B.A.A. Half Marathon

Now in its 24th year, the B.A.A. Half Marathon has grown into one of the country's premier half marathons, drawing nearly 6,500 finishers in 2025 from across the globe. Nearly a third of runners return year after year, lured by a point-to-point course that winds through the streets of Boston, past landmarks and neighborhoods that pulse with history. The field is competitive at the front—winning times often hover around 61 minutes—but the wide, flat roads make this a PR-friendly race for all levels.

Race day typically greets runners with crisp, cool weather—averaging 41 to 58°F—and a spirited atmosphere bolstered by thick spectator support along the route. The B.A.A. brings its signature professionalism to every detail, from seamless logistics to ample aid stations. As the presenting partner, Dana-Farber Cancer Institute and the Jimmy Fund add a layer of purpose to the occasion.

The finish line celebration is a Boston affair, with runners gathering to share their efforts before heading back into the city. For anyone seeking a fast, well-organized half marathon with a charitable heart, this one delivers.
