Town Races

Due to Covid-19 all town races have been suspended until further information from the state and federal government is released. We will update this page as more information becomes available.

The Town of Castle Rock Parks and Recreation department hosts multiple family-friendly races each year. These events range from swimming, biking, running, walking, stair climbing, or a combination. Check the tabs below for more information or to sign up for a specific event or series. 
  1. Climb4Change
  2. Tri the Rock
  3. liveBIG/Castle Rock Trail Fest
  4. Pedal the Moon

Due to Covid-19 Climb4Change has been cancelled this year 2020. We hope to see everyone next year for this great event!


Climb4Change is a unique racing event that raises money and awareness for the Town of Castle Rock’s Adaptive Recreation program. Volunteers, businesses, and families with children with cognitive and physical disabilities band together for the race up the 200-step Challenge Hill built into the side of a mountain at Philip S. Miller Park.

Participants ascend 178 feet as they climb to make a positive impact on the community. Since Climb4Change’s inception, program registration has increased 70% and the event has raised thousands of dollars to ensure everyone in the community has access to recreational opportunities. 

Events include:

  • Power Hour - up and down, up and down, up and down … for 60 minutes!
  • Trail Race - up the stairs, down the trail. You’ve got 30 minutes.
  • ClimbNRun 5K - Climb the stairs, down the switchbacks, and run the trail!
  • Race to the Top - one time, that’s it! Can you beat the course record?
  • Run4Fun - this untimed event allows you to support adaptive recreation 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.
