Building Brooklyn is not only an event, but a local business program designed for area businesses to boost brand visibility and engagement through the NYCRUNS Brooklyn Half Marathon and NYCRUNS ecosystem.
The NYCRUNS Brooklyn Half Marathon is our flagship race and one of the largest road races in the country. Local business partners will have the opportunity to reach as many as 25,000 athletes this year as well as many more spectators as the race proceeds from North Brooklyn to Prospect Park.
For partnership opportunities at either race, please email partnerships@nycruns.com.
Prospect Park Alliance is the non-profit organization that sustains “Brooklyn’s Backyard,” working in partnership with the City of New York. The Alliance was founded in 1987 to help restore Prospect Park after a long period of deterioration and decline. Today, the Alliance provides critical staff and resources that keep the park green and vibrant for the diverse communities that call Brooklyn home.
All participants sign up on this page; however, if you are part of an organization putting together a team of five or more participants, please email buildingbrooklyn@nycruns.com for more information.
