"Oh, yeah, sub-11 is always fun," Madison said.
Allyson Felix finished in 11.01, but that was good enough to win her heat, and Veronica Campbell-Brown, who has beaten Felix in the last two Olympic 200s, won her 100 heat in 10.94.
All these fast times left sprinters such as Melissa Breen of Australia on the outside looking in. In 2008, her time of 11.34 seconds would have easily moved her out of the first round and might have gotten her into the semifinals, as well. On this day, she was one-and-done, but impressed by what she saw.
"Those girls," Breen said, "are ridiculously fast."
