A change in regulations could make an intended route unavailable.
Eventually, these challenges consumed years.
Financial pressures also threatened the expedition.
The global financial crisis of 2007–2008 disrupted sponsorship arrangements and reduced the money available to support his travel.
Without sufficient funding, Bushby could not always pay for necessary equipment, accommodation, immigration procedures, and logistical support.
He spent extended periods away from the expedition route, including time in Mexico, while attempting to secure new financial backing.
But he refused to abandon the challenge.
In 2012, after encountering another Russian visa obstacle, Bushby undertook an unusual protest.
He walked approximately 5,600 kilometers across the United States toward Washington, D.C., seeking to draw attention to the restrictions preventing him from continuing through Russia.
It was an extraordinary response to a bureaucratic problem.
Rather than simply issuing complaints, he used the activity that had come to define his life.
He walked.
The effort helped attract attention to his circumstances, and he eventually obtained permission to return to Russia.
Bushby's official expedition history documents the long interruptions caused by immigration restrictions, the loss of financial sponsors, and the efforts required to restart the journey.
These delays changed the nature of his original ambition.
A journey intended to take 12 years was becoming something far larger than a conventional expedition.
It had begun to consume entire chapters of his adult life.
When a Global Pandemic Stopped the World
By the late 2010s, Bushby had traveled across Russia and through Mongolia before continuing toward China and Central Asia.
At this stage, it appeared that his long-awaited return to Europe might finally be approaching.
But the world was about to change.
In early 2020, the COVID-19 pandemic prompted governments to impose unprecedented restrictions on international travel.
Borders closed.
Visa services were disrupted.
International movement became tightly controlled.
For a man whose entire expedition depended on crossing national boundaries under his own power, the consequences were enormous.
Bushby had already spent years overcoming immigration obstacles, and the pandemic introduced further uncertainty.
At the same time, tensions involving countries along possible routes continued to increase.
The deteriorating geopolitical environment complicated his plans to move westward through Central Asia and toward Europe.
Following Russia's full-scale invasion of Ukraine in February 2022, potential routes involving Russia became even more difficult.
Iran and Turkmenistan presented other significant administrative and geopolitical obstacles.
After years of examining alternatives, Bushby faced a remarkable problem.
He had already traveled across continents, crossed dangerous wilderness, and endured Arctic ice.
Yet he could not find a practical authorized land route that would allow him to continue without compromising the conditions of his expedition.
The obstacle was not simply geographical.
It was political.
Rather than abandon his rules, he searched for another solution.
Eventually, that solution would involve crossing one of the world's largest inland bodies of water.
Swimming Across the Caspian Sea
In 2024, Bushby undertook one of the most physically demanding stages of the Goliath Expedition.
He decided to cross the Caspian Sea from Kazakhstan to Azerbaijan.
The decision was extraordinary.
The Caspian Sea is the world's largest enclosed inland body of water, stretching between Europe and Asia.
Although technically classified in various contexts as a lake or inland sea, its enormous size and challenging weather conditions make extended open-water crossings dangerous.
For Bushby, swimming across it offered a route around political barriers that had prevented him from continuing overland.
But the proposed crossing involved hundreds of kilometers of open water.
It required extensive planning, maritime support, medical considerations, and cooperation from other experienced swimmers.
Bushby did not attempt the crossing entirely alone.
His team included fellow long-distance adventurer Angela Maxwell and Azerbaijani swimmers, supported by vessels and logistical personnel.
The swimmers used equipment appropriate for prolonged open-water travel, and the undertaking involved repeated periods of swimming and rest.
The entire operation lasted 31 days.
According to Bushby's official expedition account, the team crossed approximately 288 kilometers, or 179 miles, from Kazakhstan to Azerbaijan, spending more than 132 hours in the water during the journey.
They faced waves, currents, seasickness, exhaustion, and the mental challenge of repeatedly returning to the water.
In September 2024, the team successfully reached Azerbaijan, completing a milestone that brought Bushby significantly closer to Europe.
The achievement was not a conventional nonstop swim. It was a staged, supported expedition across open water, undertaken over several weeks.
