About the race
The Boston Half presented by Dana‑Farber Cancer Institute and the Jimmy Fund is a half marathon held on November 8, 2026 that begins and ends in Franklin Park and runs along the Emerald Necklace park system. The course passes the Arnold Arboretum, Jamaica Pond, Willow Pond, Olmsted Park and sections of the Riverway, Jamaicaway, and Arborway.
The field is limited in size; general registration opened July 8, 2026 and has reached capacity. The event lists 9,000 participants for race day. Entrants must be at least 14 years old on race day. Entry fee is $110 and entries are non‑transferrable, non‑deferrable, and non‑refundable.
Event services include gear check at the start area using the supplied plastic bag and the gear check tag on the bib, a Shirt Distribution Tent for participant shirts supplied by adidas, and a unicorn finisher medal for all finishers. Hydration on course will include Poland Spring water, Lemon Lime Gatorade Endurance Formula, and Maurten. Medical personnel will be on site. Electronic timing uses a scoring tag affixed to the back of the bib to generate net times; results are posted online and in the B.A.A. Racing App.
No parking is available in Franklin Park. Shuttle transportation is provided to the start area. Free youth races for participants up to 14 years old are offered alongside the event. Visit the organization's website for the most recent information.
