Little Britain star David Walliams is attempting to swim across the English Channel for Sport Relief.
Walliams will attempt to swim the English Channel for Sport Relief
Walliams, 34, will be aiming to raise funds for BBC Sport Relief on his epic 21-mile Super Swim.
David will brave freezing waters for up to 16 hours, dodge tankers and plough through seaweed on his aquatic adventure.
But he needs your help and sponsorship to keep him afloat - so please go to his website to pledge your support.
More people have managed to climb Everest than successfully swam the English Channel, so David knows he will have his work cut out:
"It's terrifying, utterly terrifying - six people have died doing it, so yes I am a little bit worried," he admitted.
"It was kind of my idea but I hadn't really thought how hard it was - you can't touch the boat, you can't touch anyone else, you can't even wear a wet suit.
It's terrifying, utterly terrifying - six people have died doing it, so yes I am a little bit worried...
"The training is going well I have done 25m now! No seriously I am off to Croatia next week for an eight hour swim."
David has teamed up with Greg Whyte from the English Institute of Sport to oversee his training schedule.
"The English Channel is the blue ribbon event of endurance swimming and represents one of the toughest physical challenges on the planet," said Whyte.
"David has been working tirelessly over the past 11 months to make an attempt on the channel.
"He has demonstrated a level of work and commitment as great as any elite athlete I have met."
Even so less than 10% of people who have attempted the challenge have succeeded in reaching France.
So David will need as much of your support as he can get.
The story of David's enormous undertaking will be documented in a one-hour programme, Little Britain's Big Swim, on July 14th.
