Some people take a gap year. Karl Bushby took 28 years. The 57-year-old Briton arrived back in his hometown of Hull on Monday, 2 November, finishing the Goliath Expedition — a round-the-world walk that began in Chile in 1998, when he was 29. He completed the last few kilometres pushing the same cart that had carried his gear for most of the journey, greeted by crowds and an emotional reunion with his mother, Angela, outside her house.

The rules he set himself were brutal: no motorised transport to advance the route, and no going home until it was done. Over roughly 48,000km, that meant more than 10,000 days away, hauling himself north from Chile through Central America, the United States and Canada, then across into Russia and onward through Asia and Europe.

The obstacles read like an adventure novel. He ran into armed gangs in the Darién Gap, spent time in a Panamanian jail, and was threatened by a polar bear in Siberia. Visa headaches and geopolitics repeatedly stalled him. Perhaps the most extraordinary chapter came in recent years, when he reportedly swam for 31 days across the Caspian Sea to bypass travel restrictions linked to the war in Ukraine. Last month he crossed the English Channel, and on 2 November he finally set foot on home soil — on foot, as promised.

Bushby credits the huge network of people who helped along the way, and he is candid about how strange homecoming feels. England itself is unfamiliar: he has had to relearn which side of the road to check and even recognise products in shops. His message to anyone watching: dream bigger, and don't underestimate what you're capable of.

Why should a traveller care? Partly because it's a reminder of how connected — and how complicated — the world is. Bushby's route stitches together some of the planet's most storied overland corridors: the Pan-American route through the Americas, the Bering Strait crossing into Russia, and the long overland trail back through Asia and Europe into Western Europe. His story turns those names into something real: the Darién Gap is as wild and lawless as its reputation suggests, Siberia is genuinely bear country, and borders can close in an instant, as his Caspian detour proved.

For most of us, the takeaway isn't to swim the Caspian. It's that slow travel — walking a stretch of coast, hiking a long-distance trail, crossing a region under your own steam — shows you a version of a place you'll never see from a tour bus window. Bushby spent three decades proving how much world exists between the airports. His expedition is over; the idea of it is a pretty good excuse to lace up your boots and plan something longer than a weekend.
