On the channel swimmers group, I came across this scientific study that examined hypothermia in swimmers during the 2006 Rottnest Channel swim. For those who can't be bothered to read the article the conclusion was that an increase in BMI (weight) reduced the risk of hypothermia. And surprise surprise... a prolonged duration of swimming increased the risk! Therefore in summary, carrying a little fat helps but the quicker you do it the better.

Now... do I go for a swim or a McDonald's?
Wayne likes pork pies and Guinness. He likes routine and predictability. He loves his family. He's 40+, short(ish), balding and battling with waistline expansion. He's been known to occasionally play a good round of golf, likes to tinker with 'stuff' and has rescued a group of friends from the African wild by fixing a Land Rover with a jellybaby.
He's never been a great fan of physical exertion. In short (apart from the jellybaby incident), Wayne is an ordinary person. And he's about to do something really amazingly, astoundingly and astonishingly extra-ordinary. He's going to swim the the treacherous, never-been-swum-before channel between Kintyre (Scotland) and Ballycastle (Ireland). For charity. This is his story.
