No-one had ever circumnavigated the earth under their own steam - no motors, no sails. But Jason and his friend Stevie Smith had little experience. They thought the trip would take two or three years and be the adventure of a lifetime. Instead it took more than 13 years.
They set off from the Greenwich Meridian Line in London in 1994 and cycled through Europe before heading out over the Atlantic on a unique pedal-powered boat. Named Moksha (meaning liberation in Sanskrit) the custom 26ft (8m) pedal boat had a top speed of three knots, was self-righting and held supplies for months at sea.
Taking shifts at the pedals and the single sleeping compartment the pair made it to Miami in 111 days. Jason then continued his journey on roller-blades until he was hit by a drunk driver, breaking both his legs and landing him in intensive care. Nine months later he continued to San Francisco and onto the Pacific, to Hawaii.
