Dinosaur Valley State Park, Glen Rose, Texas
Race Start: 11:00 AM

Choose from a 5k, 15k or 13.1 mile trail 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. The trails can be rocky and technical in spots, so bring your sense of adventure.

Aid Stations

We try to be be eco-friendly at all of our races. To reduce trail litter and overall waste, we do not supply cups at the aid stations. There will be water out on the course every 3-5 miles, but you are responsible for providing your own drinking vessel.
