⏵ Course guide · Rollers, then a fast run to the beach
The RBC Brooklyn Half opens with rolling terrain through Prospect Park, then settles into a long, flat run down Ocean Parkway to the Coney Island boardwalk. I will walk you through how the lottery works and the course first, then give you a pacing plan for the rollers-to-flat split, plus free tools to dial in your own numbers.
These facts come from events.nyrr.org/rbc-brooklyn-half and public race reporting. The exact 2027 date was not published in one confirmable place; confirm the current date and lottery window on nyrr.org.
This course has a clean, honest structure: harder terrain early, faster terrain late.
The first few miles wind through Prospect Park, the course's only real elevation change. It is not a big climb by marathon standards, but it is enough to matter if you go out too hard, especially since it is the first thing you face fresh off the start line.
Once you clear the park, the course settles into a long, genuinely flat run down Ocean Parkway all the way to the Coney Island boardwalk finish. This is where the course earns its reputation as a fast PR option, a straight, exposed stretch that rewards even, disciplined pacing.
One of the largest half marathons in the US, running since 1981, sells out through a drawing, not open registration.
Most runners enter through NYRR's lottery. NYRR 9+1 members (nine qualifying races plus a volunteer credit the prior year) and charity runners have guaranteed paths that skip the drawing entirely. If you want a guaranteed spot, plan your NYRR race calendar or charity fundraising a year out; if you are applying cold, get your lottery entry in as soon as the window opens.
The course structure makes the pacing decision simple, if you respect it.
Run the early rollers by effort, not by your flat goal pace. Going out too hard through the park is the most common way to blow up a Brooklyn Half, since the long, exposed Ocean Parkway stretch that follows offers little forgiveness if your legs are already cooked.
Once the course settles onto Ocean Parkway, this becomes one of the more honest, controllable half marathon stretches you will run: flat, straight, and predictable. Use the race-time calculator to plan a mile-by-mile pace that leans slightly conservative through the park, then holds firm to the finish.

Through the NYRR lottery, the same drawing system used for the NYC Half. Guaranteed entry paths exist for NYRR 9+1 members (nine qualifying NYRR races plus one volunteer credit in the prior year) and charity runners fundraising for a partner organization. Without one of those paths, plan on the lottery deciding your spot, and apply as soon as the window opens since this race sells out fast every year.
Yes, once you clear the first few miles. The race opens with rolling terrain through Prospect Park, then settles into a long, genuinely flat straightaway down Ocean Parkway all the way to the Coney Island boardwalk finish. If you can hold your effort through the early rollers without overcooking your legs, the back half is about as fast and honest as a half marathon course gets.
The exact 2027 calendar date was not published in one confirmable place at the time of writing, though NYRR's site referenced the 2027 race cycle and application windows. Based on the race's consistent mid-May Saturday pattern, and the 2026 race running May 16, expect a similar mid-May Saturday date; confirm the exact 2027 date on nyrr.org.
Get through the Prospect Park rollers by effort, not by chasing your flat goal pace, since overcooking those early climbs will cost you on the long Ocean Parkway straightaway that follows. Once you hit the flat, straight run to Coney Island, that is where you can safely commit to your goal pace, using the race-time calculator to plan the split between the rolling start and the flat back half.
Mid-May in Brooklyn typically brings mild to warm conditions, highs around 65 to 70°F with possible humidity, but it can run hotter in some years. Since the back half of the course is exposed on Ocean Parkway with little shade, check the forecast in race week and be ready to adjust your pace target if the day trends warm.
