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

The event offers two looped road race distances around Prospect Park on a USATF certified circuit. Participants receive a Polar Bear shirt and medal and finish-line hydration and refreshments provided by All Round Foods and Waterloo Sparkling Water.

  • Half Marathon: 13.1 miles, 4 loops on a USATF-certified circuit
  • 5K: 1 loop on the same USATF-certified circuit

Amenities include an informal bag-check area, bathrooms a short walk from the start and finish, and porta-johns near the finish. The half marathon provides 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 after 2 hours and 45 minutes; participants should follow the event cutoff requirements.

A virtual participation option allows logging a time during the event period, uploading up to five photos, and receiving mailed race items; bib mailing is available for $10 if registered at least ten days in advance. Results are available live online with same-day finish-line photos. Age-group recognition is awarded to the top finisher overall and in multiple age categories.

Proceeds benefit the Never Stop Running Foundation, a 501(c)(3) organization that supports athletic and charitable events and athlete development. Visit the organization's website for the most recent information.
