# Rewritten Description

Head to O'Bannon Woods State Park near Louisville for an unforgettable trail running adventure featuring 25K, 50K, and 50-mile options that showcase the best of southern Indiana's rugged landscape. You'll navigate rolling ridgelines, dense forests, rocky singletrack, and creek crossings with nearly 7,800 feet of elevation gain and descent, with the 50-miler giving you a generous 16-hour cutoff to conquer two loops of the challenging 25-mile Adventure Trail at your own pace.
