Event overview
The Never Stop Running Foundation NYC Parks Series #4 Prospect Polar Bear is set for January 24, 2026 in Prospect Park, Brooklyn. The event offers in-person and virtual options with two distance choices:
- 5K
- Half Marathon (13.1 miles)
The race is the fourth and final stop of the NYC Parks Winter Series. Proceeds benefit the Never Stop Running Foundation, a 501(c)(3) nonprofit.
Course and timing
Both routes use a USATF certified circuit in Prospect Park. The 5K is one loop of the circuit. The half marathon uses the same start and finish and consists of four loops. The start is south of Duck Island, adjacent to St. Paul’s Place, and the finish is at the Grecian Shelter, the Peristyle. Half marathon course support ends at 2 hours 45 minutes.
Registration, virtual option and age groups
Registration includes in-person and virtual entries for both distances. A bib-mailing option is available for an additional fee if requested at least 10 days before the event. Virtual participants may log times and upload up to five photos during the event window of January 24 to February 1; virtual entries include shirt, medal, and name on the bib. Online age-group recognition is listed for top finishers overall and in standard age brackets from 14 & under up to 90+.
