Ananova:

Two adventurers have successfully completed a charity trek from Hong Kong to London on horseback - wearing tuxedos.

Briton Heath Buck and American Doug Campbell came up with the idea after they met in a Hong Kong bar.

They saw 19 countries on their four-month, 6,000-mile trip.

They travelled through remote regions of China, Vietnam, Tibet, Nepal, India, Pakistan and Kazakhstan, then across Europe.

According to the Sun Doug said: "Heath came up with the idea. Amazingly, I agreed to accompany him. We'd known each other less than two weeks. I felt like James Bond at times."

Their tuxedos were specially made from resilient fabrics in Bangkok, Thailand.

The money they raised along the way went on local causes - including helping rescued sex slaves in Nepal.
