Eliud Kipchoge of Kenya has won gold in the men's marathon, finishing with a time of 2:08:38 for his fourth career Olympic medal.
Kipchoge is one of the world's most successful distance runners. He holds the world record for the marathon and won the race at the 2016 Rio Olympics.
“I think I have fulfilled the legacy by winning the marathon for the second time, back-to-back," Kipchoge said after the race. "I hope now to help inspire the next generation."
The Netherland's Abdi Nageeye took silver with a time of 2:09:58, and Belgian Bashir Abdi won bronze with a time 2:10:00.
Kipchoge's win gives Kenya its fourth gold medal of the 2020 Tokyo Olympics and its 10th medal overall.
