On Saturday (03, August) at the Paris Olympics, Sha'Carri Richardson competes for the women's 100m title, while Simone Biles seeks her third gold medal. Meanwhile, an Algerian boxer embroiled in a gender controversy returns to the ring.

In swimming, Katie Ledecky, now the most decorated US woman Olympian, aims to add the 800m freestyle gold to her 1500m title.

On the clay courts of Roland Garros, Zheng Qinwen faces Donna Vekic for a chance to win China's first tennis singles gold.

Richardson, a flamboyant US track star and reigning world champion in the 100m, holds the fastest time this year at 10.71 seconds. The 24-year-old Texan, aiming to become the first American since Gail Devers in 1996 to win Olympic 100m gold, smoothly advanced through Friday's heat with a time of 10.94 seconds. Competing in Paris three years after her Olympic hopes in Tokyo were dashed by a positive marijuana test, Richardson's main rival is Saint Lucia's Julien Alfred. Marie-Josee Ta Lou-Smith posted the fastest heat time of 10.87 seconds, with Jamaica's Shelly-Ann Fraser-Pryce, a two-time 100m gold medalist, also competing.

The 100m semi-finals and final are scheduled for Saturday evening.

Richardson expressed her excitement: "To be an athlete here, competing with the energy, with a great appreciation for track and field, it gives great support to be a track and field athlete. So I'm super-excited to compete on the Olympic stage."

Saturday's athletics also feature the women's triple jump, men's shot put, and the conclusion of the men's decathlon.

After her difficult experience in Tokyo, where she withdrew from several events due to the "twisties," Simone Biles already has two golds in Paris. The 27-year-old, who has won team gold and the all-around title, now focuses on the vault final against defending champion Rebeca Andrade of Brazil.

Biles acknowledged Andrade's challenge: "I don't want to compete with Rebeca no more. I'm tired! It's way too close."

Two boxers in Paris are caught in a gender controversy. Taiwan's Lin Yu-ting won her opening bout on Friday, and Algeria's Imane Khelif returns to the ring on Saturday after a 46-second opening win. Both fighters were disqualified from the 2023 world championships, run by the International Boxing Association (IBA), for failing to meet "eligibility criteria." The International Olympic Committee (IOC) has cleared them to compete in Paris, sparking debate. Hungarian boxer Anna Luca Hamori, who faces Khelif, expressed her concern on Facebook: "In my humble opinion, I don't think it's fair that this contestant can compete in the women's category."

Katie Ledecky, 27, who won the 1500m freestyle title on Wednesday, seeks her fourth consecutive 800m title. Australia's Ariarne Titmus is her main competitor.

Rising star Summer McIntosh targets her third gold in the women's 200m medley. The Canadian teenager has already secured golds in the 200m butterfly and 400m medley, along with a silver in the 400m freestyle.

Zheng Qinwen, who defeated four-time French Open champion Iga Swiatek in the women's singles semi-finals, aims to make history for China. She faces Croatia's Vekic on the same court where her inspiration, Li Na, became China's first Grand Slam champion 13 years ago.

Saturday also features the men's cycling road race, with top competitors like Dutch world champion Mathieu van der Poel, Paris Olympics time trial champion Remco Evenepoel, and Belgian Wout van Aert.
