NSRF Polar Bear Half Marathon

NSRF's Polar Bear Half Marathon is the final stop in the NYC Parks Winter Series, held at Prospect Park in Brooklyn. Runners can choose the Half Marathon or a 5K and enjoy a scenic loop through the park. The event blends winter flavors with festive post-race perks, including a Polar Bear T‑shirt and a Polar Bear Medal, plus snacks from All Round Foods and Waterloo Sparkling Water.

A signature feature is the Polar Bear plunge, adding a playful, community atmosphere to the day. The race is scheduled for January 24, 2026, as part of the Never Stop Running Foundation’s NYC Parks Series. Visit the organization's website for the most recent information.
