Though he lost his eyesight as a teen, Mok Kim-wing has never relinquished his vision to make life better for the disabled.
Despite his blindness, Mok has always been a runner and has long promoted the sport in Hong Kong's disabled community. But it was the founding of the Fearless Dragons running club three years ago - a unique partnership between blind and deaf runners - which has seen him take his dream for the community to a new level.
As part of the Fearless Dragons, the 49-year-old social worker has run many marathons around the world. Last year he ran the Kyoto Marathon and raised HK$200,000 for the local disabled.
Together with his deaf partner, Eric Yeung Yuk-wing, he aims to complete this year's Standard Chartered Hong Kong Marathon within five hours.
Then when I was 13 a classmate hit my other eye, causing retinal detachment. Unfortunately, the operation failed and I became completely blind. I have learned to accept my fate. The experience has given me courage to take on new challenges.
