David Walliams' Big Swim: Day 4 | A Sport Relief Challenge

David Walliams' Big Swim: Day 4 | A Sport Relief Challenge This is a documentary looking back on the eight day swim that comedian David Walliams undertook for Sport Relief 2012. Providing the inside story and exclusive behind the scenes access, the documentary takes in all the highs and lows of the outstanding challenge that saw David pass through seven counties, make 111,352 strokes, burn 68,000 calories, battle a serious bacterial infection and even save a dog from drowning as well as enjoy visits from fellow comedians Miranda Hart, Rob Brydon and Jimmy Carr. He may be sat snugly next to Simon Cowell on the judging panel of Britain's Got Talent now, but last year David Walliams endured a massive challenge in order to raise money for sport relief. The comedian took part in a staggering 140-mile Thames swim that raised more than one million pounds for Sport Relief. A documentary team followed David as he struggled through the challenge and made the show, David Walliams' Big Swim: A Sport Relief Challenge.
