The Hong Kong Marathon is an annual marathon race.
It is the Hong Kong's largest outdoor sporting event that attracts some of the top runners from around the globe every year, and is participated by around 70,000 participants.
The organization urged the participants not to take 'selfies'. Last year, multiple runners got injured because of people stopping to take pictures.
