When Karl Bushby left the southern tip of Chile on November 1, 1998, he had just $500 in his pocket and a plan to walk home to Hull, England. The former British paratrooper estimated the journey would take about 12 years. Instead, what became known as the Goliath Expedition stretched into a 28-year adventure covering approximately 36,000 miles.

Bushby set two rules for himself: he would not use transportation to advance the journey, and he would not return to the United Kingdom until it was complete. Visa restrictions sometimes forced him to leave countries before he could continue. During those breaks, he would return to Mexico or the United States, but whenever he resumed the expedition, he had to pick up at the exact spot where he had stopped.

The route took him through South and Central America, North America, Asia and Europe. One of the most dangerous stretches was the Darién Gap, the jungle region between Colombia and Panama, where Bushby used his military experience to avoid armed groups and make his way through the area.

In March 2006, Bushby and French adventurer Dimitri Kieffer crossed the Bering Strait, the frozen stretch of water separating Alaska and Russia. They spent 14 days walking across shifting ice in temperatures as low as minus 30 degrees Celsius. After reaching Russia, both men were detained by border officials for entering the country illegally. They faced the possibility of being banned from Russia, which could have ended the expedition, but an appeals court ultimately allowed Bushby to continue.

Another major undertaking came in 2024, when Bushby swam 186 miles across the Caspian Sea to Azerbaijan. The crossing took 31 days and allowed him to avoid traveling through Iran or re-entering Russia. He then continued through Turkey and into Europe.

The expedition faced repeated delays from geopolitical tensions, wars and visa restrictions. Bushby also lost major sponsors during the 2008 financial crisis, while the COVID-19 pandemic brought further interruptions. He largely financed the journey through his book, Giant Steps, public speaking and, later, support from corporate sponsors and a U.S.-based documentary company.

Now 57, Bushby is expected to arrive in Hull on Monday, November 2, where a civic reception is planned in Queen Victoria Square. He will then walk the final stretch to his childhood home in east Hull, where his mother, Angela, is waiting to welcome him.

A free exhibition at Hull's Monocle building will give visitors an opportunity to see photographs from the journey, excerpts from Bushby's diaries, letters he sent to his parents and "The Beast," the custom-built trolley he used to carry his belongings.

Charlie Allenby, owner of the building, said the exhibition will showcase Bushby's achievement and give visitors a chance to learn about his experiences. He hopes the story will inspire young people to take chances and pursue something outside the ordinary.

The exhibition is scheduled to remain open until early 2027.
