Blind Hong Kong runner becomes first visually impaired person to complete Antarctic challenge
Gary Leung beats the odds and injury to place sixth overall in 100-kilometre South Pole race in bid to raise money for Samaritan Befrienders

A blind runner from Hong Kong has become the first visually impaired athlete to complete a special 100km race in the South Pole, overcoming an injury he suffered at the 40km mark.
Gary Leung Siu-wai, 49, and running partner Jennifer Cheung Sze-ying, 42, ran the event in a bid to raise funds for the Samaritan Befrienders Hong Kong following a wave of student suicides last year.
The pair withstood freezing temperatures to take on the epic challenge from January 21 to 22.
The event is part of the World Marathon Challenge 2017, which sees competitors attempt to run a total of 295km in seven marathons across seven continents in seven days.
They flew from Toronto to a heroes’ welcome at Hong Kong International Airport on Monday. They received flowers and cuddly toys while proudly displaying their trophy to waiting photographers.
