SIFAN HASSAN

Fred Kerley led the first American sweep of the 100 meters at the worlds in 31 years, barely edging teammates Marvin Bracy and Trayvon Bromell to stamp a red-white-and-blue exclamation point on the first championships ever held in the United States.

Over nine days at the near-empty Olympic Stadium, the women of track and field delivered a memorable show.

Despite running three races in the last few days, Hassan found a higher gear before the final turn to surge past world-record holder Letesenbet Gidey of Ethiopia and cross the line in 29:55.32.

Marcell Jacobs backed up his shocking 100-meter victory with another totally unexpected gold for Italy in the 4x100-meter relay at the Olympics.

Faith Kipyegon of Kenya repeated as Olympic 1500m champion while Dutchwoman Sifan Hassan's bid to triple in the 5000m, 1500m and 10,000m came to an end at its penultimate stage.

Defending Olympic champion Faith Kipyegon won the first semifinal in an astonishing 3:56.80, the fourth-fastest time run in Olympic history.

No runner has ever won the 5,000m, 1,500m, and 10,000m treble at the same Olympics. But there have been other memorable distance triples and doubles.

In what might be the first step towards an unprecedented triple, the Dutch runner won two races on the same day

Sifan Hassan is going for it: three gold medals in three races. She's already won gold in one of them — the women's 5,000 meter race.

Netherlands' Sifan Hassan completed the first of her three Olympic gold-medal attempts – the 1500m and 10,000m are up next.

The quest for gold medals is on track for the U.S. women’s basketball and volleyball teams after finishing at the top of their groups in pool play.

Day 10 at the Tokyo Olympics was another important day for the U.S. teams in several team sports.

Sifan Hassan of the Netherlands started her bid to win three medals at the Tokyo Games by earning gold in the 5,000 meters.

Suddenly well behind the leaders, Dutch distance runner Sifan Hassan stood up and turned on the gas. Eleven of the world's fastest runners stood between her and victory.

World champion Sifan Hassan has made an incredible recovery from a fall at the final bell to win her 1,500-meter heat at the Olympics.

Julia Krajewski of Germany won individual eventing gold after countrymate and two-time defending champion Michael Jung stumbled during the cross country segment.

Track and field Day 4 events include finals in the women's 100m hurdles, women's discus, women's 5000m, men's long jump and men's steeplechase; and more.

'For me it is crucial to follow my heart,' she said in a statement. 'Doing that is far more important than gold medals.'

Sifan Hassan ran a patient, strategic race and trailed the leading pack most of the way before pushing hard on the last lap to win in a time of 14:47.89.

MONACO - The women's world record in the mile run, which has stood for 23 years, finally fell on Friday. The Netherlands' Sifan Hassan broke the record Friday night at the Monaco Diamond League with a time of 4:12.33. Russia's Svetlana Masterkova set the world record in 1996 with 4:12.56. "After you run a last 400 like that, and set a world record, it gives me so much confidence over 5000m." The 26-year-old Dutch runner's previous best time was 4:14.71, set last year at the London Diamond League meet.
