Murderkill Ultramarathon

Felton, United States • 26 Jul 2025

The Murderkill Ultramarathon takes place at Killens Pond State Park in Felton, Delaware, featuring 50-mile, 50K, and 12-hour race options. The course is a roughly 3.1-mile mostly dirt loop with minimal technical challenges, shaded trails, and opportunities to cool off in the pond. The race embraces an old-school, self-supported style with minimal aid—water is provided, but no guaranteed aid stations, medals, or chip timing.

Limited to 30 participants per race, the event fosters a community atmosphere with shared food and drink tables. Held in late July, runners should expect hot, humid conditions. Parking and park fees are included in the modest entry cost. Visit the organization's website for the most recent information.
