Peres Jepchirchir and Brigid Kosgei set the pace for most of Saturday's women's marathon, and the only question entering the final five kilometres was which Kenyan would cross the line first. 

Jepchirchir finally broke from her countrywoman with a little over two kilometres to go and pulled away to win by 16 seconds.

Kosgei's second-place finish made Kenya the first nation to claim gold and silver in the event at the same Olympic Games.

“I pushed on the pace [and when I opened the gap] it was like, 'Wow, I’m going to make it. I’m going to win,'" Jepchirchir said. 

"It feels good. I’m so, so happy because we win as Kenya. First and second. I thank my god so much. I'm happy for my family. I'm happy for my country, Kenya."

Ten seconds behind Kosgei, Molly Seidel of the USA shouted "Yes! Yes!" as she crossed the line for a stunning bronze medal in only her third competitive marathon.

Seidel is the third US woman to medal in the marathon, following Joan Benoit Samuelson's gold at the inaugural women's race in Los Angeles in 1984 and Deena Kastor's bronze at Athens 2004.

She said she took inspiration from her friend Courtney Frerichs' aggressive approach that led to a silver medal in the 3,000m steeplechase this week.

"Seeing her do that and race aggressively was truthfully what gave me the strength to not be afraid to stick my nose in it," Seidel said.

"It is just to go out, stick your nose where it doesn’t belong and try and make some people angry. My goal today was just to go in and for people to think, 'Who the hell is this girl?'."

ANOTHER GOLD FOR MCGEE FAMILY

JaVale McGee was a late addition to the USA basketball squad, but Saturday's victory over France made him a part of history.

McGee's mother Pam won gold with the USA in basketball at the 1984 Los Angeles Games, and she and JaVale are now the first American mother-son combo to win gold in any sport.

“It's an amazing feeling man," McGee said. "I got a gold medal, my mother's got a gold medal. You can't really explain it, just knowing you're the best in the world.

“If that don't add to the resume, I don't know what will. It's a family resume. That's what it’s all about, in the end, is family.”

YAFAI WINS BOXING GOLD FOR BRITAIN

Galal Yafai became the first British man to win boxing gold since London 2012, defeating Carlo Paalam of the Philippines for the flyweight title Saturday.

Yafai knocked down Paalam in the opening round and never looked back, winning 4-1.

The 28-year-old Birmingham native competed in Rio as a light flyweight but lost in the second round.

He is the first Brit to medal in the men's fly since 1956.

Paalam is the first man from the Philippines to medal in any sport since boxer Mansueto Velasco took silver in the light fly at Atlanta 1996.

BEACH VOLLEYBALL NEWCOMERS TAKE MEDALS

A sport traditionally dominated by Brazil and the USA saw three newcomers on the podium on Saturday.

The Norway duo of Anders Mol and Christian Sorum defeated Viacheslav Krasilnikov and Oleg Stoyanovskiy, representing the Russian Olympic Committee, to take home the gold medal.

In the bronze-medal match, Ahmed Tijan and Cherif Younousse of Qatar downed Edgar Tocs and 2012 bronze medallist Martins Plavins of Latvia.

None of the podium nations had won a medal of any kind in men's or women's beach volleyball before, though the winners do have an Olympic legacy of sorts.

Mol's mother, Merita Berntsen, placed ninth with partner Ragni Hestad in the first beach volleyball competition at the 1996 Atlanta Games, then retired when Anders was born the next year.

"My mum thought it was going to be really hard to travel around with two kids, because my brother was born in 1994. She had me and then quit," Mol said. "I always dreamed of beating my mum in the Olympics. She got a ninth [place[. I was actually really happy when we made it to the quarter-finals because we became historical by achieving [at least] a fifth place.

"It has been a journey for a long time and our parents and families are very proud of us right now."

SIXTH KAYAK GOLD FOR HUNGARY'S KOZAK

Danuta Kozak claimed her sixth Olympic gold medal as Hungary won the women's sprint kayak four 500 metres.

The 34-year-old teamed with Tamara Csipes, Anna Karasz and Dora Bodonyi to hold off Belarus and Poland.

It was Kozak's third consecutive gold in the fours after taking silver in the event in her Olympic debut in Beijing.

She also won gold in the K1 500m in London and Rio, and in the K2 in Rio. She took bronze in the K2 earlier this week, so Saturday's win gives her eight Olympic medals overall.

In other sprint kayak finals, Germany won the men's kayak four 500m, China took the women's canoe double 500m and Isaquias Queiroz dos Santos of Brazil won the canoe single 1000m.

The United States cut China's lead at the top of the medal table to five as they collected four golds on day 13 of the Games.

Coming into Thursday's events, China boasted a seven-gold buffer as leaders but that was reduced by the USA's Katie Nageotte in the women's pole vault and Ryan Crouser in the men's shot put – the latter of which became a back-to-back Olympic champion.

