It is the only race in Bangkok to be held at midnight, and offers competitors a choice of 2 distances - 6km or 12km. The city streets will be closed and protected by a police and security contingent of about 400 officers, and supported along the route by local residents, and shop owners together with the management and staff of the Amari Watergate Hotel Bangkok. The atmosphere is tremendous, with over 5000 runners, both local people and foreigners. The winners for the best record in 12km of male and female championship will receive the Royal trophy of HRH Princess Sirindhorn. The proceeds from the event will be donated to some very worthy causes such as supporting the education of children whose parents have very tragically passed away due to HIV infection and supporting for a Better Life Project which supports educational opportunities for underprivileged children in poor areas of Thailand.
