Course, venue, series, and charity
The 5K and 10K courses run along the Ralston Creek Trail through shaded creekside areas, open spaces, and nearby golf course neighborhoods. The half marathon combines the Ralston Creek Trail with the Blunn Reservoir loop and includes views of Denver and the Front Range. Colorado Tap House serves as the event venue and will host an athlete after-party with a buy-one-get-one drink offer of lesser value.
The race is part of the Run Amok Summer Series; registering for the three-race series gives a 25% discount per distance. The event is an official BOLDERBoulder qualifier, and finishing times from any distance can be used to qualify for 2027 BOLDERBoulder waves. Proceeds benefit Salute Colorado, a nonprofit supporting veterans in Colorado. Visit the organization's website for the most recent information.
