Take on the gorgeous, thrilling and rolling trails of Castle Rock’s Miller Park & Ridgeline Trail systems at Rock Hawk Trail Races.

While not overly technical, these trails will challenge and excite, as you soak up the amazing views of the surrounding front range of the Rocky Mountains. This is a great race for both first-time and veteran trail runners, and provides a nice test for those who are training for longer summer events.

New in 2024: For the first time we’ve added a two loop 50KM distance! 

We’ve also changed the half marathon course (21KM) to a single 25KM loop.
