About
The Prospect Park Fall Duathlon takes place in Brooklyn's Morgan neighborhood, just outside Prospect Park. Athletes start with a run, move into a bike leg with several loops through the park, and finish with a final run.
The course includes meaningful elevation gain and a scenic backdrop, set against the colors of fall foliage. The event welcomes seasoned competitors and first-timers alike, and wraps up with a post-race celebration for everyone who crosses the line.
