Boston Marathon 2025 route
The 2025 Boston Marathon will start in Hopkinton. Runners will then reach Ashland at roughly the four-mile mark and proceed to Framingham six miles in.
From there, runners will pass through Natick and Wellesley, which sits just before the halfway point. Newton and Brookline mark the final stretch before the race ends on Boylston Street in Boston.
The entire course length is 26 miles and 385 yards — or 26.2 miles — which is standard marathon length. The finish line is located in Copley Square, a public square in Boston known for its historical landmarks.

Boston Marathon winners
Both 2024 champions on the men’s and women’s side will compete again in 2025. Sisay Lemma, an Ethiopian runner, will look to win it all again on the men’s side after finishing the event in 2:06:17 last year.

On the women’s side, Kenyan runner Hellen Obiri is going for a historic victory. Obiri has won the last two Boston Marathons. If she takes home the win in 2025, it would mark the fifth time a woman has won the event in three consecutive years. Fatuma Roba is the last woman to accomplish that feat, winning the Boston Marathon from 1997-99.
The Boston Athletic Association maintains a full list of winners at the event, dating back to 1897, the first year the Boston Marathon was held.
