  1. Climb4Change
  2. liveBIG/Castle Rock Trail Fest
  3. Tri the Rock


This professionally timed event traditionally is held the morning of the second Saturday in May.

Unique to Castle Rock, this event has participants ascend 178 feet as they climb the Challenge Hill at Philip S. Miller Park in one of five races. This race raises money and awareness for the Town of Castle Rock's Adaptive Recreation program. 

  • CLIMB LOGORace to the Top: One time, that's it! However we're talking 200 steps up.
  • Trail Race: up the stairs, down the trail as many times as you can in 30 minutes.
  • ClimbNRun 5K: New this year! Climb the stairs, down the switchbacks, and then finish the rest of the 5k on the trail!
  • Power Hour: Not your every day hour! up and down, up and down, up and well you get the picture. How many can you do in 60 minutes?
  • Run4Fun: This untimed event allows you to support the cause in a non competitive way. Once up the stairs and down the trail, includes shirt and medal. *This can be done at any time during the event except at the start of any of the above races.

Over the years volunteers, businesses, and families with children with cognitive and physical disabilities have banded together for the race and have raised thousands of dollars. All funds go directly to providing scholarships and to providing access to a wide variety of activities for these families. For more information or to register visit our Climb4Change page.
