Polar Bear Half Marathon & 5K NSRF 2027
The event offers two race options at Prospect Park in Brooklyn on a USATF certified circuit. Runners follow looped courses that begin south of Duck Island and finish at the Grecian Shelter, the Peristyle historical landmark.
Distances include:
- 5K : one loop of the certified course
- Half Marathon (13.1 miles) : four loops of the same start and finish
The half marathon uses on-course splits with live time tracking and split photos. Runners must cross the finish line on each loop for accurate split times and photos. Course support for the half marathon ends before the final time cutoff.
Amenities noted for the event include an informal bag check area, bathrooms within a few minutes walk of the start and finish, portable toilets near the finish, and hydration provided at the finish line. High quality refreshments are supplied by All Round Foods and Waterloo Sparkling Water. Participants receive a Polar Bear shirt and a finisher medal.
There is a virtual participation option that allows competitors to log a time and upload up to five photos within the event posting window. Bib mailing is available for an additional fee when requested in advance.
Top finishers receive age group recognition for overall and for age brackets from 14 and under through 90 plus across F, M, and X categories. Proceeds benefit the Never Stop Running Foundation, a 501(c)(3) nonprofit. Visit the organization's website for the most recent information.
