British adventurer Graham Hughes has managed to visit all 201 UN recognised countries without travelling by plane or driving himself.
"I did it because most people said it was impossible and because it was a travel adventure which hadn't been done before" he said.
Hughes set off on his adventure on January 1, 2009 from Uruguay travelling for 1,426 days on a $100 a week budget. He finally completed his journey in the world's youngest country, South Sudan.
