Another thames challenge to follow

David Walliams has started this morning his attempt to swim the length of the Thames in seven days. Apparently colder than expected, he's eventually decided to use a wetsuit. I cannot blame him really...

As they advertise it, "WARNING DO NOT TRY THIS YOURSELF. The tidal Thames is incredibly dangerous and many people have drowned in its waters which have powerful tides and unpredictable currents". So up to Richmond is fine then :) Lewis Gordon Pugh, who has actually done the full length from the source (starting by running) to South-end-on-Sea, said the biggest danger was coming from objects immersed just under the surface. For Charlie Wittmack, it was probably more a bacterial threat, as he became violently ill during his attempt.
