Polar Bear Half Marathon & 5K : Prospect Park, Brooklyn

The event is the fourth and final stop of the NYC Parks Winter Series at Prospect Park - The Peristyle in Brooklyn. It offers in-person and virtual options with race gear that includes a Polar Bear shirt and a finisher medal.

Both routes use a USATF certified circuit within Prospect Park. The 5K is one loop and the half marathon is four loops totaling 13.1 miles. The half marathon uses on-course live time tracking with predicted finish times and split photos; runners must pass through the finish line on each loop for accurate splits and photos. Course support for the half marathon ends at a published cutoff time and participants must begin their final loop before that cutoff.

On-site amenities include an informal bag check area, nearby bathrooms and porto-johns by the finish, finish-line hydration, and refreshments provided by local sponsors. Virtual participants may log their time within the event window and receive race items by mail; bib mailing is available for a fee if registration is completed early enough.

Age-group recognition is awarded online across detailed age brackets and overall categories for all gender identities. A portion of event proceeds benefits the Never Stop Running Foundation, a 501(c)(3) organization. Live online results, same-day finish-line photos, and other race media are provided.
