Untouchable, Jepchirchir won her fifth victory in as many races contested since 2019. Along the way, she had triumphed in Tokyo in August 2021, before winning in New York three months later.
Here she is, adding a second major marathon (the other four are Berlin, Tokyo, London and Chicago) to her list.
But it took a handful of seconds (four) for her to beat the tough Ethiopian Ababel Yeshanei in 2 h 21 min 01 sec.
They broke away at breakneck speed halfway through the race with the Kenyan Joyciline Jepkosgei.
But the latter, winner in New York in 2019 and in London last year, ended up cracking, and the duel for victory was superb.
Less than two km from the finish Jepchirchir placed a first attack but Yeshanei managed to pick up.
She had to wait for her fourth acceleration 100 meters from goal to have the last word.
Her compatriot Mary Wacera Ngugi (2 h 21 min 32 sec) completed the podium.

"When I got to the 41st kilometer I knew I was going to win the race. I was just saving energy for the finish. Ababel was so strong...I just believed in myself and when you see the ribbon at the finish, that's where the strength comes", reacted the one who succeeds her compatriot Diana Kipyogei on the list of winners.
Kenyan men's podium
Among the men, Evans Chebet was less expected than his compatriots Benson Kipruto and Lawrence Cherono, the two previous winners, who were favorites in the absence of double Olympic champion and world record holder Eliud Kipchoge, and Ethiopian Kenenisa Bekele .
But it was he who won his first victory in a major marathon alone at the age of 33 in 2 h 06 min 51 sec, thanks to a sharp attack at the 33rd kilometer.

"I'm very proud of myself, I knew I had the legs to win," commented Chebet, 4th in London last year and winner in Valencia in 2020.
Cherono finished second (2:07:21) and Benson Kipruto (2:07:27) completed Boston's first all-Kenya podium since 2012.
The Boston Marathon, one of the most prestigious of the season, returned to its traditional Easter Monday window for its 126th edition, after being canceled in 2020 at the start of the pandemic and moved to October 2021, again due to the Covid -19.
Some 30,000 participants, all vaccinated, according to the imposed protocol, beat the pavement, 10,000 more than last year.
