also it was the all time classic 'ive started so ill finish'. but seriously if any1 now thinks they will do a sponsored walk like this. Do just a lil training, drink water slowly but steadily, wear a sun hat, dont carry extra stuff ( ideally get some ground crew), make sure all your straps and bindings are comfortable. Im a postman im on my feet walking and cycling for hours a day and even for me in that temperature the last couple of K's were hard, for others i know it was really really difficult.
