“Faced with the prospect of dangerously high levels of air pollution during the Games, International Olympic Committee officials have warned that competition in endurance sports, such as the marathon and long-distance cycling, might be postponed or even canceled. The world’s fastest marathon runner, Haile Gebrselassie, has already withdrawn from the Olympic race for fear that air pollution might permanently damage his health. Many athletes are planning to take precautions, such as arriving in Beijing as late as possible, coming well equipped with medication for possible asthma attacks, and wearing masks once there.”

Thank you to Mike Smith for the pointer to this great summary of the issues surrounding the Beijing Games, as well as to WSJ’s pollution graph (with pictures for some of the days).
