The 15K


9+ miles. Chip-timed race. Same start/finish with mixed terrain - grass, road and dirt trails. Fossil FUEL/Hydration Station X 2. Water bottles or Hydration Packs are encouraged. Average finish time 2.5 hrs.  Recommended age 15 and up. 


This 15K trail is not to be underestimated.  Moderate to pretty darn significant elevation gains and STEEP terrain,  technical and groomed trails, low water boulder hopping across the Paluxy, loose rock and dirt scrambles, awesome views of the Paluxy Valley. Test your grit against THIS mother!
