Adventurer Karl Bushby is to complete his 28-year walk home from Chile in Hull, where his mother and son await

Karl Bushby, 57, is expected to arrive at Queen Victoria Square in Hull at 11am on Monday, completing the longest unbroken walk in human history — 31,000 miles across 30 countries and four continents over exactly 28 years. The former paratrooper left Punta Arenas, Chile in 1998 with just $500 and set himself two rules: no motorised transport and no returning home until the job was done.

Bushby will meet his 12-year-old granddaughter for the very first time on arrival — a child born during his epic trek.

His mother Angela, 79, says her opening line will be: 'What time do you call this?' — after giving him a hug.

The only item to survive the entire 28-year journey is his Paratrooper 'Flying Pegasus' badge.
