is keen to get going....Until the first off 15 minutes in broken wrist for one,half hour later two off with too much heat into a corner.
When you come up for a swim just go in boots and all,dont bother taking anything off.
If you get the chance do a chopper ride at the top,We went around the top and across to Thursday Island.
It was $2200 when we done it on DRZ 400's...
