Murderkill Ultramarathon

Felton, United States • 26 Jul 2025

The Murderkill Ultramarathon, held at Killens Pond State Park in Felton, Delaware, offers 50-mile, 50K, and 12-hour race options on a mostly dirt 3.1-mile loop trail. The course is relatively gentle with about 80 feet of elevation gain per loop, featuring shaded paths, some roots, rocks, and a footbridge crossing. Runners can cool off by jumping into the pond near the boat ramp. The event embraces an old-school, self-supported style with minimal aid—water is provided, but no medals or chip timing. Limited to 30 participants per race, the event fosters a community atmosphere in a scenic park setting, with a focus on respect for the natural environment.
