Race Day Weather
Cool start — fast day potential, warming through the race
A cool 49°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temperatures rising to 62°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing.

Over 20,000 runners will complete a remarkable running journey at the NYCRUNS Brooklyn Half Marathon, one of the nation's biggest, and Brooklyn's best, half marathon!
The iconic route starts in hip North Brooklyn and winds around the waterfront taking you under the historic Williamsburg, Manhattan, and Brooklyn Bridges while delivering eye popping views of Manhattan.
From there, the route heads up the historic concourses of Fulton Street & Flatbush Avenue before passing through Grand Army Plaza and into fabled brownstone Brooklyn before finishing in Prospect Park. Source
