Boston Marathon F18-39: Obiri Storms Through the Newton Hills to Claim Copley Square

• Hellen Obiri wins in 2:21:38 (5:24/mi), surging from 5th to 1st in the women's field across the Newton Hills to take the tape.
• The top five finished within 32 seconds — Amane Beriso 2nd in 2:21:50, Lonah Salpeter 3rd in 2:21:57, Ababel Yeshaneh 4th in 2:22:00, and Emma Bates 5th in 2:22:10 — one of the tightest elite women's finishes the race has seen in recent editions.
• Amane Beriso led or co-led through five of six checkpoints, running the fastest women's split on the 30K–20M stretch, only to be overhauled in the final miles.
• Desiree Linden, the 2018 Boston champion, crossed 17th in the F18-39 group at 2:27:18 (5:37/mi), running a full 12:04 slower than the 2018 winning time she set on this very course.

Under a grey, drizzly Patriots' Day sky — 49°F, 90% humidity, and a 10 mph headwind that made every 5:25/mi feel harder than it looked on paper — the women's race at the 128th Boston Marathon delivered a tactical masterpiece with a decisive late move. Hellen Obiri was nowhere near the front early, sitting 5th at the 5K checkpoint, but she was already hunting. By the time the field hit the Newton Hills, she had climbed to 1st, and her fastest women's split between 10K and 15K signaled that she was running her own race on her own terms.

The story of the middle miles, though, belonged to Amane Beriso. The Ethiopian led or shared the lead through five of the six tracked checkpoints and posted the fastest women's split on the 30K-to-20-mile stretch — a punishing section where most runners are already negotiating with their legs. But Obiri, who had briefly slipped back to 3rd after her early surge, found another gear in the final miles and came back through to win in 2:21:38. Beriso held on for 2nd in 2:21:50 — just 12 seconds separating the two after 26.2 miles.

Lonah Salpeter was the opening act, posting the fastest women's split of anyone from 5K to 10K on her way to 3rd place in 2:21:57. Ababel Yeshaneh, who ran the second-fastest women's split over that same early stretch, finished 4th in 2:22:00, and American Emma Bates — who owned the fastest women's split from 15K to 20K — rounded out the top five in 2:22:10. Those five women were separated by just 32 seconds across more than two hours of racing from Hopkinton to Copley Square.

Further back, the F18-39 field of 4,884 finishers told its own stories. Nazret Weldu took 6th in 2:23:25, a full 1:15 behind Bates, marking the point where the lead pack truly separated from the rest. Aliphine Tuliamuk (11th, 2:24:37) and Nell Rojas (14th, 2:24:51) were standout American performances in a deep field. And Desiree Linden, the 2018 Boston champion, completed her return to the course at 2:27:18 — a reminder of just how extraordinary that 2018 win in brutal conditions truly was.
