About This Race

The 50K distance transforms the rocky terrain into an endurance test, with 899 feet of elevation gain spread across 31 miles of technical forest trails. Multiple loops through the Lake Perry area allow runners to settle into a rhythm with the stone-studded paths while building familiarity with the course's demanding footing. This ultra distance suits runners ready to tackle sustained technical terrain over several hours.

The course winds through hardwood forests on technical, rocky singletrack trails that demand attention to foot placement while remaining runnable throughout. The rocky terrain is characteristic of the Kansas landscape, providing consistent technical challenges without extended sections of unrunnable scrambling.

With 900 feet of elevation gain distributed across the distance, the hills are described as runnable but still provide meaningful climbing. The forest canopy offers natural shade and creates an intimate trail running environment away from more heavily trafficked areas.
