About the Course

Fall Flat takes you along the White Trail and around Willowbrook Lake; it is flat and well suited for novice runners and walkers as well as more competitive athletes. The trails wind and turn, and you must follow course markers to ensure you head in the right direction. You will encounter uneven surfaces, gullies, tree roots, logs, rocks, foot bridges and mud - it's a trail race! The course is clearly marked with overhead ribbons. Course marshals are in place to provide assistance.
