Stève Stievenart, the extreme swimmer, managed to cover a kilometer in the freezing waters of Antarctica. A new feat for the Wimereusian who completes a well-stocked track record.

Previously, the 46-year-old swimmer had crossed the English Channel six times. Eating only fatty fish, taking cold showers in your garden, wearing shorts all year round, sleeping with the window open and swimming among jellyfish are among the many methods used by the northerner.
