Immerse yourself in the rugged beauty of Dinosaur Valley State Park for the Night Claw race series, where runners are greeted with an array of distances and challenges designed to push their limits under the starlit sky. The event offers 5K, 10K, 20K, as well as endurance events that last up to eight hours. Each distance winds through hilly trails marked by rocky terrain and lush greenery, providing a unique blend of natural beauty and technical challenges. The Night Claw series is part of the Texas Summer Night Series, offering runners who sign up early for multiple races significant discounts on entry fees. Participants can also opt into the Midnight Monster Pass to build toward the Noche Trail Run in September by completing various distances throughout the summer. A standout feature of this race is the optional Claw Challenge, where participants are hunted down along the trails by a designated volunteer dressed as "the claw." The challenge invites runners to test their agility and speed against an unpredictable pursuer. Those who manage to cross the finish line with their tear tag intact earn special recognition, while those caught gain unique memorabilia for their efforts. The race takes place on Saturday evening outside of Dinosaur Valley State Park, starting at 7 PM. The course itself is a mix of dirt and rocky out-and-back trails that showcase over 650 feet of elevation change within the 10K loop. Runners are advised to bring hydration systems as no cups will be provided along the route. Aid stations offer essential support with food and water, ensuring participants stay fueled throughout their journey. The event is known for its friendly atmosphere, encouraging volunteers who play a crucial role in making each race successful. Upon crossing the finish line, runners can look forward to receiving custom gear such as night-themed tri-blend tees and commemorative medals. Additional awards are given out based on performance across various distances and endurance challenges. For those planning multiple races this season or looking for exclusive benefits, an Outlaw Membership offers significant perks including discounted entry fees and priority access to select events.

The Night Claw is not just a race; it's an unforgettable adventure through ancient terrain under the cover of night.
