Flora Duffy achieved instant national hero status when she won Bermuda’s first-ever Olympic gold medal on Tuesday after delivering a dominant run leg for an emphatic victory in the women’s triathlon on a stormy Tokyo course.

Duffy, 33, was part of a group of seven who broke clear at the start of the 40km bike but then stamped her authority on the race with a fantastic performance over the 10km run to finish in one hour, 53.36 minutes.

Briton Georgia Taylor-Brown overcame a flat tyre near the end of the bike leg to chase back strongly and finish second, 74 seconds behind, bagging another silver for Britain after Alex Yee's in the men's race on Monday. Katie Zaferes, world champion in 2019, won bronze for the United States.

The victory, in her fourth Olympics, caps a wonderful career for Duffy, as she becomes her country's second Olympic medallist after Clarence Hill took a heavyweight boxing bronze in 1976.

Duffy hailed the victory as "an incredible moment" and as Bermuda became the least populous nation to win a summer Olympic gold, its Premier David Burt sent his congratulations over Twitter, saying: "You've worked so hard and you've made an entire island proud!"

Battle of the record breakers looms in the Tokyo pool

Tuesday’s women’s 100m backstroke final will be a battle of the record breakers with Australia’s Kaylee McKeown going for gold against American Regan Smith and Canada’s Kylie Masse.

The trio are the three fastest swimmers in the history of the event, all having held the world record, with McKeown the current owner.

In the women’s 100m breaststroke, American Lilly King faces a tough challenge to the defence of her title with South African Tatjana Schoenmaker in the prime lane four after qualifying fastest.

World record holder King’s old Russian foe Yulia Efimova is also in the final.

The men’s 100m backstroke features defending champion and world record holder Ryan Murphy of the United States going for a fourth career gold with Russian Kliment Kolesnikov looking dangerous and Australian Mitch Larkin also a threat.

The first final of the morning is the men’s 200m freestyle with Britain’s Duncan Scott and Tom Dean hoping to medal and American Kieran Smith in the lane between them.

Team USA athletes in action on day 4 of Tokyo 2020

All eyes will be on American artistic gymnast and four-time Olympic gold medallist Simone Biles and her US teammates as the team final takes place inside Ariake Gymnastics Centre for Tokyo 2020.

The squad finished in a surprising second place to the ROC team in qualifying after a series of rare mistakes set them back.

The US women won gold at each of Rio 2016 and London 2012.

Elsewhere, it's an Olympic re-match for softball as the U.S. faces Japan - though the sport hasn't been in the Olympic programme since Beijing 2008, when the Japanese beat the Americans in the Beijing final.

Team USA edged Japan in group play on Monday in what was a preview of the gold-medal bout.

Weightlifting day 5: Shi Zhiyong returns to action and aims for gold in men's 73kg

The action gets underway at 13:50 (local time) with athletes battling it out in the qualification rounds before a new Olympic champion gets to be crowned in the finals.

Rio 2016 (69kg) gold medallist Shi Zhiyong, from China, returns to action on the Olympic stage and is looking to get his second title in the 73kg. But favourite Miyamoto Masanori, who exceeded Shi's 73kg clean and jerk world record in 2019, and Bozhidar Andreev of Bulgaria are sure to put up a fight for the coveted crown.

Judo day 5: Women's -70kg and men's -90kg medals decided today

The morning session of Day 5 of the Tokyo 2020 judo competition begins with the women's -70kg elimination rounds, followed by the quarterfinals. The men's -90kg follows on in the same structure as the women's event.

The evening session features the same weight classes, this time with the women's repechage then semifinals, followed by the men. The women's -70kg bronze-medal contest is followed by the final, which decides gold and silver, with the -90kg men's event concluding the day.

With all of Rio's women's -70kg medallists retired or not competing, the floor is open to fresh faces and a new champion in Tokyo. The Netherlands' Sanne van Dijke comes into these Games on the back of a silver-medal performance at the 2020 European Judo Championships, while two-time World Champion Chizuru Arai, who swept golds at the IJF Grand Slam, will be hoping to win more gold on home turf.

With Mashu Baker not in Tokyo for the men's -90kg, the floor is open for another new Olympic champion. World champion Nikoloz Sherazadishvili, Ivan Felipe Silva Morales (of Cuba) and Korea Republic's Rio 2016 bronze winner Donghan Gwak will be hoping to win that gold on offer.

Fencing day 5: Men's Sabre Team gold to be handed out for first time since 2012

It's the fifth day of the fencing competition at the Tokyo 2020 Games and the action starts at 10am (local time) at the Makuhari Messe Hall B in Chiba Prefecture. The quarterfinals will be followed by the semifinals of the Men's Sabre Team event in the first section to the competition.

The evening session gets underway from 18:30 with the all-important bronze and gold-medal matches.

The Men's Sabre Team event is back in the Olympic programme for the first time since London 2012. The reigning Olympic champions, Republic of Korea, will be the favourites going into the competition, having won the last three World Championships in the event. But Hungary and Italy are also strong nations and each team will be looking to continue that success.

Equestrian day 4: Germany's Isabell Werth aims for first Dressage Individual Grand Prix Freestyle gold in 25 years

It's the fourth day of the equestrian competition at Tokyo 2020, and the action starts at 17:30 (local) at the Equestrian Park in Tokyo. The top 18 riders, who advanced from the rounds on 24 and 25 July, will compete in the finals of the Dressage Individual Grand Prix Freestyle.

German dressage extraordinaire Isabell Werth (Bella Rose 2) is the resounding favourite in the individual dressage after scoring 82.500 in the individual qualifier at the Equestrian Park on Sunday.

Werth will be looking to win the Olympic gold medal in the individual dressage 25 years after she clinched the title for the first time in Atlanta 1996.

Compatriot Jessica von Bredow-Werndl will also be in the running after earning the second-highest score in qualifying.

Great Britain's Charlotte Dujardin, who has won back-to-back individual dressage gold medals in London 2012 and Rio 2016, will be in the mix to challenge for a third consecutive title.

Diving day 4: Brits Jack Laugher and Dan Goodfellow in the 3m springboard synchro event

Day four of the diving competition sees the fourth medal event of these Olympics, the men's synchronised 3m springboard.

One half of the defending champion duo, Jack Laugher, is returning to try and repeat his Rio 2016 synchronised 3m springboard title, this time alongside fellow Brit Daniel Goodfellow. Previous partner Chris Mears retired to become a music producer.

China won seven out of the eight gold medals on offer at Rio 2016, with only Laugher and Mears' gold in this event breaking that run. China will be looking to put that right this time out in Tokyo.

Road cycling day 3: Dutch take on the rest of the world in individual time trial

The day’s action will start with the women’s event that will be held over 21.1 kilometres. Riders will compete along an undulating 21.1km loop in and around the speedway, with Mount Fuji set as the backdrop for the events.

The men will cover double the distance completing two laps of the circuit for a total of 44.2km. Unlike a road race where everyone starts at the same time, the event sees one rider race against the clock to test their individual power.

In the women’s race, versatile U.S. rider Chloe Dygert will be among the favourites to challenge for the gold medal. She will have a mountain to climb against a classy Dutch team led by Rio 2016 bronze medallist Anna van der Breggen and two-time world time trial champion Annemiek van Vleuten.

Dygert is coached by Kristin Armstrong, who won an unprecedented three consecutive Olympic time trial titles.

The Dutch has an equally strong challenger in the men’s race with former world champion and Rio 2016 silver medallist Tom Dumoulin leading the charge. Double world champion Rohan Dennis of Australia will also be among the top challengers.
