more than 10,000 athletes
According to NBC 551 ( and more)
There were 595 athletes at the opening ceremony. But I'm unsure as to how many more there are competing that didn't go.

There are more foot injuries in olympic athletes who go barefoot, and they have more problems with traction.
Generally there are more spectators than athletes.
The USA has 530 athletes and only the host country with 541 has more

In Paris in 1900 the games were part of the World's Fair and many athletes and spectators never realised that the competitions they were competing in or watching were the Olympics(it was only the second one). Some of the athletes died many years later still not knowing.
