The Ridley Creek State Park 25K is scheduled for October 25, 2026 in Glen Mills, PA. The course begins at Pavilion #11 and follows a single clockwise loop through the park, covering 25K of trail terrain within the 2,600 acre state park.

Runners pass the historic Hunting Hill Mansion, ascend to the top of Hunting Hill, and return along Ridley Creek. The course is described as technical in sections and tests ascent and descent ability over varied trail surfaces.
There are three aid stations located at approximately mile 4, mile 8 and mile 12. Aid station supplies include water, GU Roctane, soda and other trail snacks. Participants have five hours to complete the course.
