Castle Rock, CO



Climb4Change is a unique racing event that offers various timed challenge races on the 200-step Challenge Hill built into the side of a mountain at Philip S. Miller Park. Participants ascend 178 feet at least once in any one of the four climb challenge events. There is also a non-timed fun run/walk that families can enjoy together on their own anywhere in the park.

Proceeds from this event are used to provide scholarships, to purchase adaptive equipment, and to provide access to a wide variety of activities in a safe, respectful, and ability-focused environment to adults and children with cognitive and physical disabilities. If you want to learn more about this program or care enough to donate please visit Castle Rock's Adaptive Recreation Program.
