Eliud Kipchoge, the 39-year-old two-time Olympic champion and the only man ever to break two hours in the marathon, and Sifan Hassan, the 30-year-old star from the Netherlands, will take part in the 17th running of the Tokyo Marathon on March 3, with both aiming to set records and tackle the 26.2 mile distance. 

FloTrack will stream the Tokyo Marathon live. 

It will be a return for Kipchoge, who set the Tokyo record of 2 hours, 2 minutes and 40 seconds back in 2022, while Hassan will be fresh off wins in London -- where she shocked onlookers when she won in 2:18:33 -- and Chicago, where she clocked the second-fastest performance at the distance ever in 2:13:44. 

Hassan won Olympic titles in the 5,000m and 10,000m in 2021, posting times of 14:36.79 and 29:55.32 before jumping into the marathon in April -- less than two years later -- and debuting at 2:18:33, a time that came against one of the best women's fields ever assembled. 

"I am so excited to announce my participation in my next marathon," Hassan said in a release. "I feel Tokyo is the perfect preparation towards the Paris Olympic Games, because I have great Olympic memories in the city of Tokyo and I feel I can fuel my Olympic fire there."

Kipchoge, meanwhile, is largely considered the GOAT of distance running after becoming the only man to ever break two hours in the marathon in 2019. The NN Running team member currently owns the second-fastest marathon time on record with his 2:01:09 from 2022 in Berlin. 

Kipchoge, who's run 21 marathons over his career, also has won the last two Olympic marathons in 2016 and 2021. He has 18 total wins on his record and in 2019 ran 1:59:40 during the sub-2 project that was set up in Vienna. 

"I have good memories in Japan," Kipchoge said in a release. "I won my Olympic gold medal there and ran the course record in the Tokyo marathon. Last time, I was grateful for the organization to organize the event during such a difficult time during the Covid-19 pandemic. My aim was to set the course record and it was great to achieve that." 

No athlete in Olympic history has won three straight marathons across 12 years of competition. 

The Olympic marathon will take place in August in Paris.
