About the race
Prospect Park Fall Duathlon takes place in Brooklyn's Prospect Park, starting and finishing near Lincoln Field at 116 East Dr. The three-stage course includes a 2.1-mile first run around the park's inner loop, a 10-mile bike (three laps) around Prospect Park Drive with a notable Grand Army Plaza hill and a fast downhill on each lap, and a 3.3-mile final run on the full park loop with about 140 feet of elevation gain. Attendees enjoy fall weather and foliage, plus a post-race BBQ.
The event is not USAT-certified, and no racing license is required. It is the final race of the 2025 season. Visit the organization's website for the most recent information.
