Schedule: Women's 200m freestyle: heats, July 30; semifinals, July 30; final, July 31 Women's 400m freestyle: heats, July 29; final, July 29 Women's 4x100m freestyle relay: heats, July 28; final, July 28 Women's 4x200m freestyle relay: heats, Aug. 1; final, Aug. 1
Olympic experience: This is her second Olympics. She won a bronze medal in the 4 x 200-meter freestyle relay in 2008, and broke her own American record in the 200-meter freestyle at the Olympic trials in Omaha, Neb. in June.
What to expect: She's scheduled to swim in four events (two individual and two relays), and has a chance to medal in all of them.
Quotable: "I can remember when I was in high school, coming in seventh and eighth at our state meet."
Katie Ledecky
Age: 15
From: Bethesda
Schedule: Women's 800m freestyle: heats, Aug. 2; final, Aug. 3
Olympic experience: A rising sophomore at Bethesda's Stone Ridge School of the Sacred Heart, Ledecky is the youngest member of the 2012 U.S. Olympic team. She placed first in the 800-meter freestyle at the Olympic trials, beating second-place finisher Kate Ziegler by more than two seconds.
What to expect: If Ledecky can replicate her Olympic trials performance in London, she could have a chance to reach the podium.
Quotable: "Four years ago I never knew how to qualify for an Olympics trials."
Bob Bowman (assistant coach)
Age: 46
From: Columbia, S.C.
Olympic experience: Bowman, CEO of North Baltimore Aquatic Club, has coached Phelps in the past three Olympics. This will be his second Olympics as an official staff member with the U.S. team.
What to expect: Bowman will work primarily with Phelps, who could win seven gold medals in London.
Quotable: "Michael is focused on his preparation for London. His performance record over his career speaks for itself."
Track and field
Matthew Centrowitz
Age: 22
From: Arnold
Schedule: Men's 1,500m: round 1, Aug. 3; semifinals, Aug. 5; final, Aug. 7
Olympic experience: This is Centrowitz's first Olympics. He was a seven-time All-American and three-time Pac-10 champion in the 1,500-meter race at Oregon.
What to expect: Centrowitz could become the first American to earn a medal in the 1,500 since Jim Ryun claimed silver in 1968. He earned bronze at the 2011 world championships.
Quotable: "This is my first Olympic team, so I'm very excited to represent the United States in the Olympics on the biggest stage for track and field."
Julie Culley
Age: 30
From: Lebanon, N.J.; former Loyola track coach
Schedule: Women's 5,000m: round 1, Aug. 7; final, Aug. 10
Olympic experience: This will be Culley's first Olympics. She won the 5,000-meter event at the Olympic trials with a personal-best 15:13.77.
What to expect: Culley, an assistant coach at Loyola, should have a legitimate shot at claiming a medal. That would be a major boon for a women's team that didn't have a single member finish in the top eight in the 5,000 in Beijing.
Quotable: "You can't overbuild it, and that was the biggest thing I had really to keep in mind going into the Olympic trials," Culley told The (Lehigh Valley, Pa.) Express-Times. "If you think too hard about how big that stage is, it starts to become overwhelming."
Andrew Valmon (coach)
Age: 47
From: Brooklyn, N.Y.; Maryland coach
Olympic experience: This is Valmon's first time coaching the U.S. men's track and field team in the Olympics. A two-time Olympic gold medalist, Valmon served as a Team USA assistant at the 2009 world outdoor championships in Berlin. He was also the head coach for the 2010 world indoor championships team in Doha, Qatar.
What to expect: Valmon, whose Maryland women's track and field team was recently cut, hopes to help a U.S. men's team rebound from a disappointing 2008 Olympics. The U.S. track program has a decent chance to achieve its goal of 30 medals -- seven more than it claimed in Beijing.
Quotable: "Any time you get the opportunity to coach Team USA, you're not going to turn it down," Valmon told The Diamondback. "There's really no better reward for someone in my position."
Windsurfing
Farrah Hall
Age: 30
From: Cape St. Claire
Schedule: Women's RS-X: race 1, July 31; race 2, July 31; race 3, Aug. 1; race 4, Aug. 1; race 5, Aug. 2; race 6, Aug. 2; race 7, Aug. 4; race 8, Aug. 4; race 9, Aug. 5; race 10, Aug. 5; medal race, Aug. 7
Olympic experience: After narrowly missing the Summer Games four years ago, Hall earned a trip to London when she finished 40th overall at worlds last March.
What to expect: Hall doesn't expect to win a medal in London, and is hoping for a top-10 finish. Asian and European countries tend to dominate windsurfing at the Olympics.
Quotable: "This a sport that you have to make a commitment to for almost a decade to sort of get anywhere. It's taken me six years to build a program, to make mistakes and correct mistakes, and have something I am happy with."
