HONG KONG: Hong Kong is known for its long working hours and rat-race lifestyle, but on the rugged trails of the surrounding hills extreme runners are driven by a different ambition - the ultimate 'ultra' experience.
Defined as any distance beyond the 42.2-kilometre (26.2 mile) marathon, ultra races are becoming increasingly popular around the world - and with its 300-kilometre network of trails criss-crossing rocky terrain, exposed peaks, bays and reservoirs all close to the city, Hong Kong is increasingly being seen as the ideal venue.
