About the race

The Night Claw is a nighttime trail race held near Dinosaur Valley State Park in Glen Rose, Texas. The event uses dirt and rocky single-track trails and includes a river crossing. The course is hilly; the 10K loop shows about 650 feet of elevation gain. Historic night temperatures for the event range roughly from 75 to 95 degrees.

Distances offered:

  • 5K
  • 10K
  • 20K
  • 10K Ruck
  • 4-hour timed
  • 6-hour timed
  • 8-hour timed

An optional Claw Challenge lets participants opt in during registration. Each participating runner receives a bib with a tear tag; a designated volunteer runner called the Claw attempts to take that tag while running the course. If the tag arrives intact at the finish, the runner is recorded as escaped; if the tag is taken, the runner is recorded as clawed. The Claw runs the 10K loop repeatedly and may interact with runners on corresponding loops.

All participants must carry a water system (minimum 16 ounces except for the shortest event) and use a headlamp. Ruck weight rules apply for the 10K Ruck: participants over 150 pounds carry 30 lb, under 150 pounds carry 20 lb. Aid stations provide cold foods, snacks, water, electrolytes, pickle juice and ice; separate water stations offer water and ice. Drop bag transport to aid stations is not provided.
