Pakistan's sole representative at this year's Winter Olympics at Sochi is gearing up for the Giant Slalom competition.

Muhammad Karim, 16, grew up in Pakistan's remote northern region of Gilgit-Baltistan and taught himself to ski without proper equipment. His parents could not afford it, so he started off with home-made wooden ski poles, when he was just five.

He told the BBC: ''I think of every skiing competition as my last competition. That way, I ensure that I give it my best.''
