The course for the Cook Forest Half Marathon — which is mostly flat with a few gentle, rolling hills — follows an out-and-back route starting at the park’s Log Cabin Visitor Center. From there, runners proceed along state route 36 to River Road, following the twists and turns of the Clarion River toward the race half-way/turn-around point, and then retrace their route back to finish line at the visitor center.
