Who is representing the United States?

A total of 613 athletes are scheduled to represent the United States at the Tokyo Olympics. Among the large contingent are several athletes who are expected to challenge for gold in one or multiple events.
Simone Biles, already the most decorated American gymnast of all time, will be looking to defend her title and add to the four gold medals she won at the 2016 Rio Olympics. Swimmer Katie Ledecky, a five-time gold medal winner, is a favorite to win again in at least four events. Caeleb Dressel, Simone Manuel and Lilly King also will be in the hunt for swimming gold.
Allyson Felix, the most recognizable U.S. track and field athlete, qualified for her fifth Olympics and is among the favorites in the 400 meters. Sydney McLaughlin (400-meter hurdles), Grant Holloway (110-meter hurdles), Noah Lyles (200 meters) and Erriyon Knighton (200 meters) are also among the big names to watch on the track.
Here’s a look at the athletes along with their respective competition schedules. Included on this list are reserves who could see competition at the Games.
Who isn’t competing in Tokyo?

Several high-profile American athletes, including former gold medalists, will not take part in the Tokyo Olympics. Among them are 23-time major tennis champion Serena Williams and Lakers stars LeBron James and Anthony Davis, all of whom opted out from competing. Kerri Walsh Jennings, a three-time Olympic gold medalist in beach volleyball, missed out on a sixth Games after she and teammate Brooke Sweat failed to qualify.
Five-time Olympic medalist sprinter Justin Gatlin failed to make the cut for Tokyo. Sprinter Sha’Carri Richardson, who won the women’s 100 meters at the U.S. track and field trials last month, will not compete because of her 30-day suspension after a positive marijuana test. Men’s basketball player Bradley Beal was forced to leave the team after being placed in health and safety protocol last week, and 2012 gold medalist Kevin Love withdrew from the team as he continues to recover from a right calf injury. Tennis player Coco Gauff will not compete after testing positive for the coronavirus.
Southern California native Kim Rhode, a six-time medal winner in shooting, didn’t qualify for her seventh Olympics. Laurie Hernandez, who won gold with the U.S. gymnastics team at the 2016 Rio Olympics, failed to qualify because of a knee injury.
In addition, the United States will not be competing in five sports — men’s soccer, men’s three-on-three basketball, women’s badminton, field hockey and handball.
