Come run Castle Rock’s newest trail race at the beautiful Phillip S Miller Park! The event will offer five races: a 50K ultramarathon, a half marathon, a 10k, a 5k, and a family adventure race. The 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 doubletrack 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.
Starting near the amphitheater at Phillip S Miller Park, the course travels along the Yellow and Purple trails before crossing a pedestrian bridge to the Ridgeline Open Space. Here, runners will circumnavigate the perimeter of the Rigeline Trail counterclockwise before returning to the pedestrian bridge. Once back in Phillip S Miller Park, runners will continue on the yellow trail. Half Marathon and 10k runners will finish at the start line while 50k runners will get to experience the red and green trails within PS Miller Park. The 50k runners will then run a full second loop of the course.
The entire course is run on entirely on dirt single and doubletrack trails. The Ridgeline Trail 50k, Half Marathon and 10k is a challenging course with nearly 3,500′ of climbing in the 50k, 1,400′ of elevation change in the half marathon and 800′ of elevation change in the 10k. There will be 11 aid stations in the 50k, six aid stations in the half marathon and two aid stations in the 10k. Each aid station will provide Gatorade, water and gels. 50k runners will also find a variety of food items, including pretzels, fruit strips, Kashi bars, and potato chips.
