Cook Forest, Highland Fall Scramble

Cook Forest, Highland Fall Scramble is held in Farmington Township, Pennsylvania, on October 25, 2026, with a single format: a 12-mile trail race starting at 9:00 a.m. in Cook Forest.

Twelve miles off-road sits in an interesting spot — harder than a road half marathon feels once the terrain is factored in, but short enough that you do not need an ultra build to get there. Two to three months of consistent running with a weekly long run of 90 minutes to two hours, at least some of it on trails, is reasonable preparation. Go out slower than instinct suggests: the opening miles of a trail race always feel easy and the last three rarely do. Carry water if you expect to be out for more than a couple of hours.
