London, Aug. 3 (BBC): New Zealand's sprint canoeist Lisa Carrington showed her class with two quick golds on day 11 at Tokyo 2020.

The 32-year-old from Auckland claimed her third consecutive K1 200m sprint Olympic title, then teamed up with Caitlin Regal to win the K2 500m event.

In one of the stories of the Games, Norway's Karsten Warholm won men's 400m hurdles gold with a new world record.

Germany's world champion Malaika Mihambo produced a huge final jump of 7.00m to take women's long jump gold.

Later on day 11, four-time Olympic gymnastics champion Simone Biles is set to return to action in the women's balance beam final, where she will be competing against fellow American Sunisa Lee.

Biles, 24, withdrew from four finals to prioritise her mental health.

'Warholm is Superman'

Norway's Warholm ran a stunning men's 400m hurdles race to slash more than 0.7 seconds off his old world record. His time of 45.94 seconds won a final described as "truly unbelievable" by British former hurdler Colin Jackson.

Former 1500m Olympic silver medallist Steve Cram, watching Warholm's celebration, said: "No wonder he rips his shirt apart - he is Superman in this event!"

Warholm, who now holds the European, world and Olympic titles, told BBC Sport: "You know the cliche that it hasn't sunk in yet? I don't think it has but I feel ecstatic."

Two-time world 110m hurdles champion Jackson told BBC TV that Warholm's performance could be compared with those of Olympic sprinting greats Usain Bolt and Florence Griffith-Joyner.

He said: "When you talk about world records, this is up there with Usain Bolt's time of 9.58 seconds in the 100m and up there with Flo Jo's 10.49 seconds in the 100m."

In the women's long jump, Germany's Mihambo trailed to American Brittney Reese for much of the event.

But with her final jump, the reigning world champion hit the 7.00m mark to leave Reese, the 2012 Olympic champion, with a silver - the same medal she won at Rio 2016. Nigeria's Ese Brume was third.

Carrington dominates on water

New Zealand sprint canoeist Carrington maintained her fine Olympic record by claiming two golds on Tuesday.

She continued her dominance of the K1 200m sprint, setting a new Olympic best to beat Spain's Teresa Portela by 0.763 seconds, before joining up with Regal to take K2 500m gold.

Carrington starts her bid for another gold on Wednesday in the K1 500m.

Elsewhere, boxer Sena Irie created history by becoming the first Japanese woman to win Olympic boxing gold, beating Nesthy Petecio, the 2019 world champion, of the Philippines.

The USA remain on course for success in men's basketball, although they had to come from 11 points down to beat Spain 95-81 in their quarter-final.

But India's hopes of reaching a first hockey final since 1980 were ended as their men were beaten 5-2 by Belgium in their semi-final.
