The Beijing Summer Games are shrouded in a marathon-mystery, as contingency plans for the 42-kilometre-long competition remained a closely-guarded secret on Friday.
Chinese organizers remained mum over emergency plans should the Olympic marathon competition, scheduled for the day of the closing ceremony on August 24, not go ahead as planned because of the smog blanket covering Beijing, reported dpa.
"We have a contingency plan," Liu Wenbin, a deputy directory in charge of the competitions of Beijing's organizing committee, said Friday.
Liu, however, refused to unveil any details of the organizer's back-up plan. "All competitions will be finished before the closing ceremony," he insisted.
The International Olympic Committee earlier did not rule out that competitions in endurance sports had to be rescheduled on short notice because of high humidity and smog in the Chinese capital.
