The story of Karl Bushby is one of the most ambitious endurance journeys anyone has attempted. In 1998, he set off from Punta Arenas, Chile, driven by a simple bet: to walk back to England without using any form of transport. What started as a challenge turned into a 27-year quest known as the Goliath Expedition, a continuous route around the planet driven solely by his footsteps.

He crossed the Darién Gap, one of the most impenetrable jungles in the world that very few traverse on foot, and later managed to walk on the shifting ice of the Bering Strait, one of the most iconic achievements of his journey.

Along the way, he faced legal issues in Russia, including a period of detention related to his visa. Even with delays, obstacles, and extreme environments, he continues to move towards his goal. His determination has transformed a bet into a historic attempt to complete a journey around the world solely by walking.
