It’s been another successful day for Britain in Tokyo, with success across sailing, athletics and a historic result in skateboarding.

GiveMeSport Women recaps the biggest news from overnight, what to look forward to today and which Team GB stars are in action later.

What happened overnight at the Tokyo 2020 Olympics?

Sydney McLaughlin breaks 400m world record

The USA’s Sydney McLaughlin stormed to gold in the women’s 400m hurdles, smashing her own world record in the process.

The 21-year-old finished in 51.46 seconds –– almost half a second quicker than the 51.90 she set at the US trials in June.

Defending Olympic champion Dalilah Muhammed was leading for much of the race but could only claim silver.

Speaking after breaking the world record, McLaughlin said: “I can’t really get it straight in my head yet. I’m sure I’ll process it and celebrate later.”

Sky Brown becomes GB’s youngest ever Olympic medal winner

13-year-old Sky Brown became Britain’s youngest ever Olympic medallist after winning bronze in the women’s park skateboarding final.

Japan’s Sakura Yosozumi claimed gold with a score of 60.09 points, while 12-year-old compatriot Kokona Hiraki finished second.

Brown overtakes Sarah Hardcastle as Britain’s youngest medallist at the Games. The swimmer was 15 years and 113 days when she won silver and bronze at the 1984 Olympics in Los Angeles.

“This is incredible –– it feels unreal,” Brown said after the event. “I’m so happy to be here –– I’m blessed.”

Hannah Mills becomes most successful female sailor in Olympic history

Team GB’s Hannah Mills became the most successful female sailor in Olympic history as she and Eilidh McIntyre won 470 gold at Tokyo 2020.

The pair finished fifth in the medal race but had done enough in earlier performances to hold off Poland and France, who claimed silver and bronze respectively.

Mills won silver at London in 2012 and followed up with gold in the same class at Rio in 2016.

McIntyre, meanwhile, follows in the footsteps of her father, Mike, who won gold in the star class at the Seoul Olympics in 1988.

Great Britain thrashed by the Netherlands in hockey semi-final

Reigning Olympic women’s hockey champions Great Britain will not retain their title this year following a 5-1 defeat to the Netherlands in the semi-finals at Tokyo 2020.

Team GB had already lost to the Dutch in this tournament, losing 1-0 in the pool stages, but were comprehensively thrashed this time round in a repeat of the 2016 final.

Great Britain will now challenge for a bronze medal on Friday at 02:30 BST.

Tamyra Mensah-Stock becomes first black wrestling gold medallist

America’s Tamyra Mensah-Stock made history in the women’s freestyle 68kg wrestling final as she became the first black woman to win an Olympic gold medal in the sport.

Mensah-Stock beat Nigeria’s Blessing Oborududu 4-1 in the final, while Ukraine’s Alla Cherksasova and Kyrgyzstan’s Meerim Zhumanazarova both claimed bronze.

Speaking after her win, Mensah-Stock said: “I knew I could do it. I knew it would be really hard. I prayed I could do it. In my wildest dreams, I knew I could do it.”

What’s coming up at the Tokyo 2020 Olympics?

Athletics
