Have you been following David Walliams 140-mile swim down the River Thames, which should take around eight days? He's coming to the end of his journey now, and what a journey it's been!
So far, David has dealt with freezing cold waters, a nasty tummy bug courtesy of the not-so-clean river and busy river traffic, swimming for up to eight hours a day. Not exactly a pampered celeb charity activity eh?
David is swimming for Sports Relief, and you can support him through the donation page on the Sports Relief website or text Swim to 70011.
