Phelps won some races by ridiculously large margins, others with the closest of finishes -- most memorably, his seventh gold by one-hundredth of a second over Serbia's Milorad Cavic in the 100 fly.
What fantastic Olympic action!
For many of us, an even more exciting and awe-inspiring performance was that of the Jamaican sprinter Usain Bolt. The lead he took and ease with which he won the race, setting a new world record along the way, was just phenomenal. The New York Times has the story.