More golds followed for the USA, with Nevin Harrison winning the women's single canoe 200m sprint – her country's first medal in either canoe or kayak sprint since 1992 – and David Taylor succeeding in the men's 86kg freestyle wrestling in the last second.

After shooting a blank the previous day, China ensured a five-gold gap going into Friday as the women's table tennis team continued their dominance, overcoming Japan to secure their fourth gold in four consecutive Games.

The table-toppers have now won all four of the women's diving events in Tokyo, too, as 14-year-old Quan Hongchan set a world record in the 10m platform, making it a China one-two with fellow teenager Chen Yuxi.

Defending Olympic champion Risako Kawai, who is also a three-time world champion, triumphed once more in the women's 57kg wrestling freestyle, meaning early leaders Japan remain in third with a gold count of 22.

Australia suffered shoot-out heartbreak in the men's hockey final but climbed up to fourth with men's kayak double 1000m sprint success and their first-ever Olympic gold medal in skateboarding, courtesy of Keegan Palmer's park win.

Their 17 gold medals at the Games with three days to go equalled Australia's best-ever haul, matching the total they collected at Athens in 2004. 

The Russian Olympic Committee leaped up a spot to fifth as Zaur Uguev was crowned champion in the men's 57kg wrestling freestyle and Albert Batyrgaziev fought to gold in the men's featherweight boxing.

Great Britain, who now boast 16 medals after winning just the one event on Thursday, slipped back down to sixth position with Matthew Walls' omnium gold ending Team GB's frustrating unsuccessful spell in the cycling track events.

Favourite Grant Holloway said nerves got the better of him after finishing second to Jamaica's Hansle Parchment in the men's 110 metres hurdles Olympic final.

The American led at the halfway mark but faded over the final 20 metres as he was beaten by his 31-year-old rival.

Parchment triumphed with a season-best time of 13.04 seconds, ahead of Holloway in 13.09, lucky to scrape ahead of Jamaican Ronald Levy who took bronze with 13.10.

Holloway and Parchment had run in the same heat and semi-final prior to the final, with the American winning both, before falling short in the all-important race.

"I think the anxiousness and the nerves got the better of me towards the end and I got sloppy with my form," Holloway said. "He got me this time but I'll make sure I get him in the next."

He added: "Hats off to Hansle for an amazing race. I was watching him when I was in high school. He's a hell of a competitor. He has an amazing race plan, he executed to the best of his ability."

Parchment admitted he learned from losing to Holloway in the previous two runs.

"I made some changes to my start, because I knew if I was going to catch up, I had to be closer in the first half," Parchment said. "I think I ran through pretty well. I maintained composure. It was a great race."

Portugal's Pedro Pichardo earned gold medal glory with a national record 17.98m in the men's triple jump.

Pichardo's triumphant effort came with his third attempt, while China's Zhu Yaming claimed silver with a personal best of 17.57m. Burkina Faso's Hugues Fabrice Zango took the bronze with 17.47m.

USA's defending champion Ryan Crouser threw an Olympic record 23.30m to win the men's shot put gold.

Crouser bettered the Olympic mark he set five years ago in Rio de Janeiro to win from countryman Joe Kovacs (22.65m), while New Zealand's Tomas Walsh (22.47m) claimed bronze.

EARLY SCARE AS USA REACH FINAL

The United States trailed by 15 points in the second quarter against Australia but rallied to qualify for the men's basketball gold medal match.

USA won 97-78 over Australia, who have never won an Olympic medal in men's basketball having finished fourth four times.

The Boomers had raced to a commanding position early on as Team USA struggled from beyond the arc.

Yet the reigning Olympic champions reduced the margin to three points by half-time and went up several gears with a 32-10 third quarter.

Brooklyn Nets star Kevin Durant top-scored again with 23 points and nine rebounds, while Devin Booker had 20 points.

USA will face either France or Slovenia in the final as they chase a fourth straight gold medal.

CARRINGTON MAKES NEW ZEALAND HISTORY

New Zealand's Lisa Carrington added a third Tokyo 2020 gold medal to her haul, landing the title in the women's kayak single 500m final.

Carrington claimed her fifth-ever Olympic gold with a strong victory in 1:51.216, from Hungary's Tamara Csipes and Denmark's Emma Jorgensen.

She becomes the first athlete from New Zealand to win five Olympic gold medals, surpassing the four of Ian Ferguson, also in canoe sprint between 1984 and 1988.

Carrington is the fourth woman at Tokyo 2020 to win three gold medals, after Australian swimmers Emma McKeon (four) and Kaylee McKeown (three) and South Korean archer An San (three).

GERMAN ADDS GOLD IN OPEN WATER

After winning bronze in the 1,500m in the pool, Germany's Florian Wellbrock won the men's marathon swimming in open water.

Wellbrock won in one hour, 48 minutes and 33.7 seconds across 10 kilometres, finishing 25.3 seconds ahead of Hungary's Kristof Rasovszky for silver, with Italy's Gregorio Paltrinieri earning bronze.

