About the Delaware River Loop Series 100K
The Delaware River Loop Series turns a compact canal corridor into a long-distance test. Runners see the same support area repeatedly, which lowers navigation stress and shifts attention toward pacing and fueling.
Course
The 100K is assembled from repeated loops beside the Delaware River and canal near Titusville. The terrain is comparatively gentle for an ultra, but repetition and late-race mental fatigue are central parts of the challenge.
Race-day weather
Mid-October can bring cool, efficient running weather, but rain, wind along the water and damp footing are realistic. Layering is easier because the course returns to support often.
