Murrell Park, Flower Mound, Texas
Race Start: 7:00 p.m. **night run**
Choose from a 5k, 15k or 13.1 mile trail run on the Northshore Trail of Lake Grapevine. This race is part of the XTERRA Trail Running Series—some of the most recognizable, enjoyable, sometimes-rooted, sometimes-rocky, sometimes-sandy, tree-ducking, creek-crossing, hill-climbing, dirt-on-your-shirt, sweat-in-your-eye trail runs on the planet.
Bring a headlamp or flashlight, because many of you will be running after sunset, following a course of reflective arrows to help find your way! The trails can be rocky and technical in spots, so bring your sense of adventure.Register for the XTERRA Rock Dallas Trail Runs

Our aid stations are stocked with Gatorade and water. We have gone green and aid stations will not be stocked with cups. Please carry your own hydration pack to refill at the aid stations. We’ve heard other races fill packs for you, ice you down, shove Pringles in your mouth—we think that’s very nice of them, but we come from the land of grit. The land of self-sufficiency.
