The annual Dana-Farber Cancer Institute Jimmy Fund Half Marathon is Sunday from 8 a.m. to 10 a.m. It begins and ends at White Stadium in Franklin Park.
The road closures and detours for the course route and abutting roads in Forest Hills are shown on the map. In addition, segments of Pond Avenue, Perkins Street and Francis Parkman Drive will also be affected.
It's a good idea not to drive in the area at all until the event is over.
Here's a link to the Boston Athletic Association's website, which has much more information on the even and its traffic impacts.
