What on Earth would drive a man to swim in Arctic waters wearing nothing but Speedos, goggles and a cap?
For Lewis Pugh, it was a love of the environment and a passionate desire to save the Arctic from global warming.
His 1 km swim (0.62 of a mile) in 2007 made him the first person to complete a long-distance swim at the North Pole -- the purpose, to highlight the fact that it was possible to swim for a kilometer in a place that should be solid ice.
Pugh, now aged 39, is a former maritime lawyer who abandoned his practice six years ago to become a full-time environmentalist and adventurer.
Since then he has become the first person to complete long-distance swims in all five of the world's oceans and has become the world's leading cold water swimmer.
