A lone adventurer attempting a human-powered round-the-world trip has passed the highest point of his journey - which began 12 years ago.
Jason Lewis hopes to complete his expedition next summer
Jason Lewis reached 16,732ft (5,100m) on the Tibetan plateau during the latest 7,000-mile (11,265km) mountain bike leg from Singapore to Mumbai.
Mr Lewis, from Bridport, Dorset, is now cycling through Nepal's rainforests.
The 38-year-old said it was now "all downhill to Greenwich" - the London start-finish point he left in 1994.
Mr Lewis has completed more than 5,000 miles (8,047km) towards his Indian destination, which he hopes to reach next month.
He said his trip nearly came to a grinding halt when the gear hub of his battered mountain bike came apart on a muddy road.
But two Irish cyclists he had met helped him "cobble together" the wheel to enable him to carry on pedalling.
The round-the-world voyage began in London in 1994
In all, Mr Lewis has clocked up more than 40,000 miles (64,374km) since his muscle-powered marathon began.
He has also used his wooden pedal boat Moksha to cross the Atlantic and Pacific oceans, roller blades to cross the North American continent and a kayak to get from Australia to Singapore.
The final leg of his Expedition 360 is set to include a 2,200-mile (3,540km) pedal boat crossing of the Indian Ocean from Mumbai to Djibouti on the horn of Africa, from where he will continue through Ethiopia, Sudan, Egypt, the Middle East and finally Europe.
He is expected to finish at Greenwich in London in the summer of 2007.
