Comedian falls behind schedule in 140-mile swim for Sport Relief but has still raised more than £200,000 David Walliams is falling behind schedule in his charity river swim after coming down with “Thames tummy”. The comedian has been ill with a high temperature, vomiting and diarrhoea but has still managed to raise more than £200,000 for Sport Relief three days into his challenge. He said: “I always knew there was a risk that taking in the water could cause problems, but now it’s happened it’s still hit me really hard. I was sweating in the night and have been to the toilet a lot this morning. This is already much harder than I thought it would be… and London seems a long way away.” The Little Britain star, 40, is swimming 140 miles over eight days from Gloucestershire to London.
