End of the Road Half Marathon & One Tunnel 4 Miler 2026

At End of the Road in Waterfall, Pennsylvania, runners use the abandoned Pennsylvania Turnpike instead of a typical road course. The series takes place in October and includes a Half Marathon and a One Tunnel 4 Miler, with a two-day challenge for those racing both events. The appeal is straightforward and unusual: extended sections of vacant highway, dark turnpike tunnels, and autumn foliage on the ridges surrounding the old road. The half marathon covers approximately five miles within Sidling Hill and Ray's Hill Tunnels, two lengthy tunnels where participants use headlamps and glow sticks because of the absence of artificial lighting. Beyond the tunnels, the course follows quiet, old pavement and undulating rural roads on a highway bypassed decades ago and left without vehicle traffic for almost fifty years. The 4 Miler offers newer runners, walkers, and those progressing from a 5K a shorter option to experience the abandoned tunnel environment without completing 13.1 miles.
