As the Parisian sun rises on day three of the Olympics, there are 19 gold medals up for grabs.
Australian swimming, boxing, hockey and basketball fans will have reason to be watching overnight, while the men's skateboarding heats will finally start after a two-delay delay because of rain.
Here's what's happening on day three.
Star swimmers face off
The women's 200m freestyle final is shaping up as the mother of all club meets between training partners Ariarne Titmus and Mollie O'Callaghan. Titmus broke O'Callaghan's world record six weeks ago.
Titmus and O'Callaghan both cruised into Monday night's 200m freestyle final as the top-two qualifiers.
Titmus won narrowly ahead of O'Callaghan but said the result wasn't significant.
"You always want to be in the middle of the pool in a final and get yourself in a good position," she said.
"But that was really the only plan for tonight, I tried to conserve as much as I could."
Titmus touched in one minute 54.64 seconds, six-hundredths of a second quicker than O'Callaghan.
Max Giuliani will be competing in the men's 200m freestyle final.
The Olympic debutant was fifth-fastest in the semis to reach the final.
Meanwhile Ella Ramsay and Jenna Forrester will compete in the women's individual medley final.
Diving: 10m platform final
World individual champion Cassiel Rousseau will combine with Domonic Bedggood in the 10m synchronised platform, with British flag bearer Tom Daley and Noah Williams also competing.

The tears flowed after the shattered pair delivered a shocking fifth and final effort in the women's synchronised 3m springboard event on Saturday.
It dropped them from third to fifth, just when it seemed they were set to even grab silver on the opening afternoon of the Games at the Paris Aquatics Centre.
What else is happening?
The Opals women's basketball team open their Paris campaign with a pool game against Nigeria. The powerful American women's team, aiming for their 10th gold medal, play Japan.
Meanwhile, the women's rugby 7s team will play their quarter-final.
Tokyo bronze medallist Harry Garside (63.5kg) leads the Australian hopes in boxing and starts his competition, with Teremoana Teremoana (+92kg) and Tyla McDonald (60kg) also having bouts on Monday.
The Kookaburras continue their men's hockey campaign against Ireland.
The first gymnastics medals will be decided in the men's teams, with China and Japan the key favourites.
Multi-talented British cyclist Tom Pidcock will aim to repeat his Tokyo gold medal in mountain biking, although Swiss legend Nino Schurter is certain to challenge him.
