Think you're fit ???

The guy was on breakfast TV. He was looking 'plump' - he is trying to put weight on in preparation for the swim. In much the same way I expect as a seal does.
I am also at the moment following a similar training regime, just without the swimming bit.

Yes, I was encouraged by his portliness! Seemed like a nice chap. Mad, but nice. I liked how he said he had an electronic thing to wear on his ankle to deter sharks, but wasn't convinced the quoted "feeling of discomfort" it caused would really put off a determined shark....
