Swimming: Onto the men’s 200m freestyle final...

2.43am BST

Swimming: We’re in for a blockbuster 200m freestyle final. Katie Ledecky saw what Ariarne Titmus accomplished in her first semi and laid down a marker, leading from the front to win in 1.55.34. Barbora Seemanová (CZE) finished second, Italy’s incredible champion Federica Pellegrini powered home at the death to snatch third, beating out Maddy Wilson (AUS) and 14-year-old Summer McIntosh (CAN).

Wilson’s time was good enough to sneak into the final in eighth spot, but all eyes will be on another Titmus v Ledecky duel in the pool.

An update from the hockey stadium: Team GB have secured their second win the tournament, running out 3-1 winners over underdogs Canada after a nervous start. “You have to understand when you’re playing teams that rank lower than you, they have nothing to lose. It’s a win-win for them,” said the team’s head coach Danny Kerry.

Not strictly speaking to do with the Olympics, but very much related given Paralympian Olivia Breen’s recent experience of being told what to wear, but remember the Norwegian beach handball team that was fined in a “case of improper clothing” for refusing to wear bikini bottoms during a tournament in Europe? The protest against what the team described as “very sexist” uniform rules cost them $1,500. But they might not have to fork out themselves after pop star P!nk showed her support for their cause.

I’m VERY proud of the Norwegian female beach handball team FOR PROTESTING THE VERY SEXIST RULES ABOUT THEIR “uniform”. The European handball federation SHOULD BE FINED FOR SEXISM. Good on ya, ladies. I’ll be happy to pay your fines for you. Keep it up.

The gold medallist for women’s taekwondo, the American Anastasija Zolotic said she hoped her historic win would give taekwondo a boost in her home country, where it has struggled to gain traction in a par with boxing or mixed martial arts. The 18-year-old sprung a surprise to win the USA’s first gold medal for women in taekwondo since it became a full-medal Olympic sport in 2000.

“I work my butt off for it, and I hope taekwondo [becomes] as popular as it can be in the US,” Zolotic said. “Hopefully in 2024 if I make it over there and win another gold medal and just keep grinding to LA [in 2028], by then taekwondo will be all over the map. Hopefully [my win] will give it a better image than it has and bring it back up to where USA taekwondo deserves to be - one of the best sports that you can watch,” she said.

Some cycling news: the men’s road race takes place at 3am BST, 11am local time on Saturday, but one man who won’t be at the start line is Simon Geschke, after the German rider tested positive for Covid-19.

Geschke, who was set to be part of a four-man German team, had been staying away from the Olympic village with a group of other cyclists, all of who have initially tested negative for Covid.
