The RBC Brooklyn Half is a half marathon held in Brooklyn, NY on May 15, 2027 (projected — not yet officially announced). With a Green Score of 7.8/10, it's a moderate race. The course is flat (~20 ft of gain per mile). Typical race-day weather is a mild 60°F, dew point ~50°F (10-year normal). Entry is around $135. Marathon Compass rates every race across terrain, climate, logistics, travel, and field size so you can find the one that fits you — and build a training plan tuned to your fitness.
Typical start-line conditions (30-year normal (NOAA 1991–2020)): 60°F with a dew point of 50°F. On the temperature-plus-dew-point scale used by our pace engine, that's 110 — a 0.5% pace penalty. Heat is a minor factor here in a typical year — a small early-pace cushion is enough.
