Photographer David Clifford has captured the world's most dogged runners doing what they love in the most remote and unforgiving environments.
Aiming for the 'ambience and convenience of a five-star hotel room' Cathay Pacific's first class doesn't just have seats, oh no. You get a private relaxation suite with a seat that can turn into a chair, chaise longue or a bed. There's even room in your 'suite' to have a friend over for in-flight drinks or a business chat with a colleague.
Ambient lighting changes in the cabin help you relax and sleep, along with noise-canceling headsets to block out any snore-y fellow passengers. If you're feeling peckish, you're in luck, all meals are cooked to order and there's no pinged microwaved meals here. The first class galley boats rice cookers and steam ovens to whip up Asian or International dishes.
