 ⇒Beijing pollution risky for endurance athletes | U.S. | Reuters

BEIJING (Reuters) - Endurance events at the Beijing Olympics could pose a health risk if they are staged on heavily polluted days, the International Olympic Committee said on Wednesday, although it was prepared to reschedule such events.
 
Hein Verbruggen, chairman of the IOC coordination commission, said there was a small chance of athletes suffering some damage to their health if they took part in events lasting longer than an hour, such as the marathon and cycling road races.
