Surfing is set to make its highly anticipated Olympic debut in Tokyo. The competition window opens on Day 2 for both the men's and women's competitions but runs through Day 9, so the conditions will dictate when the competition rounds actually take place.

In Round 1 of each competition, 20 surfers will be split into five heats of four athletes based on world rankings. The top two from each heat will advance directly to Round 3, while the bottom two will duke it out in Round 2 for another shot to advance. 

Two-time world champion John John Florence and three-time world champ Carissa Moore, both from Hawaii, highlight the U.S. contingent, with Moore one of the favorites for gold in the women's event.

Alix Klineman and April Ross begin their Olympic campaign with a match against Chen Xue and Xinxin Wang of China. Ross won a silver medal at London 2012 playing with Jen Kessy and then a bronze medal at Rio 2016 playing alongside Kerri Walsh Jennings. Klineman, a former indoor volleyball player, will be her third different Olympic partner. Ross and Klineman are one of the world's top-ranked teams and are expected to contend for gold. (Walsh Jennings, who teamed up with Brooke Sweat during this Olympic cycle, did not qualify for Tokyo.)

Another U.S. team in action on Day 2 is the freshly formed duo of Jake Gibb and Tri Bourne. Gibb was originally teamed with Taylor Crabb, but Crabb was replaced with Bourne after a positive COVID test earlier this week.

Skateboarding makes its Olympic debut tonight with both rounds of the men's street contest. The event will start with 20 skaters in the prelim, and then the field will be narrowed down to eight for the final. In both rounds of competition, riders will take two 45-second runs and attempt five individual tricks. The contest will be scored by a panel of judges to decide the winner.

U.S. skater Nyjah Huston has dominated the contest scene for years and is the favorite for gold, but Japan's Yuto Horigome is also in the mix. Huston and Horigome have frequently traded places on the top two steps of the podium at major contests in recent years.

A dual star in both road and track cycling, this will be the first of three events for her in Tokyo.

The United States is hunting for a fourth straight gold medal in men's basketball but raised some questions after losing exhibition matches to Nigeria and Australia earlier this month. The question remains: Were those shaky performances a sign of vulnerability for this U.S. squad, or just the result of a new team trying to gel together quickly? The team has also dealt with needing to replace players due to injury (Kevin Love) and COVID (Bradley Beal).

The U.S. team is coached by Gregg Popovich and led by Brooklyn Nets star Kevin Durant. Devin Booker of the Phoenix Suns and Khris Middleton and Jrue Holiday of the Milwaukee Bucks have joined the team after quickly taking flights over to Tokyo following the end of the NBA Finals.

France will present a tough test for Team USA's opening game. The French team includes five NBA players, most notably star Utah Jazz center Rudy Gobert.
