Experience the Best Dam Run ever as you lace up your shoes for an unforgettable race along Cherry Creek Dam, where panoramic views of Denver and the majestic Rocky Mountains serve as your backdrop. This event offers three distances to choose from: Half Marathon, 10K, or a scenic 5K course. As you run alongside the dam, take in the stunning vistas that stretch out before you, transforming each step into an adventure through one of Colorado's most iconic landscapes. The race is more than just running; it’s about celebrating milestones and enjoying the camaraderie among runners who share your passion for pushing boundaries and exploring new terrain. Upon crossing the finish line, don't miss out on exclusive post-race festivities that include a free photo opportunity with Justin Beaver, refreshments to refuel, and an awards ceremony featuring event and series accolades.