The size of the German's victory was the biggest margin in Olympic marathon swimming history.

“It’s a little bit unreal," Wellbrock said. "The first seven (kilometres) of this race felt really easy."

AUSSIE SKATEBOARDING WINNER

Keegan Palmer won Australia's first-ever skateboarding gold medal with two amazing runs in the men's park final.

The 18-year-old's first run scored 94.04 before a throwaway second round. Palmer backed it up on his final run with a staggering top score of 95.83.

Brazilian Pedro Barros was next best with 86.14 for silver, while Cory Juneau claimed bronze with 84.13.

The event was the final skateboarding medal opportunity from the sport in its debut Olympics.

Norway's Karsten Warholm smashed the world record in the men's Olympic 400 metres hurdles final, breaking the 46-second barrier on the way to gold medal glory.

Warholm finished in 45.94 seconds, well ahead of his own previous record mark of 46.70. USA's Rai Benjamin claimed silver in 46.17, also beating the old world record, with Alison dos Santos taking bronze in 46.72.

"It's by far the biggest moment of my life," Warholm said. "It defines everything, all the hours I put in, everything that my coach has been working for.

"With all the respect for all the athletes, there are athletes that were not good that will get an Olympic gold. Rai running 46.17 would deserve a gold medal. It is crazy, it is just an honour to be a part of it. I never thought in my wildest imagination that this would be possible."

Asked about his dash to the line in the closing metres, Warholm added: "I couldn't even feel my legs. I knew I had a crazy American trying to catch me, so I ran for my life."

Germany's Malaika Mihambo admitted she could not watch the finale to the women's long jump as she won gold.

Mihambo took the lead with a jump of 7.00m with her final attempt before USA's Brittney Reese and Nigeria's Ese Brume had their last jumps.

Neither could better the leading mark, with Reese settling for silver with 6.97 metres on countback ahead of Brume.

"It was really hard to watch, so I tried to just have a sneak peek on the display and see how far it was," Mihambo said.

"I really don't like this position where you cannot do anything about it, and you just have to let the girls do what they're able to do. You have to wait, so it was a horrible moment, but at least it was short.

“I feel overwhelmed. It was, I think, the most exciting women’s long jump competition in history."

DURANT DOMINATES AS USA SURVIVE SCARE

The United States did not have it all their way but triumphed 95-81 over Spain to seal a spot in the men's basketball semi-finals.

Spain led by as much as 10 points in the second quarter before USA drew level by half-time and accelerated in the second half. Spain again closed within four points of the gold medal favourites in the final quarter, inspired by Ricky Rubio's 38 points.

Kevin Durant excelled for Team USA, with 29 points and four assists, while Jrue Holiday contributed 12 points and five assists as they capitalised on a 17-9 turnover differential.

USA lost to Australia and Nigeria in exhibition games prior to Tokyo 2020 before losing their Olympics opener to France but have since steadied.

The winner of Australia-Argentina will play USA in the semi-finals on Thursday.

NBA duo Zoran Dragic (27 points, six rebounds and four assists) and Luka Doncic (20 points, eight rebounds and 11 assists) starred as Slovenia also progressed to the semi-finals with a 94-70 win over Germany.

CARRINGTON'S GOLD KAYAKING DOUBLE

New Zealand's Lisa Carrington had a golden day in the kayaking, remarkably winning two gold medals within an hour.

Carrington won her third straight gold in the women's kayak single 200m with an Olympic best time of 38.12 seconds, ahead of Spain's Teresa Portela and Denmark's Emma Jorgensen.

The New Zealander backed up alongside Caitlin Regal to win the women's kayak double 500m final with a world best time of 1:35.785.

Carrington joined fellow kayakers Ian Ferguson and Paul MacDonald and equestrian great Sir Mark Todd as the only New Zealanders to have won five medals at the Olympic Games.

The 32-year-old may win more medals too, competing in the K1 500 event which starts on Wednesday.

“Today was about taking just one race at a time," Carrington said. "There's a plan, and it was just about executing it. For me, it was just trying to stay in the moment and doing the best I can. We've worked really hard and knew today was going to be a big day.”

HENDRICKX POWERS BELGIUM INTO HOCKEY FINAL

World champions Belgium qualified for the gold medal match of the men's hockey after a commanding final quarter sealed a 5-2 win over India.

Belgium piled on three fourth-quarter goals to guarantee a medal in the decider where they will face either Australia or Germany.

Alexander Hendrickx scored a hat-trick including two of the Red Lions' goals in the final quarter after India had fought back from an early deficit to lead 2-1 at quarter-time.

Drag flick expert Hendrickx has scored an unrivalled 14 goals during Belgium's Tokyo 2020 campaign, eight clear of the next best, Australia's Blake Govers.

Hendrickx said: "It's really a team job that comes together. It's my name on the scoresheet, but it's a team job."

World number one Australia and sixth-ranked Germany meet later on Tuesday to determine the other gold medal match finalist.
