Brooklyn Half Marathon Guide

The Brooklyn Half Marathon is one of the flatter, faster courses in New York Road Runners' 5-borough race series, running from Prospect Park to the Coney Island boardwalk. It's a popular pick for both New Yorkers chasing a personal record and out-of-town runners looking for a big-city race weekend.

The Course

The race starts near the Brooklyn Museum and heads into Prospect Park for a loop of roughly seven miles. Designed by Frederick Law Olmsted — the same landscape architect behind Manhattan's Central Park — Prospect Park is one of the most scenic stretches of the course, with meadows, forest, and lakes, but it also holds the route's main challenge: a long, gradual hill that isn't steep but that most runners feel by the time they're through it.

After Prospect Park, the course straightens out onto Ocean Parkway for a long run toward Coney Island. From around mile six onward it's flat to gently downhill, which is a big part of why the Brooklyn Half has a reputation as a personal-record course. The final mile follows the Coney Island boardwalk to the finish.

In 2022, the course was rerouted to start in North Brooklyn and wind along the waterfront, passing under the Williamsburg, Manhattan, and Brooklyn Bridges before eventually connecting to the Prospect Park and Ocean Parkway stretch. Confirm the current-year route map on NYRR's site, since course details can shift between editions.

Race Day Logistics

The race typically uses a two-wave start to manage the field size, with lower bib numbers starting first and higher bib numbers following roughly 30-35 minutes later — runners are usually asked to be in their corrals at least half an hour before their wave starts. Aid stations, medical support, and restrooms are typically placed at roughly every mile along the course.

Races with a large field usually set a course time limit, often in the neighborhood of three hours, with a sweep bus available from around the midpoint for runners who fall behind the required pace; you can typically keep going on the sidewalk past that point, but full course support may not be available. Confirm the current year's cutoff and sweep policy on NYRR's site, since these details can change.

Weather

Late May in Brooklyn typically brings temperatures in the 50s to upper 60s°F at race time, with occasional rain — but any given race morning can run warmer than average. If conditions turn warm, plan to slow roughly 10-20 seconds per mile for every 5°F above 60°F rather than trying to hold a cooler-weather goal pace; going out too aggressively on a warm morning is one of the most common ways runners fade in the second half.

Registration and Entry

Entry to the Brooklyn Half Marathon typically runs through one of a few paths: a lottery, a time qualifier for runners who meet a qualifying standard, or one of NYRR's guaranteed-entry programs for members who've met certain participation requirements. Which paths are open and when registration windows fall changes from year to year, so treat NYRR's official race page as the source of truth rather than any third-party calendar or older guide, including this one.

Pre-Race Expo and Post-Race Party

The pre-race expo has typically been hosted in Brooklyn's Dumbo neighborhood, where runners pick up their bib and race shirt alongside vendor booths, live music, and food. After the race, NYRR has typically hosted a beach party at the Coney Island finish area with awards, food, and activities — a fitting way to spend the rest of race day if you're not rushing to travel home.
