In February 2007 Martin Strel began an insane attempt to be the first person to swim the entire length of the world's most dangerous river, the mighty Amazon.
Martin is an endurance swimmer from Slovenia, who swims rivers - the Mississippi, the Danube and the Yangtze to date - to highlight their pollution to the world.
Martin is also a rather overweight, horseburger loving Slovenian in his fifties who drinks two bottles of red wine a day... even when swimming.
Unsettling, fascinating and exhilarating. John Maringouin plots a course for the heart of darkness in the company of a 52 year old Slovenian endurance swimmer.
