Alastair Humphreys has spent over four years cycling round the world, a journey of 46,000 miles through 60 countries and five continents. He's walked across Southern India following the Kaveri river, rowed the Atlantic Ocean, ran the Marathon des Sables, completed a crossing of Iceland by foot and packraft and participated in an expedition in the Arctic, close to the magnetic North Pole. Alastair has also recently returned from walking across the Empty Quarter retracing the route of one of his heroes, Wilfred Thesiger, walking 1000 miles in 45 days through the desert in Oman.

In the spirit of ideas worth spreading, TEDx is a program of local, selforganized events that bring people together to share a TEDlike experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, selforganized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are selforganized.* (*Subject to certain rules and regulations)
