The 2026 Boston Marathon produced one of the strongest performances ever by American women, with four finishing in the top 10 and Jess McClain breaking the American course record. Multiple others placed within the top 20, showing depth across the field. This is one of the highest concentrations of top finishes by U.S. women in Boston Marathon history.

Sharon Lokedi (Kenya) won the race in 2:18:51, securing her second consecutive Boston Marathon title. She stayed in the lead pack through 20 miles, then made a decisive move after Heartbreak Hill. By mile 23, she had created a clear gap and ran unchallenged to the finish on Boylston Street.

Jess McClain delivered the top American performance, improving on her 2025 result and finishing fifth in 2:20:49. That time set a new American course record for Boston, breaking the previous mark set by Shalane Flanagan. 

Annie Frisbie finished eighth in 2:22:00. She remained consistent throughout the race, holding even splits from halfway through mile 25. This performance matches her top-10 finish from last year and improves her time by over a minute.

Emily Sisson placed ninth in 2:22:39. She ran conservatively through the first half and moved up steadily in the final 10 miles. This result marks a return to form for Sisson after injury setbacks in previous seasons.

Carrie Ellwood finished tenth in 2:22:53, crossing the line as the fourth American woman. She recorded one of the largest improvements in the field, lowering her personal best by nearly nine minutes from her previous personal best of 2:31:51 from Chicago in 2021. 

This year's Boston Marathon underscores a measurable shift in American distance running. With multiple women now capable of running in the low 2:20s and continuing to improve, the collective progress in American distance running is becoming hard to ignore. Based on the trajectory seen in Boston, a return to the top three is not just possible but is becoming increasingly likely in the near future.
