Back the Blue
Support our boys in blue as you run through picturesque Castle Rock at the Town’s annual half marathon. Proceeds from all race distances will be donated to the Colorado Fallen Heroes Foundation to support law enforcement officers across the state. Beginning and ending in the newly redesigned Festival Park, the Castle Rock Half Marathon invites you to pick your race, cheer on your runner, or just come out to enjoy the post-race party.
