Brooklyn running is built on variety in a way that actually shows up race morning. The same borough that sends you over bridge approaches and through DUMBO's cobblestones also trails off into the wooded Prospect Park loop and the long flat boards of the Coney Island boardwalk. Races here tend to feel like a cross-section of that personality, rooted in real neighborhoods with real texture.
The run clubs here are woven into the fabric of specific places - Greenpoint Runners along the waterfront, Black Roses NYC in the broader scene, BK Run Project among others. If you are training for a half and want company doing it, there is a crew that already runs your neighborhood.
By the numbers
The Brooklyn races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
Train for it
The fastest way to a start line is a standing group run. These Brooklyn clubs welcome Half Marathon runners of all paces.

We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 25, 2026.
The Holiday Half Marathon is the one race here with published finish-time results - it recorded a median finish of 1:55:45 across a field of 38 runners. That is a genuinely small, intimate race, not a massive event where you disappear into the crowd. The other five races have not published results, so there is no comparable figure for them.
Fall is the busiest stretch, with 4 of the 6 races running between September and November, and October alone has 3 of them. If your training block peaks in autumn, you have the most options. There are also 2 winter races for runners who prefer a quieter calendar.
There are 8 run clubs based in Brooklyn:
Several of them cluster around the Prospect Park loop and the Brooklyn Waterfront Greenway, which are the borough's main training grounds.
