Come out for the 9th annual spring fling on the grassy lawn at the Phillip S. Miller Amphitheater. Beach balls, hula hoops, and hot racing action. Bring your blanket, spread out on the green lawn and cheer on the racers.
This lengthened 16-mile circuit includes the new Phillip S. Miller trail system, as well as the old Ridgeline trails. The new Miller Activity Complex (MAC) was constructed on the hills overlooking the town of Castle Rock. Check out everything the MAC has to offer on Town of Castle Park’s website.
The tight course winds through Gambel Oak, Ponderosa and Pinyon Pine. Designed like Battle the Bear, the neutral aid station every lap provides excellent spectating opportunities and fast racing action.
Highlights include award ceremonies, sponsor village, park activities, and the Warriors Kidz race for ages 9 and under. Shake out the legs with the entire family at this exciting new summer venue. First 300 paid registrants get a t-shirt.
