Women's Boston Marathon: Obiri edges a breathless four-way sprint to the tape

• Hellen Obiri wins in 2:21:38, averaging 5:24/mi — the fastest women's time at Boston since the 2022 course record of 2:21:01.
• Three seconds covered the top three: Amane Beriso (2nd, 2:21:50) and Lonah Salpeter (3rd, 2:21:57) were never more than a handful of strides behind.
• Emma Bates (5th, 2:22:10) posted the fastest women's split from 15K to 20K and was the top American finisher in a field of 11,423 women.
• The lead changed hands repeatedly: Beriso held the top spot through four of six tracked checkpoints, only to be overtaken in the final stretch.

On a cool, drizzly Patriots' Day in Boston — 49°F, light rain, and a 10 mph wind along the point-to-point route from Hopkinton to Copley Square — the women's race delivered one of the most tightly contested finishes the World Marathon Major has seen. Hellen Obiri crossed in 2:21:38, but the story of how she got there was anything but straightforward.

Amane Beriso ran like a woman in command for most of the afternoon. She led at the 5K mark and held the top spot through the 20-mile checkpoint, also posting the fastest women's split from 30K to 20 miles — a sign she was pushing hard through the race's most punishing stretch, including the Newton Hills and Heartbreak Hill. Meanwhile Obiri was threading her way through the field: she entered the tracked checkpoints as low as 5th among women, surged to 3rd, briefly slipped to 3rd again after the halfway point, then clawed back to 2nd before making her decisive move to the front. Her fastest women's split from 10K to 15K was the engine of that surge.

Lonah Salpeter (3rd, 2:21:57) and Ababel Yeshaneh (4th, 2:22:00) were in the thick of it throughout. Salpeter had posted the fastest women's split from 5K to 10K — with Yeshaneh right behind her recording the second-fastest on that same segment — and both moved steadily through the field to hold their positions all the way to Copley Square. Thirteen seconds separated Obiri from Yeshaneh at the finish; seven of those seconds came between 2nd and 4th alone. Emma Bates (5th, 2:22:10) rounded out the lead pack with a strong 15K-to-20K split, finishing as the top American in the field.

Behind the lead group, Nazret Weldu (6th, 2:23:25) was the first to break from the pack, finishing 1:15 back. A cluster of nine women — Angela Tanui through Viola Cheptoo — all came home between 2:24:12 and 2:24:49, separated by just 37 seconds across places 7 through 13. Desiree Linden, the 2018 Boston champion, finished 18th in 2:27:18, and Annie Frisbie (20th, 2:28:45) closed out the top 20 among 11,423 finishers on the day.
