After traveling for more than 6,000 miles covering at least 19 countries mostly in Asia and Europe commencing in Hong Kong for more than four months, two British adventurers are now back in London - on horseback - still in their tuxedos.

British Heath Buck and American Doug Campbell said they came up with the idea on raising funds for a charity when they met in a Hong Kong bar.

The duo traveled through remote regions of China, Vietnam, Tibet, Nepal, India, Pakistan and Kazakhstan, all in Asia before proceeding to Europe.

"Heath came up with the idea. Amazingly, I agreed to accompany him," Doug said. "We'd known each other less than two weeks."

"I felt like James Bond at times," Doug added in describing their travel.

The pair said that they had their tuxedos specially made from resilient fabrics in Bangkok, Thailand.

The money they raised, according to the pair of adventurers, has one to local causes, including helping rescued sex slaves in Nepal.
