Sunday, November 9 2025 – Boston, Massachusetts – The 2025 edition of the Boston Half (presented by Dana‑Farber Cancer Institute and the The Jimmy Fund) promises a thrilling blend of elite competition and autumnal parkway charm as roughly 9,000 participants from 44 U.S. states and 98 countries converge at Franklin Park for this iconic event.

Setting the Scene

At an 8:00 a.m. Eastern Time start, the field will launch from historic Franklin Park—an integral part of Boston’s storied park-system—on an out-and-back course winding through the city’s famed Emerald Necklace. This tranquil landscape of parkways and gentle elevation changes offers a refreshing contrast to typical city-street half-marathon tours.

The Course

The 13.1-mile route begins and ends in Franklin Park, carrying runners over picturesque parkways framed by autumn foliage, with rolling terrain that tests both endurance and rhythm. The course offers a departure from crowded downtown urban routes and instead immerses runners in one of Boston’s most scenic green corridors.
