The Night Claw is a nighttime trail race through Dinosaur Valley State Park. Choose from the 5K, 10K, 4-hour, 6-hour, or 8-hour timed races. Runners can also opt into the Claw Challenge, where you’ll be hunted on the trails — escape with your tear tag intact and earn the title of “ESCAPED”; get caught, and you’ll be marked as “CLAWED.” Whether you outrun the claw or just come to race the night, this is one wild run through ancient land you won’t forget.See All Event Posts
