Rock Hawk

Held on the gorgeous, thrilling and rolling trails of Castle Rock’s Miller Park & Ridgeline Trail systems. While not overly technical, these trails will challenge and excite, as you soak up the amazing views. This is an excellent race for both first-time and veteran trail runners, and provides a nice test for those who are training for longer summer events. A portion of proceeds of the race benefit the open spaces and trails of Castle Rock, and our partner charities.
