Dinosaur Valley State Park, 1629 Park Rd 59, Glen Rose TX 76043

Jurassic Trail Run - July 8th, 2017 8:15pm (*night-run):
Come run where the Dinosaurs roamed! Long ago, dinosaurs left footprints in the mud at the edge of an ancient ocean. Today, you can run in their tracks at night, but don't let them catch you. Choose from a 5k, 15k, or 13.1 mile trail run and bring a headlamp or flashlight, because you will be running after sunset following a course of reflective arrows  to help find your way!

The 5k will follow a trail near the river, while the 15k and 13.1 mile half marathon will explore the single track trails throughout the state park and along the river. The trails can be rocky and technical in spots, so bring your sense of adventure.

For those of you that don't know XTERRA - these are the most recognizable, enjoyable, rock jumping, tree ducking, creek crossing, hill climbing, dirt on your shirt, sweat in your eye trail runs on the planet.
