Endurance swimmer Lewis Pugh is to swim a kilometre across a lake on the Antarctic ice sheet to raise awareness of the climate crisis at the poles.
The latest challenge by the UN patron of the oceans will see him swim in a stretch of water no human has swum in before as he tries to drive action to create a network of protected areas in the ocean around the continent.
In the run-up to the swim, which will take place in January, Mr Pugh has put an advert in the jobs section of The Times looking for people to train with him off the Isle of Lewis in the Outer Hebrides from December 29.
He will swim one kilometre (0.6 miles) across a “supraglacial” lake, which form when melting water collects in depressions on the surface of glaciers or ice sheets, in East Antarctica.
