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.

Voted Best Kids Race in Competitor Magazine’s “Best Of” runner poll, 2016.\
