Xterra Trail Run, Castle Rock Colorado

The fourth annual XTERRA Trail Run Castle Rock. Join us at Castle Rock Colorado's beautiful Phillip S Miller Park. At an altitudes of 6,200 feet this trail run is invigorating, highlighting the freshly cut soft surface single and double track trails. Don't forget to take in the impressive views of the surrounding scenic views of Castle Rock Colorado as the trail twists and winds over the flowing race course. The course is designed and managed by the legendary runner and adventure racer Peter Maksimow. So expect a well-marked course, stocked aid stations, experienced volunteers and courses that are challenging for the elites and enjoyed by the beginner trail runner.

There are plenty to do for the entire family. The Philip S. Miller Park's outdoor space includes a playground with 60-foot slide, a 200-step challenge staircase, a turf field, and the Headrush Towers' 40-foot and 80-foot towers that kids can climb up, repel down, or even free fall from.

Cup-Free Racing! Surveys shows most runners dislike paper cups at race aid stations. That is why XTERRA Colorado Trail Run Series have gone Cup-Free. That means less litter, trash, and waste.

Cup-Free Racing is Easy!
  • Bring your favorite personal hydration device. Handheld bottle, hydration belt/flask, or any other refillable container
  • Fill it at every aid station
  • Drink, it's that easy...
