Cook Forest 25K Trail Challenge
The Cook Forest 25K Trail Challenge is a trail race held at Cook Forest State Park in Cooksburg, Pennsylvania. The event uses a looped route that links thirteen interconnected trails and moves through varied terrain, including riverfront stretches and old-growth evergreen forest.
The course begins with a steep climb up Seneca Trail to the Cook Forest Fire Tower. After descending, the route follows sections alongside the Clarion River and proceeds through Tom's Run, a shaded area noted for consistently cooler temperatures. The route emphasizes natural scenery and continuous singletrack.
Three aid stations are placed along the course and are staffed by local high school cross country teams. These stations supply hydration and basic nutrition during the race.
Packet pickup and day-of registration are available at Shelter 2. The start, finish, and packet pickup location is Shelter 2 at 2604 Forest Rd, Vowinckel, PA 16233. GPS coordinates are 41.34609 N, 79.21845 W.
Registration is handled through UltraSignup. Lodging options near the park include cabins, campsites, and local inns. Weather can vary in the forest, so participants are advised to dress in layers and prepare for both sun and shade.
The event is organized by local runners and volunteers with a focus on presenting the park trails and supporting a community atmosphere. Visit the organization's website for the most recent information.
