Now this is a different kind of water-skiing! Incredible pictures show pair of adventurers body board their way down Europe’s largest glacier. Carving their way through the icy rivers of the Aletsch Glacier in Switzerland, they are seen risking their lives for an adrenalin rush. Claude-Alain Gailland and Gilles Janin were pictured mounted on their body boards as part of a sport known as hydrospeeding. The daredevils risked being carried away by strong currents and even drowning in hidden crevices to complete the winding seven-mile journey. Only a handful of guys in the world who can do it, as it requires a lot of knowledge and expertise.
