Danish explorer Torbjorn 'Thor' Pedersen has made it back from his decade-long journey across the world- without flying anywhere.

3572 days of travel, 203 countries, and 358,884 kilometres later, Pedersen has finally completed his ambitious personal mission.

He says he was inspired to take on this challenge after learning that no one had ever travelled across the whole world without setting foot on a plane.

"I was born in 1978, 100 years too late if you want to do anything really remarkable on this planet in terms of geographical feats. They've been to the North Pole, the South Pole, the highest mountain, the deepest seas, the deep, dark forests and the longest river- I grew up feeling I was born too late."
