Charlie Wittmack plans a new slant on climbing Everest, by completing a triathlon that is being publicised as the possibly the toughest human endurance event yet conceived.
The 33-year-old practising lawyer from Iowa, who is also involved with the Department of Global Health at Des Moines University, starts in the UK with a 275-mile swim down the Thames to the sea and then across the English Channel to France.
From there he is planning to cycle 9,000 miles across Europe and Asia to reach the Bay of Bengal, his projected route taking in Ukraine, Russia, Kazakhstan, Kyrghyzstan and China.
He will then run c950 miles from sea level up to the Nepalese Himalaya, where he hopes to finish his odyssey on the summit of Everest.
