About
Out-and-back trail half marathon on the scenic Greenbrier River Trail that stays mostly on packed gravel with a few softer sections and finishes on paved/gravel road. The course is gently flat with minimal elevation gain, making it approachable for many runners while still offering classic trail footing. Small, rural event atmosphere emphasizes natural scenery and community support, with proceeds benefiting the Greenbrier River Trail Association.
