The first full day of competition for the 2016 Rio Summer Olympics was held this past Saturday, August 6th. The weekend was full of memorable moments and created a great start for the rest of the games. Here are some of the highlights and upsets from the first weekend.

The Star-Spangled Banner was the first national anthem to be played at a Rio podium ceremony thanks to U.S. teen Ginny Thrasher of Virginia. She won the 10-meter air rifle competition for women, beating Du Li of China by just one point.

The world empathized with Frenchmen Samir Ait Said after he broke his leg as he tried to land his vault on the first day of men’s gymnastics at Rio. He had also missed the 2012 Olympic Games due to breaking his other leg at the European Championships. His spirit remained undiminished and told fans quickly after that he was planning to return for the next Olympics.
Of all the sports played at the Olympics, nothing was more emblematic of Brazil than beach volleyball. The fans went wild as Brazil won the gold, and many expect more to come in the following week.

The biggest upset of the weekend came on the tennis courts where four-time gold medalist Venus Williams was defeated by Kirsten Flipkens of Belgium, the 62nd-ranked player in the world. Williams, who at 36 is likely in her final Olympics, still had another chance at one more gold medal as she teamed up with her sister, Serena, in doubles. Unfortunately, the three-time Olympic doubles champions lost for the first time in the Olympics. Lucie Šafářová and Barbora Strýcová of the Czech Republic dominated the Williams sisters from the start, winning 6-3, 6-4 in straight sets.

On Sunday, all eyes were on the swimming competitions. American Katie Ledecky, only 19, obliterated her own world record in the women’s 400-meter freestyle by almost two seconds. Ledecky also holds the world-record in the 400, 800 and 1,500 freestyle events. She will most likely be the new face of U.S. swimming once Michael Phelps retires from his career.

Phelps earned yet another gold medal on Sunday after he swam the second leg of the 4×100 freestyle, giving the Americans a lead they wouldn’t relinquish. Phelps now holds 19 gold medals and a total of 23 medals overall.

On Monday, Ibtihaj Muhammad became the first U.S. athlete to wear a hijab during the Olympics. The Muslim-American fencer made history sporting her hijab, but was eliminated in her second bout in the women’s sabre tournament. Muhammad won 15-13 over Olena Kravatska of Ukraine in the opening bout Monday morning but later lost to Cecilia Berder of France 15-12. The New Jersey native was proud of her ability to compete in the Olympics and give the USA and opportunity to be more diverse.

The gymnastics qualifying rounds for the all-around final began this weekend, with many spectacular performances. Aly Raisman of Team U.S.A dominated her qualifying round on the uneven bars, one of her weakest events. Though her performance was exhilarating, all eyes remained on Aly Raisman’s parents. First noticed at the London Games, Lynn and Rick Raisman put every gut-wrenching emotion on display from the sidelines. The 22-year-old gymnast already has two Olympic medals but that didn’t stop her parents from grabbing onto one another and squirming with nervousness before jumping up to applaud the routine.

Gymnast Oksana Chusovitina was another star athlete this weekend. At 41-years-old, the olympian is making history cometing at her 7th Olympic games and is the oldest woman to have done so, ever. She has a 17-year-old son, the same age as many of the women Chusovitina is competing against. However, she’s proven she’s here to win. She earned a score of 14.999 on the vault representing Uzbekistan. Chusovitina competed in her first games at the 1992 Olympics held in Barcelona.

Though a crazy and thrilling first few days of the Olympics, there is still much more to come as the athletes take center stage.
