Martin Strel holds successive Guinness World Records for swimming the Danube river, the Mississippi River, the Yangtze River, and the Amazon River.
Bloke is a nutter!
I wouldn't swim in the Amazon for quids, never mind do the whole length, too many lurgies and bities.
It's got crocs, electric eels, freshwater stingrays, pirahnas, anacondas, water spiders, sharks and probably even Nessies brother.
What an absolute legend
Maybe he did backstroke.
ooohh hang on then he'd have to jam something up his nus
..... Yup .
He's bloody brave. Hate to think of the training regime!!
