52-two-year-old Slovenian marathon swimmer Martin Strel has become the first person to swim down 5,265 km South America’s Amazon River breaking his own three-year world record set in China. He averaged about 80 km a day in the swim from Peru to Brazil. Strel has described his swim of the world’s second longest river as his toughest expedition by far. Strel was ordered by his doctor to stop his epic journey as he was suffering from dizziness, vertigo, high blood pressure, diarrhoea, nausea, and delirium but his obsession drove with reaching his final destination drove him to continue on and even undertake night swimming. If confirmed by Guinness World Records, the Amazon swim will be the fourth time Mr. Strel has broken the world record for long-distance swimming.
