38th Annual Prospect Park Fall Duathlon

The Prospect Park Fall Duathlon is a run-bike-run race held on a fall morning within Prospect Park in Brooklyn, beginning at 7:30 am. This marks the event's 38th year, featuring a main duathlon, a team relay duathlon, and a Volunteer 1 for 1 option. The second run covers the park’s full outer loop, a 3.3-mile course with 140 feet of elevation gain. This race concludes the organizer’s season, brings runners and cyclists back to Brooklyn, and finishes with a post-race BBQ, a long-standing tradition of the event.
