Come run Castle Rock’s newest trail race at the beautiful Phillip S Miller Park! The event will offer three distances: a 50k ultramarathon, a half marathon, and a 12K (7.5 miles). The October 9th event will highlight the freshly cut, soft surface trails that are a part of the town’s largest ever park project. The race will begin near Castle Rock’s state-of-the-art Miller Athletic Complex, a beautiful $30 million venue. The race course will showcase the newly constructed trails in Phillip S Miller Park and the single and double track trails at the adjacent Ridgeline Open Space. Don’t forget to take in the impressive views of the surrounding buttes and the scenic views of Castle Rock as the trail twists and winds over the flowing race course. If you have any energy left after your race, you can climb Challenge Hill, a 200-step staircase on the hillside near the finish line.
