The New York City half marathon returns for 2025 today, featuring a new route from Brooklyn to Manhattan. An estimated 28,000+ runners are participating in the United Airlines NYC Half, as the course travels across the Brooklyn Bridge for the very first time.

On Sunday, the runners will go over the Brooklyn Bridge for the first time because of construction in Lower Manhattan.

The events will be accompanied by a number of street closures. Read on for the streets to avoid on Sunday and Monday.

A new beta app will let you track runners during the 2025 United Airlines NYC Half Marathon on Sunday, according to the New York Road Runners. More than 27,000 people are expected to participate in the 13.
