Rock Hawk 5K
The Rock Hawk 5K takes place in late August at Castle Rock's Phillip S. Miller Park, offering a manageable 3.1-mile introduction to the area's trail system. With just 342 feet of climbing and a maximum elevation around 6,600 feet, this route follows rolling terrain that's described as challenging without being overly technical. The course moves through Castle Rock's Miller Park and Ridgeline Trail systems, where runners can expect a mix of singletrack and wider trail sections with views of the surrounding Colorado landscape. August temperatures and moderate elevation mean you'll likely encounter warm conditions with limited shade in exposed sections, though the shorter distance keeps heat exposure manageable. This works well for newer trail runners making the jump from road racing, or as a shakeout run for more experienced runners. The relaxed 3-hour time limit and straightforward course make it accessible, while the rolling terrain and altitude provide enough challenge to keep things interesting without overwhelming anyone still getting comfortable on trails.
