Rock Hawk

Castle Rock, United States • 30 Aug 2025

Rock Hawk Trail Races, held at Philip S. Miller Park in Castle Rock, Colorado, offer four distances: 50K, 25K, 10K, and 5K. Runners traverse the rolling Miller Park and Ridgeline trails, described as gorgeous and thrilling but not overly technical, with sweeping views.

The course provides a solid challenge for both first-time trail runners and seasoned ultrarunners, and serves as a good prep for longer summer events. A portion of proceeds benefits Castle Rock open spaces and trails and partner charities. The event features include post-race breakfast, finisher glassware, official chip timing, two cup-free aid stations, drop bags, live tracking, and volunteer opportunities.
