Cook Forest 25k Trail Challenge

Since 2018, this Pennsylvania trail running event has been a homecoming. A rugged loop strings together 13 trails through the state's natural beauty. You’ll scramble up Seneca Trail to the Cook Forest Fire Tower, then weave alongside the Clarion River. Tom’s Run paths lead through Pennsylvania’s tallest living evergreen trees, offering solitude in old-growth forests. This experience is heartfelt and hardcore.
