Nor never a drop to drink!
Swimming 140 miles in the cold water of a tidal river would take all a man’s strength, grit and determination in itself. But Mr Walliams also had to cope with the effects of heavy pollution in that water. Within twenty four hours he was suffering from diarrhoea and vomiting, which must have made swimming interesting.
Thankfully, his own ability to fight infection was boosted by the best medical care. He had antibiotics and inoculations to help him cope. And he knew that when he reached Westminster his trial would be over, he could step on to Terra Firma and know that from then on, the water he would use to drink and bathe would be clean and purified.
