• Best event: 200 breaststroke
The 30-year-old is vying for her fifth Olympic bid. She didn’t medal at the 2008 Summer Games, but owns two golds, four silvers and a bronze from her previous three trips. Tough fields in both the 200 and 100 breaststrokes at the Trials — led by Rebecca Soni — will leave her with some work to do. Beard hasn’t ruled out sticking around for 2016, saying it might just fuel another bid if she doesn’t make this 2012 U.S. team.
At the 1972 Munich Games, Steve Genter suffered a collapsed lung days before his event. Swimming without the consent of his doctors, he won a silver medal in the 200-meter freestyle and bronze in the 400 freestyle.
