Lewis Pugh swims across Mount Everest glacial lake to highlight climate change

Extreme swimmer Lewis Pugh swam 1km across a glacial lake on Mount Everest to highlight the issue of climate change

Adventurer Lewis Pugh, known as the ‘human polar bear’ for his extreme swimming challenges, has safely crossed a glacial lake on Mount Everest at over 5,000m to raise awareness of global warming.

Pugh, who has previously swum in Antarctica and the North Pole, not only had to battle extremely low temperatures of 2 degrees centigrade (36 fahrenheit) without a wet suit, he also had to cope with altitude sickness.

“It’s one of the hardest swims I’ve ever undertaken,” said the 40 year old. “Swimming 20 metres at full speed in the test swim I felt I was going to drown.”

“I was deeply concerned I wouldn’t make 1km and I’m delighted that I’ve finally achieved it…I had to find a delicate balance between going too fast in which case I might drown due to hyperventilation and going too slowly and risk dying of hyperthermia.”

Lewis swam the 1Km challenge in 22mins 55 seconds. You can see the swim on YouTube below:
