Beijing, China, August 8, 2008—Fireworks light up the sky over the Beijing National Stadium—also known as the Bird's Nest—during the 2008 Summer Olympics opening ceremony.

China kicked off the 29th Olympic Games with a colorful celebration of its ancient history and modern might. The event—which drew crowds of around 91,000—featured a 50-minute spectacle with 15,000 performers, an array of fireworks, and ancient drum playing, the Agence France-Presse news service reported.

Over the next 16 days, approximately 10,000 Olympic athletes representing 205 countries will compete in events ranging from archery to fencing to sailing.

In anticipation of hot, smog-choked Beijing, many athletes engaged in special training techniques to keep on top of their game.
