About the race

The Polar Bear Half Marathon & 5K is the fourth and final stop of the NYC Parks Winter Series, held at Prospect Park in Brooklyn. The event offers two race distances on a USATF certified circuit that loop through the park.

  • Half Marathon: 13.1 miles, 4 loops on a USATF certified circuit
  • 5K: one loop on the same USATF certified circuit

The course starts south of Duck Island adjacent to St. Paul’s Place, roughly 365 meters northeast of the finish. The finish is at the Grecian Shelter landmark, the Peristyle. Half marathon runners must cross the finish line on each loop for accurate splits and split/finish photos. Course support for the half marathon ends after 2 hours 45 minutes.

Event amenities include a Polar Bear shirt and medal, informal bag check, hydration at the finish, bathrooms within a few minutes' walk, and porto-johns near the finish. High-quality refreshments are provided by All Round Foods and Waterloo Sparkling Water. Bibs can be mailed for a fee if requested in advance; in-person pickup is also available. Virtual participants may log time from the event start day and for a full week afterward, may upload up to five photos, and will have race items shipped beginning on the event start day.

Proceeds benefit the Never Stop Running Foundation, a 501(c)(3) organization. Age-group recognition is awarded to top finishers overall and across standard age categories. Visit the organization's website for the most recent information.
