About the Duke's Holiday Half Marathon

The Duke's Holiday Half Marathon is held in early December at Duke Island Park in Bridgewater, New Jersey, along the Raritan River. The half marathon is four laps of a 3.27-mile loop that uses the park's main road and the riverside path, with about three quarters of it under trees and about 13 feet of climbing by the organizer's count. A 10K (two loops of a slightly shorter 3.1-mile course) and a 5K (one loop) start within fifteen minutes of the half, and every loop is chip timed with splits.
