Sharon Lokedi confirmed her status as the defining women's marathoner of the decade at Boston by running 2:18:51 to retain her title on Monday, becoming the first woman since Catherine Ndereba in 2005 to successfully defend on the Hopkinton-to-Boylston course. The Kenyan's time was 89 seconds outside her own 2:17:22 course record from 2025 but proved more than enough to hold off compatriot Loice Chemnung, who finished second in 2:19:35, and Mary Ngugi-Cooper, third in 2:20:07. Lokedi's victory completed a Kenyan double with John Korir's course-record men's win and sealed the most dominant Kenyan day in Boston since 2011.
The women's race was ferocious from the gun. A lead pack of twelve covered the first 5km in 14:48.5 — widely reported as the fastest opening 5K in the women's race at Boston and pace that extrapolated to a 2:05 marathon — before the undulations and a stiff early headwind re-ordered the field. Lokedi looked under pressure at 10 miles, briefly dropped to the back of a group of six as Chemnung pressed, and was visibly working on the long climb out of Newton Lower Falls. But the defending champion has built her career on Boston's hills, and by the top of Heartbreak Hill at Mile 21 she had surged clear to open a margin that would not be closed.
Chemnung, making her Boston debut after a breakthrough 2:17:11 at Seville in February, pressed hard through the final four miles but could not bridge the gap, finishing 44 seconds back. Ngugi-Cooper, the former Kenyan 10,000m internationalist who now represents her adopted Britain in road races, secured a first Abbott World Marathon Majors podium at the age of 37 with a gutsy 2:20:07 for third. Ethiopia's Amane Beriso, the 2024 World champion, faded from the lead pack late to finish fourth in 2:20:32, while American Jess McClain took fifth in 2:20:49 — a performance that rewrote the U.S. record books in its own right (separate story).
Lokedi afterwards credited a winter training block in Colorado for the late-race strength that separated the top three, admitting she had deliberately held back in a first half that might, with clearer air, have produced an assault on her own course mark. 'The plan was always to race the women, not the clock,' she said at the finish line. 'The weather and the pace made it very hard early. I just kept telling myself: trust Newton, trust the hills. They are my friends.' The 31-year-old collected the standard $150,000 winner's purse and becomes the fourth woman to win Boston in consecutive years since the race turned fully professional.
The result further complicates a women's marathon landscape already heading into Sunday's London race loaded with talent. With Sifan Hassan and Peres Jepchirchir both having withdrawn from London through injury, Tigst Assefa's title defence will now carry the additional weight of whoever carries the mantle of the sport's dominant marathoner — and Lokedi's second Boston crown inside twelve months has made that argument considerably harder to win in Assefa's favour. Attention will next turn to the autumn when Lokedi is expected to line up at either Chicago or New York as she pursues what would be a third major in four starts.
