World record holder Eliud Kipchoge vowed to enjoy the moment before setting his next goal after successfully defending his Olympic men's marathon title at Tokyo 2020 on Sunday.

The 36-year-old Kenyan won by over a minute in a time of two hours, eight minutes and 38 seconds, with Dutchman Abdi Nageeye and Belgium's Bashir Abdi taking silver and bronze respectively.

The triumph was a coronation for Kipchoge who won gold at Rio 2016, while he claimed bronze and silver Olympic medals in the 5,000m in Athens and Beijing respectively.

Kipchoge, who is widely regarded as the greatest marathon runner in the modern era, refused to look ahead after his latest win.

"I am a believer of the philosophy that you should only chase one rabbit," Kipchoge said. "If you chase two, then you cannot get all of them.

"For the last two years I have been focusing on the Tokyo Olympic Games 2020, so I will only plan the next thing when there is a big job ahead of me.

"What was in my bucket list was Tokyo 2020. So I will go back now, talk to my coach, and see what the opportunities are and then I will come back to you people. But, for now, I want to enjoy winning here in Tokyo."

Nageeye and Abdi claimed second and third with an enthralling final sprint, edging out Kenyan Lawrence Cherono for the medals. The Dutchman willed on training partner Abdi in the dying stages.

"I was just telling him to stay with us, stay with us the last one (kilometre)," Nageeye said. "I felt good as that is what I was doing. I wasn't volunteering, but I knew if he stayed until the end, the last 200 metres, close your eyes and just sprint."

KENNY CLAIMS HISTORIC SEVENTH OLYMPIC GOLD

British cyclist Jason Kenny secured his seventh career Olympic gold medal, winning the men's keirin final on the final day of the Games after a remarkable race where he stormed ahead unopposed.

Kenny claimed his historic gold by 0.763 seconds from Malaysia's Mohd Azizulhasni Awang who edged Harrie Lavreysen of the Netherlands on the line to claim silver and bronze respectively.

In a bizarre race, the 33-year-old Kenny pulled clear with two laps to go, with second-placed Matthew Glaetzer not following him, powering ahead and eventually crossing the line on his own.

"It was such a long way," Kenny said. "I felt like the last lap took me about half an hour. But I got there in the end. I still can’t believe I crossed the line on my own."

He first won gold in the team sprint at Beijing 2008, following with two triumphs at London 2012 and three at Rio 2016, including the keirin title which he successfully defended.

Kenny's gold medal means he is the most successful British athlete in Olympic history, pulling clear of cyclist Chris Hoy.

Jason's wife Laura Kenny was involved in a huge crash in the opening round of the women's omnium and missed out on the medals, with gold won by USA's Jennifer Valente. Japan's Yumi Kajihara won the host country's first medal in cycling at Tokyo 2020 with silver.

Canada's Kelsey Mitchell won the gold medal from Ukraine's Olena Starikova in the women's sprint, with Hong Kong's Lee Wai Sze taking bronze.

USA CONTINUE WOMEN'S BASKETBALL DYNASTY

The United States women's basketball team claimed their seventh consecutive gold medal with a 90-75 victory over hosts Japan.

Brittney Griner top-scored with 30 points for USA, along with five rebounds and two assists.

Team USA opened up a nine-point lead at the first change and they were never headed, with a strong display headed by Griner.

USA only hit four three-pointers for the game compared to Japan's eight, but the favourites played to their strengths with strong offensive and defensive contributions from A'ja Wilson and Breanna Stewart.

Wilson added 19 points, seven rebounds, five blocks and five assists, while Stewart was exceptional with 14 points, 14 rebounds, three blocks and five assists.

USA veteran Sue Bird signed off on her Olympic career with a fifth gold medal.

USA MOVE CLEAR WITH VOLLEYBALL TRIUMPH

The United States moved into the outright lead on the gold medal table after clinching their first-ever women's volleyball victory.

USA triumphed 3-0 over Brazil, winning 25-21 25-20 25-14 in a dominant final display.

The gold medal took USA's tally to 39 golds, moving ahead of China with 38 as the final day continued to unfold.
