Chased by crocodiles, capsized in the Atlantic and arrested as a potential spy in Egypt.

Sounds like the latest action-packed 007 instalment. But this is no Hollywood blockbuster - in fact the star of this death-defying deluge is a little closer to home.

Dorset adventurer, Jason Lewis, is preparing to complete a 13-year, human-powered round-the-world expedition.

During his 46,000-mile, 360-degree odyssey he's experienced a catalogue of hair-raising adventures, circumnavigating the globe by foot, pedal boat, kayak, mountain bike, roller blades - and even swimming a river.

The 40-year-old from Askerswell is now preparing to pedal boat cross the Channel and cruise up the Thames to his original Greenwich Meridian starting point.

After a 2,000-mile mountain bike marathon through Europe from Istanbul, Jason is currently on the coast of Belgium for the last leg of his journey. Within the next few days he will start his final voyage in the record-breaking Moksha - a 26 foot, £26,000 wooden craft, built in Exeter, Devon, in which he has conquered the world's oceans.

Jason admitted that when the expedition finishes "it will be like a huge portion of my life over".

"I am going to feel torn between saying goodbye to it, and at the same time I am looking forward to moving on to other things," he said.

"It is going to be very difficult putting it to bed."

Jason' epic adventure began in July 1994 although it didn't get off to the best of starts. After setting off from London for the south coast he and original companion Steve Smith, got "horribly lost" on their way to Rye.

After pedalling the world's busiest shipping lane to France they biked to Lagos in Portugal and began the 111 day voyage to Miami - suffering a near miss with a trawler, and were tipped over by a whale.

Undaunted, Jason completed the first roller-blade crossing of the USA in September 1996 after spending nine months recovering from compound breaks to both legs, a result of being run down by a driver in Colorado.

Smith left the expedition in Hawaii to pursue other interests and in August 2000 Jason arrived in Australia - the first person to pedal the Pacific in a total of 178 days. There followed an 88 day, 3,200 mile mountain bike ride from the Queensland coast to Darwin via Alice Springs and a 3,000 mile pedal boat, kayak and bike ride up the Indonesian archipelago to Singapore.

His mental and physical stamina was pushed to the limit during his 7,000 mile solo bike trek from there to Mumbai, India - via Malaysia, Thailand, Laos, south west China and Tibet where he rode 1,600 kilometres at night to avoid Chinese police.

At the beginning of this year Jason reached Djibouti on the Horn of Africa and after being questioned as a potential spy after entering Egyptian territory without permission he arrived in Istanbul in Turkey in March 2007. A month later he began the long mountain bike haul through Europe to Ostend in Belgium where he is poised for his final pedal boat voyage back to the UK - and the end of his adventure.

"My home has been the road for so long now that I have become disconnected from any one physical place or culture." Jason said.

"Home is now a nebulous concept connected more to people than physical places.

"Perhaps it is inevitable now that I have just turned 40, but I think I am ready to trade in my travelling boots for a set of regular shoes - for a while at least."
