IBTIHAJ MUHAMMAD

The Olympic fencer made history as the first U.S. woman to compete (and later, medal) at the Olympics wearing a hijab. "For me, this is just who I am," Muhammad told PEOPLE. "Growing up a Muslim and a girl, I always had to change my uniform [for athletics] … My parents were in search of a sport for me where the athletes wore long pants and long jackets – that's how we stumbled upon fencing." She added, "I want people to see Muslims in a positive light."

After winning gold in the event finals for vault, Biles became the most-decorated American gymnast ever, male or female, with 17 medals in Olympic and world championship competitions. At Rio, she won gold in the team all-around competition and gold in the individual all-around, vault and floor routine, and took bronze in the beam.

KATIE LEDECKY

The American swimmer finished Rio on a high note, breaking her world record in the 800-meter freestyle – she now holds the 13 fastest times ever in that event. Another milestone? She's the first woman to win the 200-, 400- and 800-meter freestyle races since Debbie Meyer at the 1968 Mexico City games. Ledecky won a total of five medals at the Rio Olympics – gold medals for the 200-, 400- and 800-meter freestyles and the 4x200-meter freestyle relay, and silver for the 4x100-meter freestyle relay.

USAIN BOLT

Bolt won his third straight gold medal in the 200-meter sprint – the first ever runner to do that. Yet he still wasn't satisfied with his performance: "I'm always happy for the win, but I wanted a faster time," Bolt told NBC. "I felt good, but when I came into the straight, my body wouldn't respond to me. So I guess it's just age and all-around just taking a toll." (He's 29, for the record.)

The 21-year-old player ensured that she'll be getting at least a silver medal when she won the semifinals of the women's singles, which means she's made history – no Indian female player before her has won better than a bronze medal at the Olympics.
